Marvelous Math

Learn a foolproof method for ensuring that children master their facts, as well as a potpourri of games and tricks to improve accuracy and enable children to compute huge problems easily and correctly. These include Krypto, adding by endings, Gelosia multiplication, and short division. You'll also learn "Casting Nines", a quick technique for checking computation which many children view as a sort of game and which will improve their accuracy, especially with large problems.

Before watching the workshop, you might want to print out the handout, as you'll be asked to do practice problems on it. The video is one hour and eight minutes long, and its intended audience is people teaching math to elementary and middle-school aged children.
