Day 148 & 149: Four fours

I’m surprised how much students struggle with four fours. I think I should do this earlier in the school year next year so that they can practice many the standards of math practice in an environment where they are more familiar with the basic math skills required. Additionally, I should add a part 2 where students use their work to prove whether or not all numbers can be constructed using 4 fours.
