What's the rule? Prove it!
Write 3, 7, 11, 15 on the board and ask, "What's the rule?" Every answer needs proof: "Add 4, because 7 minus 3 is 4 and 11 minus 7 is 4." Saying the check out loud catches the kids who only looked at the first two numbers.
Why it works: when kids say the precise math words, their understanding gets sharper, a recommendation of the U.S. Department of Education's elementary math guide.
