Bead Numbers

Bead Numbers is a place value investigation involving a tens and ones abacus. First select how many beads to work with from 1 to 9. Arrange the chosen number of beads on the abacus spikes to find all the different numbers which can be made, and enter each number using the keypad on the right.

This game will challenge the understanding of place value and it provides a good context for encouraging learners to think systematically in order to find all possible combinations. It offers the chance to focus in particular on reasoning and problem solving.
