This is an activity I used with my 7th grade Pre-Algebra class to review proportions, scale drawings, and similar figures. There are 15 questions:
8 - word problems
1 - determine if figures are similar
2 - finding the missing side given two similar figures
2 - determining if a pair of ratios form a proportion
2 - using the cross-product to find the missing variable in a given proportion
An answer key and student work document are also included with this product.
