If you have bought and printed Discovering Rules of Divisibility and the set of Find Factors Cards - all numbers 0-144, you might find this teacher guide useful. It suggests ways to teach the concepts and use the cards.
Why do I focus so much on divisibility? Because it’s fun and it helps show that math is made up of puzzles, not problems. Also, it’s incredibly useful when it comes to . . . fractions!
