The Chains of 100 and 1000 are a great way to introduce basic math concepts in a very visual way. The set includes one chain of ten golden bead bars of ten, a chain of one hundred bars of ten and a wooden rack with hooks for hanging the chains. The rack measures 20 cm x 9 cm x 7.5 cm and can be easily mounted on a wall using the two metal loops on the back. This material can be used together with the Arrows for Chains of 100 & 1000 (sold separately).
