Activity 2: Beadsticks

This ITP allows you to place beads onto sticks representing units, tens, hundreds and thousands. If you fill any column with ten beads an animation shows how they combine to make one bead in the next column.

Similarly, if you subtract a bead from an empty column, an animation shows how one bead from the next column becomes ten beads in the empty column (and nine beads when one is subtracted).
