Looking for some self checking worksheet for my 7th grade math students. I would love to purchase a workbook that has several different types of activities across all of my content for the year. Looking for thing where students solve problems and their answers spell out an answer to a riddle or joke or other more engaging sheets then just solving then problems.

Hi all, I grew up in a jurisdiction that required 12 year olds learn binary number arithmetic - for additions and subtractions - using standard mathematics concepts of carry and borrow. It was geared towards forcing students to learn that the concept or carry and borrow can be stretched beyond the decimal systems. (no two's complements here)

I remember binary subtractions were very tricky to master even for gifted students. I never passed in binary number arithmetic because I couldn't do subtractions consistently. That was back in the early 1990s.

Then I immigrated to New Zealand and continued my high school years there, and had discovered that binary number arithmetic wasn't a topic in New Zealand secondary Maths curriculum. And probably for most other countries too.

So was it always a niche or difficult topic in Maths education, and not many countries' education systems taught/teach it? Thanks.

PS: just to clarify binary arithmetic wasn't taught for computing or early computer engineering, it was basically about teaching number systems and getting students to become flexible with arithmetic techniques when the base is no longer 10.

I’m a senior in highschool and I’ve always dreaded studying math for a test at home by myself. When I’m redoing the problems we did in class from my notebook, theres always a step between equations that I don’t understand how i got (Or how the teacher got). I feel like I can’t catch up with the rest of the class and don’t learn at such speeds as the others and just feel stupid and helpless. Told the teacher about it and he just sent me online videos which help absolutely nothing. Math is my poorest subject and I want to learn it but i just feel like my brain isn’t made for math and theres so many things from other lectures you have to connect to the current lecture in order to solve the problem. I just can’t keep up with all of it. And even if I do understand some lectures, when i solve the 10 task test preparation sheet at home and seem to understand everything, i still get bad results the day later because the test is so much different to the preparation sheet. How do i study math?

I’ve been building kinemo, an open-source Python library for math animations, and the latest version adds interactive lessons.

You write the lesson as a short script: the animation explains, then stops at a question. The learner picks an option, moves a slider, types a number or drags a point, and what plays next depends on the answer: a hint and another try, or the next step.

Here’s an example lesson, the derivative as the slope of the tangent: https://m4nd0r4s.github.io/kinemo/lessons/slope/

The same script also gives you:

A page you can put on any website or LMS that accepts an iframe. It runs on cheap phones too, and the platform can receive the answers if it wants to grade them itself.

A quiz video for YouTube or a class: each question shows on screen with the options and a countdown (“pause and answer”), then the right answer is revealed.

It’s free, it runs 100% locally, and you need to be comfortable writing a little Python. Docs: https://m4nd0r4s.github.io/kinemo/docs/

I’d love feedback from people who teach. What kinds of questions would you want in a lesson like this? What would stop you from using it?
