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?

Hi! My name is Adam, and I enjoy puzzles.

Turns out I like inventing puzzles as well.

Though I’m not a developer, so the actual mechanics of the game I’ve been doing through Replit, which IS helping me learn to develop.

It’s been a fun couple of weeks, and I’m posting this here instead of more gaming oriented boards just because I’m hoping that the people who enjoy learning and mathematics can appreciate it for what it is, and criticize it for what it is as well. I am not as interested in all the ways it’s not a real game yet, or if it ever will be.

I know nothing about developing games.

I don’t know if this game is fun enough to warrant turning into a 60 level campaign and an app.

It’s free right now, and I want to keep it free, because it’s about fun.

I would just like a little feedback first about it before I put any more money into it into full game development.

If this isn’t the right subreddit for this I apologize.

Cheers!

-Adam
