Pre-Algebra Tutors Who See Calculus in Every Fraction

Fractions and negative numbers are where high school math quietly gets decided. Almost every problem we see in Algebra 2 — and plenty in pre-calculus — traces back to something learned around 6th grade that never quite landed. Fix it now, while it takes weeks instead of years.

“My 8th grader was so demoralized about math before working with Rebecca… Rebecca also worked hard to dismantle my daughter’s math anxiety and shame. She built a ton of trust and managed to really connect with a teen who until then had been doing her best to hide her deficits, racing through material too fast, pretending not to care, or shrugging it off as ‘I guess I just suck at math.’” — Tracy F., Parent · Read on Google ↗

Pre-Algebra Specialist · 19 Years Teaching

Sam has spent nineteen years teaching and designing instruction — middle school math and science at the American School of Puerto Vallarta, private teaching across Mexico, the United States and Europe, and middle school math in virtual classrooms since 2020. He has coached students to awards at international MathCounts competitions.

He holds a Stanford certificate in Growth Mindset Math and a virtual teaching specialization from UC Irvine, which matters more than it sounds: he has spent a career on exactly the ages where students decide whether they are “a math person,” and on teaching them out of it. He opens his video with a math joke. We have chosen to keep it in.

The Alexander Difference

Passion + Purpose = Empowered

When math serves your student’s passion, it has purpose. When it has purpose, something remarkable happens — they become empowered to use education to achieve their dreams.

Read our four-year study of Passion + Purpose tutoring →

Personalized Matching = Student Passion

We start by learning what lights your student up — music, sports, art, science, anything. Then we match them with a tutor who shares that passion and shows them how math is the hidden engine behind the things they already love. When math serves something they care about, it stops being a chore.

“His high school teachers were great, but were not able to provide the depth and level of support that was needed… His grade went from a C- to an A- within the year he was tutoring… His confidence in math has accelerated to a point where he is planning to take a dual enrollment college calculus course next year as a senior in high school.”


— Krystal M., Parent · Read on Google ↗

Deep Understanding = Purpose

Most students survive math by memorizing formulas — until one curveball on the test sinks them. We teach the why behind every equation, deriving formulas and connecting them to the real world. When your student truly understands the math, they can solve anything a teacher throws at them.

“Tyler at Alexander Math and Physics tutoring helped my son to test into Algebra 2 honors! His math grade in school went up to an A. Then when we told him he could stop tutoring with Tyler he didn’t want to stop tutoring because he enjoyed what he was learning.”


— Alexandra N., Parent · Read on Google ↗

Confidence First = Empowers Students

There’s no such thing as being ‘bad at math’ — only bad math experiences. A harsh teacher, embarrassment in class, one bad test — and suddenly your student decides they can’t do it. We rewrite that story. With a supportive tutor who believes in them, ‘I can’t’ becomes ‘I’ve got this.’

“Being a straight A student, it was difficult to accept her lower grades and it affected her confidence… within two sessions, my daughter felt more confident in Algebra, her test scores improved… My daughter had not only improved her grades but also developed a genuine interest in math.”

My 8th grader was so demoralized about math before working with Rebecca. In addition to identifying and targeting her areas of struggle with the school material, Rebecca also worked hard to dismantle my daughter's math anxiety and shame. She built a ton of trust and managed to really connect with a teen who until then had been doing her best to hide her deficits, racing through material too fast, pretending not to care, or shrugging it off as "I guess I just suck at math." Together they worked to fill the gaps left after struggling through the pandemic and remote classes, and get my daughter excited about the subject again. She brought her grade from a C to an A, but more importantly, she's not embarrassed to ask for help anymore. Rebecca is a game-changer. We've also really utilized the skills videos and progress reports provided in addition to tutoring.

I am telling you: If *my* rising 8th grader can do well in math after working with an Alexander Math tutor, anyone will. She worked with Gerald all summer, which she was less than delighted to hear when we told her about it, but she quickly stopped complaining after they started their work together. Last night she told us that she'd like to KEEP working with him once school starts so she doesn't fall behind. What? Thank you Gerald and Sean for giving her the confidence to go back to school this week feeling confident.

