These blocks can be used in teaching of decimals. The biggest block can be considered as the unit, consequently the plate becomes tenth part of it i.e. 0.1, the rod hundredth part of it i.e. 0.01 and the small cube becomes thousandth part of it i.e. 0.001. This kit is useful for decimal notation as well as addition and subtraction of decimals.
