Since introducing the Rice Activity, Little Bear has requested to play with the Rice box daily. One thing I offered him recently was a tray of rice. It started out that he wanted to play with his cars on a thin layer of rice. But then he began to discover (his own discovery) that he could "draw" with his finger. So, he started making shapes.
Later, he requested that I help him draw letters in the rice.
He enjoyed both watching me draw the letters and tracing them afterwards. He then found my letters to be a good "racetrack" for his matchbox cars. (Notice the broom nearby. When the rice is out, so is the broom!)