When my daughter was looking to go beyond her middle school math class, we were fortunate to find Alexander Tutoring. My daughter worked weekly with her fantastic tutor, Jonathan, throughout 7th & 8th grade. He not only helped her fill in the gaps in Algebra I so that she was able to successfully place into Honors Algebra II for high school (her goal!), but was also super flexible and engaged with her in exploring advanced conceptual math (for example, venturing into trigonometry and calculus, and particularly quantum physics) The online platform, which she was apprehensive about at first, worked really well, and she always looked forward to going online for her tutoring sessions. We would absolutely continue with Jonathan in high school, and I wouldn’t hesitate to work with Alexander Tutoring again to provide support for my younger daughter, who struggles with math, as she heads into middle school.

We’ve had an amazing experience with Alexander Tutoring. Our son is working on 8th grade math to prepare for starting 8th grade in an advanced math program, and the tutoring has done a fantastic job keeping him engaged, confident, and excited about excelling in math. One of the biggest surprises has been how seamless the online tutoring experience has been. Our tutor is in New York, and we live in Colorado, but the distance has not been an issue at all. It has actually been incredibly convenient, especially with our summer travel plans taking us from Hawaii to Virginia. The video sessions work great, and the shared whiteboard makes it easy for our son to follow along, work through problems, and stay actively involved. We’re really grateful for the support Alexander Tutoring has provided and would highly recommend them to any family looking for high-quality math tutoring.

Alexander Physics and Math Tutoring has been a fantastic partner to us for two of our kids in high school physics and middle school math. Both kids agree the extra help and attention on their school material made a big difference, because the tutors who took the time to get to know them and how they best learn. We saw the results in their test results and, more importantly, in their positive attitudes toward these subjects that had previously caused them stress. Special kudos for Rebecca and Gerald!

After 2 years of home school during the pandemic, my child entered 6th grade struggling significantly in math, and it affected her self esteem as well as her engagement in school. After working with Angelique over the summer, she not only started 7th grade feeling confident, but has been excelling and advancing in math classes. Charley also made a strong connection with Angelique and is excited for their weekly sessions. Angelique has transformed Charley’s attitude toward math and ignited a curiosity for more. All the staff at Alexander Tutoring is responsive, engaged, and committed to my child’s experience. I HIGHLY recommend

I hired Alexander Tutoring to help my son prep for the math portion of the SSAT middle school exam. I had interviewed a few different tutoring services, but I ultimately went with Alexander Tutoring. I was impressed by Sean's approach to teaching and philosophy of encouraging inspiration. We worked with James, who was amazing. James had a patient, relaxed, encouraging vibe that put my son at ease and allowed him to flourish. In the end, my son did great on his exam. Thank you Sean and James! I highly recommend them and would hire them again without hesitation.

We signed up for a trial with Sam for our daughter. He was awesome and we have now signed her up for the entire summer schedule. Sam has a really nice and easy communication style and once he found out that my daughter loves soccer he added a lot of soccer themes to his teaching (angles, corners, distance etc.). My daughter really liked his style and she was more than happy to continue with Sam as her tutor. My daughter is entering middle school and she needs a confidence boost in Math and Sam provided a great platform for that.

Set your kids up for success...the best advice one of my friends gave me was to start my son with Alexander Tutoring before he started his freshman year at an independent high school. My son was a progressive middle school and I was not really sure how he would fare with Physics and Algebra. Alexander tutoring was amazing in that Sean assured me that my timing was just right at the beginning of the school year and we engaged with Felix (my son's tutor) right away. My son and Felix meet on a weekly basis and even though..or more accurately because my son is getting As in both Physics and Math, we are keeping the tutoring going!

Can't say enough about them! Jonathan has been tutoring my daughter in 7th grade math and she's not only doing so much better in her work-finding that it makes sense in a way she struggled with before-but her confidence level in class has jumped leaps and bounds. She's actually enjoying math! He's very patient and has a way of explaining the "hows and whys" of the problems she's working on in a way that makes sense to her. I really like the fact, as well, that I can contact him any time to suggest material he can cover, or ask questions. Scheduling is accommodating and a breeze and communications-both with office staff and Jonathan are easy and effective. Thank you!!

