For most second graders, a good secret code is just about irresistible. Here's one that builds math facts while you're at it!

Here's a simple math activity that has your child using her basic addition facts to solve a secret code.

Head out to the driveway, ball in hand, for a bouncing challenge. Then use those results to make a colorful graph that lets your child compare results.

In this activity, students build a house of sticks, just like the second little pig in the classic story, The Three Little Pigs. Then, they program an educational robot to push down the house, much like the wolf who “blows the house down.”

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.
