Math Links for Week Ending Feb 28th, 2025

Featured Links

I have always liked row games as a way to have a more interactive worksheet. The idea is that you have two columns of questions and you pair students up. Each student chooses a column and does all the questions in that column. They check their answers by seeing if they get the same value for their questions that are in the same row (even though they are different questions). They take some time and planning to create so it's always great when someone makes one (or some). Here are some that I've made.

Year's ago we used to have a grade 12 math course where proofs were a fundamental part of the course. I loved that course. This would have been a good relationship for it.

This would have been another great question for that proof course from the past. But now you could use it in our grade 9 course when you talk about properties of numbers.

Had lots of fun recreating a pattern @n-gons.bsky.social recently posted but with a minor twist using #TileFarm studio. I used two colors for clarity, but this is made using a single tile based on a geometric series of 30-60-90 triangles. #tessellation #iTeachMath #Math #MTBoS #mathart