We engaged the services of Alexander Tutoring for both of our sons with great success. Our 9th grader participated in the summer intensive last summer to review math concepts to feel confident with high school Algebra. His experience was very positive, he was ready to attend every session, appreciated his tutor Charlie, and felt like he was much more solid on an array of concepts. It really boosted his confidence going into high school, which was very valuable. Our younger son received tutoring during this last fall semester for review of concepts he needed more grounding in as a 7th grader. He also had success and gained confidence with each session, enough so he felt he could move forward on his own after winter break. Sean was great to work with when we had scheduling conflicts or illness, and locations for tutoring were convenient. We highly recommend Alexander Tutoring for learning and building confidence.

My son has had two excellent math tutors (6th grade math) from Alexander Tutoring. His favorite tutor by far is Wilder -- he has an approach that makes my son feel comfortable and makes the subject matter not intimidating and approachable. Many tutors from other agencies have been condescending or unable to connect with our son who struggles in math -- Sean hires tutors that are the exact opposite -- our son is more confident following his tutoring sessions because of that. In addition, Sean runs the company very well, the sessions are organized, calendared with no cancellations for us so far. Any potential changes are communicated way in advance. thank you Sean for running a great organization! well worth the investment!

My child had a wonderful experience with SA tutoring this summer. Chase was reluctant and not at all enthusiastic about doing work over the summer. His tutor Olivia not only made it fun and interesting but also helped him with his summer homework. This has made Chase feel more comfortable about entering the 7th grade, feeling caught up on his work but also having a better grasp on what is to be expected in this next year. In addition I appreciated their willingness to work with our schedule, and their options on different meeting locations in the city.I highly recommend Sean Alexander to anyone looking for good, solid tutoring help.

My kids have historically not struggled with math but this year both (7th and 12th grade) hit a wall due to issues with teachers (teaching the subject for the first time) and concepts not being explained very clearly in class. I wasn’t sure where to turn to for help outside of school and was so relieved to find Alexander Tutoring! Not only was the team great to work with to match with a tutor and schedule a regular meeting day, and explaining everything very clearly along the way, but the tutors themselves have been fantastic. If you have teenagers then you’ll know how hard it is to get them to actually like working with an adult in school subjects, as in stay engaged and respect them. Both of my kids give a solid thumbs up and have gained a great sense of confidence for each of their math classes. And my son (12th grader) really appreciates the office hours and benefits greatly from working with Alexander tutors. We are considering adding on Physics tutoring as well to really deliver an edge in class for my son, and my daughter (7th grader) is now focused on getting ahead with Algebra 1! Thank you Alexander Tutoring!

We've been with the math tutor on and off for 3 years (5th grade - 7th grade), The tutor is kind and engaging in their style, and the tutoring is high quality. My kiddo enjoys the lessons and it's been useful in building their confidence and helping them understand the material that they've been unsure of in class. Alexander tutoring is easy to deal with and flexible. They're pricier than other tutoring options but overall I feel it's been worth it for our family in terms of what our child has got out of it, so I'd recommend them 🙂

Sean is a wonderful math tutor! Sean tutored both of my boys, in grades 8 and 6. Very different situations, equally great results - I'm highly satisfied with Sean.Last year, my 8th grade son needed help with the math sections in the SSAT/ISEE exams -- the exams required of San Francisco's private and parochial high school applicants. My eldest son was stressed about the math sections, but Sean calmly and enthusiastically diagnosed which areas needed help, and tackled each area of need. Sean provided guidance and very practical tutoring, including drills and reinforcement. Sean was very patient throughout it all. My son made big gains, did great on the actual exams, and got into his top high schools. Thank you Sean!My 6th grader was in a completely different situation. This younger son absolutely loves math, was bored at school, and I approached Sean about providing summer math enrichment tutoring for him. I wasn't sure exactly what this entailed, but I trusted Sean would figure out it. Sean did -- with accolades. My math loving son was thrilled with finally being challenged and completely engaged. They explored all sorts of math concepts, advanced topics, and very practical techniques to reduce errors and develop good math habits. This son had a great summer of math and wants to continue lessons during the school year so he can continue his independent study and love for the subject. By the end of the summer, my 6th grader is doing 11th grade work. Bottom line, Sean is an effective teacher who understands kids, figures out how to help each one individually and engages them through the process. My husband and I highly recommend Sean!

