These resources provide a dynamic way to introduce and understand the Distributive Law of Multiplication and the Perfect Square Identity.

Similar in structure, they use animation to explain the difference between a variable and a constant, and then move on to the idea of an algebraic identity via varying and non-varying area models.

These videos are accompanied by a classroom-ready unit of work designed to reinforce the identities at play in the areas of our curriculum that are loosely addressed by the procedures of “expand” and “factorise”. Supporting resources for your fx-1AU GRAPH, fx-Cp400 ClassPad II and older graphics models can be found below.
