Summary

When we’re adding and subtracting, do evens make odds into evens? Do odds make evens odd? Which one has… more power!?

  1. Students explain *why* adding two evens always leads to an even.
  2. Students find the rules for even+odd, odd+even, and odd+odd and attempt to explain *why* these are rules.
  3. They do the same for subtraction: what happens when we subtract even-even, even-odd, odd-even, and odd-odd? Why?
  4. Finally, your students will consider, after all this, which has more power: evens or odds?
