83 – MathCounts elective

Our school offers a lot of great things, unfortunately Elective classes are not among them. Firstly, it’s only 3 days a week — Tuesday, Wednesday, and Friday — for 30 minutes each.

Most of my algebra kids are done with the two visual patterns that I’d randomly assigned to each one of them. They are really getting better at figuring out the equations! I’m so pleased to see that the more practice and exposure they get, the better they are at seeing patterns and reaching the formulas. So now […]

81 – feeling blessed to have a good sub

I’ve been absent from school this year more than any other. I’m committed to two ongoing math workshops where I’m one of the presenters, added to this was CMC-South which was a new one for me. I think most teachers would agree with me that writing sub plans is way harder than just showing up and doing […]

75 – pattern blocks, visual patterns, Yajilin puzzles

I really like how this handout (page 2 has the answers) makes kids think more flexibly about fractions. We just got started today, half of the class is struggling quite a bit. A couple of students were done but made a few mistakes that they needed to fix. I want to add more problems to this handout! […]

74 – the brownie puzzle

The geometry kids whiteboarded the Brownzie Puzzle by James Tanton.   The bottom two pictures show what the kids drew when I told them to use, “wishful thinking” strategy.
