MathStart 1: Jack the Builder (Counting On)

Jack has the best blocks ever. They come in all shapes (square, rectangle, cylinders, cones) and colors. In Jack’s imagination, an arrangement of just two blocks is a robot. Add one more block and presto! It’s a hot dog stand at the circus. Add two more blocks for a total of five for a ferryboat. And so it goes, counting on more and more blocks, all the way to the super-duper, ready-for-lift-off rocket ship. Blast off! All the blocks fall down and it’s time for Jack to start over again. Counting on is a strategy to help young children understand how to solve addition problems. Used with permission from Stuart J. Murphy.
