The unique design of this ruler helps introduce and reinforce fraction concepts, while also teaching basic measurement. Each clear plastic layer is marked with color-coordinated lines and its own tab, which enables students to see and understand the lines on any ruler. The ruler measures 1-30cm and features a list of popular metric measurement equivalencies on the reverse of the opaque white layer.
