Economy Beads
A wooden box containing:
nine unit beads
9 tens beads bars (invidual beads threaded on wire)
9 hundreds squares of beads (connected beads).
Initially just one of each of the units, tens and hundreds are presented to the child in a Three Period Lesson. Once the child is familiar with their relative values the child learns to count using the beads. The material shows how the decimal system changes hierarchy at 9, so children learn that after 9 units the next number is 1 ten which is made up of ten units etc.
