The 120 bead string is such a versatile tool - think of it as your physical number line.
Ours goes beyond the standard 100 beads up to 120 with a different colour system for the additional 20 beads so that students can explore numbers beyond 100 as well as allowing for decimal exploration with older students. Explore counting, calculating, 4 operations, fractions, place value and calculation strategies.
Colours may vary to sample shown. 6mm beads - string is approx. 120cm long.
