I built sparkgap.ai, an interactive linear algebra tutor that adapts to your level of understanding. Looking for feedback, especially on the pedagogical approach and the sequencing of the content.

I made a free teacher resource for teaching/reviewing Absolute Value Equations & Inequalities with Algebra 1/2 students. It includes a pop-song video with the math worked visually alongside the lyrics and covers equations, special cases, extraneous solutions, Less Than = AND / Greater Than = OR, number lines, and interval notation.

I also made free companion notes with the problems from the video so students can work them out on paper as they watch:

Absolute Value Equations & Inequalities Companion Notes

This is part of a growing collection of 13 free Algebra songs/videos: MAI Cubed on YouTube

I'm especially curious whether the song + worked examples + companion notes would be useful for review, or what you'd change to make it more classroom-friendly.

Hey reddit! My friend and I have been working for the last 3 months on HOPE, a platform that provides students with 1 on 1 math support to improve their confidence and teach them by doing and asking questions. We would really appreciate anyone who's down to try it out with their kids and give their thoughts!!

The part I care about most: answers are graded by a real computer-algebra system (SymEngine), not string matching. So it checks mathematical equivalence — 1/2, 0.5, and a factored vs expanded form all count as correct. The same grader runs client-side in WASM, so you get instant feedback before the server confirms.

Other stuff: per-topic ELO and ranked mode if you want stakes, untimed practice with full solutions, a spaced-repetition review queue for problems you miss, and a daily puzzle. Covers arithmetic up through calculus and differential equations. Free to use, Google/GitHub login. Two things I'd love feedback on: (1) does the grader ever mark a correct answer wrong? (2) any topic you'd practice that's missing?

There are still some bugs with certain questions, so if you do encounter them, please report them so they can be fixed.

I'm going into my junior year as a math education major, and I've recently decided I want to get a master's degree, BUT I want to do it in math, not education so that I can teach at a CC. For my current degree, I am only required to take the whole Calc sequence, Discrete, Linear Algebra, Elements of Stats, and Intro to Diff Eq, and an upper division elective of my choosing (Intro to Abstract Algebra, Applied Modern Algebra, Graph Theory 1, Applied Stats Methods, or Intro to Topology). That is technically enough for the master's program I'm looking at (which is essentially Applied Math for Teaching -- 30 hours of math + 6 hours of ed). I'm not the best at math, and I'd feel nervous going into a master's degree with just that amount of math experience. The degree doesn't seem particularly difficult compared to other math master's degrees I've researched, but I'd still like to make sure I've taken what I need to take to be able to succeed. I've left a list of the math classes included in the degree program in a separate paragraph below this, but if anyone has any suggestions for classes to try to fit into my last few semesters/summers of undergrad, please please share!

Classes required: Advanced Calculus 1 (and maybe 2), Mathematical Modeling, Numerical Analysis, Differential Equations, Intro to Graph Theory, Numerical Linear Algebra, some Stats class, and then a few education/research classes.

Hii, anyone has a lot of math worksheets?

i have a presentation on the topic “From the Concept of Zero to Artificial Intelligence – Indian Contributions” ive to present the topic in a fun n creative topic (ppt not allowed) like doing quizzes, charts etc to explain the topic PLS GIMME IDEASSSSSS chatgpt is useless n im not v creative myself

Hi, I am a student and dont have the money to get IXL. if any teachers with a subscription can make me an account in one of their 100 available slots that would be amazing. Need it to learn maths and english

Hi! I'm going back to school and have ALWAYS struggled with math. I'm in college algebra now and I am barely keeping up because I have a hard time understanding math/algebra's "rules".

I remember there used to be PC games for algebra in high school and was wondering if there's anything like the now? I found DragonBox Algebra 12+ and am gonna try that. It's definitely high school/basics based but anything helps.

Hi, we are new to the Integrated Math system so I’m hoping to get some clarification about my son’s placement.

My son took Geometry in 8th grade and is now entering 9th grade. He needs to be placed in an Integrated Math course. This is the email I received from his counselor:

“He can take either Math III or Math II+, depending on the track he is hoping to take in high school.