We took an opportunity last year to have our 8th grader participate in a tutoring program outside of school. This group of highly educated folks were a hit for my son and a success for his math grade. They fill up quick but they definitely worked hard to find us an opening or even make an opportunity happen for us. They have a straight forward upfront no gimmick operation. My son's grade did improve and I would recommend my children going back to them.

The year that decides high school

Nobody tells you this: the math that wrecks juniors was taught to them in middle school. Fractions. Negative numbers. What happens when you multiply two of them.

We have watched pre-calculus students stall on arithmetic they were marked “proficient” in at twelve. That is not a failure of intelligence. It is a gap nobody went back for — and the standardized curriculum is built to move on regardless. The research backs this up: in a large longitudinal study, fifth graders’ knowledge of fractions and division predicted their algebra and overall math achievement in high school (Siegler et al., 2012).

Going back for it now is the highest-return thing you can do for your student’s next six years. Mastered here, these skills stop being the reason every future class is harder than it needs to be.

What Our Pre-Algebra Tutors Cover

Pre-algebra is where math stops being arithmetic and starts being reasoning. The students who struggle here usually are not behind on skills — they have hit the first topic that cannot be solved by memorizing a procedure. Here is what we work through.

Pre-Algebra Tutoring FAQ

How much does pre-algebra tutoring cost?

Pre-algebra tutoring is part of our monthly plans. Dedicated Tutor is $895/month: a weekly one-on-one session, nightly office hours for homework help, monthly progress reports and direct tutor access between sessions. The Rocket Star Track adds a second weekly session for $1,745/month. No signup fee, no contract, cancel anytime. See all plans.

What grades do you tutor?

Middle school math: Math 6, Math 7, Math 8, Pre-Algebra, Accelerated and Honors Pre-Algebra and introductory Integrated Math. We also work with younger students who need fractions and number sense shored up early.

Why does pre-algebra matter so much?

Fractions and negative numbers are where high school math gets decided. In a large longitudinal study, fifth graders’ knowledge of fractions and division predicted their algebra and overall math achievement in high school (Siegler et al., 2012). Fixing those skills now takes weeks instead of years.

My student is anxious about math. Can you help?

Yes. Middle school is when students decide whether they are “a math person.” Our tutors rebuild confidence alongside the skills, starting from what your student can already do and connecting math to what they care about.

Can you help my student get ready for Algebra 1 or an accelerated track?

Yes. We preview the skills Algebra 1 leans on most, especially fractions, negatives, exponents and equations, so your student starts the course ahead instead of catching up. See algebra tutoring.

Do online lessons work for middle schoolers?

Yes. Lessons are one-on-one on a shared digital whiteboard, so your student is working the whole time rather than watching. Sessions follow their class and homework, and parents get a monthly progress report.

Who are your pre-algebra tutors?

Mathematicians, engineers and veteran teachers with degrees in their field, never college students, including Sam Uber, who has spent nineteen years teaching middle school math and science and holds a Stanford certificate in Growth Mindset Math. Every tutor is ranked nightly on our Rocket Star Rank, so your student is matched with tutors who have already proven it. You can meet the team before you book.

What if tutoring doesn’t work?

Dedicated Tutor and Rocket Star Track plans are backed by our Full Semester Guarantee: if you’re not satisfied at the end of the term, we refund every penny. Your first lesson is risk-free, so you can see how it works before you commit.

What actually changes

Most tutoring gets a student through Friday’s test. That’s not what we’re for.

Your student learns where every formula comes from — so a problem they’ve never seen stops being a threat. They stop asking whether something will be on the test and start asking why it works.
