It started when Chris tried orienting blocks for his skates in a new way – and a very tricky way! He oriented the blocks on their edges – quite a challenge.
This inspired Josie to do some skating. Then Lila grabbed some Tinkertoy cars . . .
Then Josie's skate broke. She decided that a tool was needed – she got a yellow Tinkertoy rod and dubbed it her "sewing kit" and "sewed" the roller skate. Lila liked this idea, and she proceeded to take her roller skate apart and ran off to grab her own tool and the two of them worked for quite a while, side by side, taking apart and fixing their skates.