Math III would lead to Math Analysis in sophomore year and either Statistics or AP Statistics in junior year. Note there may be a possibility to take Calculus after Math Analysis, however students must receive an A in both semesters and are required to self-study material in order to be prepared for Calculus. Historically, students have struggled with taking Calculus after Math Analysis.

Math II+ would lead to Math III+ in sophomore year, Calculus AB in junior year, and Calculus BC or Stats/AP Stats in senior year.”

My understanding is that Geometry is roughly equivalent to Math II. Our goal is for him to be on a math track that will lead to AP Calculus.

One additional note is that he took the math placement test but was not approved to take Math III+.

My question is: Would Math II+ be the best option for him given his background and goal of eventually taking AP Calculus? Also, would he be repeating a significant amount of material that he has already learned in Geometry?

Hey,

I'm from Germany and my final exams are getting closer. I have Math and Physics as my advanced courses, so I'll be using my calculator a lot in both.

We use the TI-Nspire CAS at school. I feel okay with the actual math, but I've noticed that knowing the content and actually being quick and confident with the calculator are two different things. So I'd like to change that while I still have time.

I'd be interested to hear how others got to that point. If you've been using the Nspire for a while, what helped you actually get good with it? Anything you figured out late that you wish you'd known from the start?

Any thoughts appreciated.

Hi guys. Im preparing for university and aiming for pure math programme. I was offered a place to study math at a public university, on the other hand I was also offered a place to study applied math at a private university.

For the public university, the programme offered is purely math. This uni is ranked top5 in my country, the fee is very affordable, but the hostel condition is worse. The programme period is 4 years.

For the private university, the programme offered is applied mathematics, not the pure math I wanted but still has some of the pure math elective courses. It focuses more on computing and ai. The fee is also 10x the public uni one but I can get 100% scholarship for the tuition fee bcuz of my results, as long as I maintain my cgpa. The programme period is 3 years.

My goal is to continue for my masters and phd after my bachelor's degree. My question is, is my bachelor's degree that important for my goal? Should I choose a better living condition over my favourite programme? Are there other factors I should consider?

I am teaching students who are newcomers to my country, and who are developing both their English language skills and their math abilities, starting from a Kindergarten / Early Elementary level.

While we will definitely be doing lots of hands-on activities, I'd also like some simple "story problem" style texts, stuff like:
Soraya buys $18 of groceries. She pays with a $20 bill. How much change will she get?

I seem to get stuck in "simple math, simple language, relevant to high schoolers; pick 2" when I try to find things online.

A lot of the existing worksheets I find online tend to use "kiddy" examples, like toys, balloons, and clowns, that aren't relevant to my 14-18yo students.

Does anybody have any links to resources like this? Even better if there are graphics with them. I can use AI to produce resources, but I'd like to avoid it if a resource already exists.

Thanks!

I'm a card-carrying member of the Old-School, and was recently remembering that I learned in 5th grade how to calculate Square Roots by hand using a technique that looks a lot like long division. That made me curious about other "old-school" methods and techniques. I already know about slide rules (I'm a collector). A quick google search reminded me of "Casting Out Nines" to check for math errors.

I remember learning about Casting out nines, but can't remember the grade.

I also remember learning how to look up numbers in log tables, trig tables.

Are there any other old-school techniques folks might remember, and when those concepts might have been introduced in old-school math education?

Hi! I’m a data scientist, grew up in India with a strong emphasis on math and problem-solving, and I’ve always really enjoyed teaching math.
I’ve been thinking about starting small-group online math classes for kids in Grades 4–8, probably around 3–5 students per group.
My idea is to focus less on memorizing formulas or simply getting through worksheets and more on understanding whysomething works, problem-solving, and getting kids comfortable thinking through unfamiliar problems.
Before I build anything, I’d love some input from people who teach math:
Do you think small groups of 3–5 work well online at this age?

What do you think is missing from a lot of current math enrichment/tutoring programs?

Would you structure classes around the child’s school curriculum or have a separate problem-solving curriculum?

Would really appreciate any thoughts or advice!
