0Class 301 has won a real truckload of number cubes. Fractions Frank, the caretaker, has found some boxes that hold different amounts of cubes--ones, tens, hundreds, and thousands. The children see how the smaller boxes can all fit into the larger ones. They put these groups in columns to create a numeral. And just when they think they are done, another truck pulls up and they have to start again! Simple sentences and easy-to-understand exercises help make learning about place value understandable and fun.
