Variable Machine
Description – An interactive variable machine helps develop an understanding of what variables are and how to use algebraic letters in expressions representing real life situations. Verbal models are turned into expressions by dragging numbers, variables and operators to the machine; the machine generates the expression and acknowledges whether or not the selection is correct.
