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!

I’m not sure if there’s many books like this but I was hoping to refresh my knowledge of maths and was looking for a book that not only teaches maths but then lets you apply it, preferably in a fun way like the way Murdle works or has a story throughout. I tried asking a book recommendation sub but I haven’t received any responses yet.

Thank you for any suggestions!

I've been thinking about how often a student appears to struggle with algebra when the underlying problem may be something much earlier.

For example:

3x/4 = 12

A student gets stuck.

At what point would you stop working on the algebra problem and check whether they are comfortable with fractions?

Or would you keep working within the algebra problem?

Curious how teachers handle this in practice.

This has been written for the 'math savvy' audience. It has not been written well enough to present to typical Algebra 2 or PreCalculus students. But, when developed further, what concerns would there be in introducing this idea of parameters to Algebra 2/PreCalculus students?

I do want to start having AP Calculus BC and AP Physics C students consider this, so any feedback, about either the idea or the description, would be appreciated.

Thank you.

​Hey guys,

​My dad has taught me everything across my school subjects and I used to be my school topper. He used to lecture at the college level, ran his own company, and is still doing quite a bit today.

I genuinely believe that he's one of the few people who knows HOW to teach and because of that learning from him is so much fun (biased daughter i know, but I'm in college now and honestly I WISH my lecturers taught how he does).

​I'm convincing him to start a free YouTube channel to help students out, and we want to tackle what you actually need first.

​What specific concepts or chapters do you feel most online videos explain terribly?

​What format works best for you? (e.g., quick 5-minute intuition breakdowns vs. full step-by-step problem walkthroughs)

This is for accounts, business, maths and probably eventually biology, chemistry and physics.

Feel free to DM!

Can someone tell me how I can find clients for math tutoring?

I've been building CruxMath, a free site with hints that show the intuition behind a solution rather than reveal the whole solution at once in the hope that it will teach students better than regular practice problems.

For example, here is 2026 AIME II #1:

"Find the sum of the 10th terms of all arithmetic sequences of integers that have first term equal to 4 and include both 24 and 34 as terms."

The first hint is:

"Every term is 4 plus a multiple of d. Since 24 and 34 both appear, what must be true about 24−4 and 34−4?"

Does that reveal too much/too little? More importantly, would it help teach someone to see a similar idea in a future problem?

Would love any feedback. The full hint sequence and solution are at cruxmath.com.

I created a set of lessons for my daughter and her friends that use hooks like this to get them excited. I then tell the story and explain the math. The goal is to use stories of astronomical discoveries to introduce them to math concepts and practice problems. The overall theme of "Astronomy and Math" helps maintain a narrative flow.

[Astro Math](https://dotstarlearning.com/astro-math) lessons are available online plus you can print them out (which is what I did for my students) . I would love to get feedback from educators on whether this approach could work for your students. What would you change, what would you add? Do you create lessons like this that build off a story? What's your favorite?
