On June 26, Lane and Sharon Bartak read The Mixed-Up Truck to 28 children. The book is about Cement Mixer’s first day on the job and he doesn’t want to make any mistakes. How can he help the other trucks on the construction site? By mixing some powdery white cement, of course! He mixes it up, adds a little water, and presto . . . a cake?! He’ll keep trying until he gets it right. In the process he learns that making mistakes is not always a bad thing. The children also enjoyed making Fourth of July cards and playing Firecracker, Firecracker, Boom aka Duck, Duck, Goose.
