This product briefly reviews perimeter and area with numbers, but then it scaffolds into finding the perimeter and area of shapes with variables and constants as expressions.
It progressively gets harder from one term to two terms in a length of one side. It also focuses on having to write an expression that can be long expression then to a simplified expression. The last two pages are word problems on perimeter of irregular shapes.
