Product Description
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.

Students should download a free QR code reader to their phone or tablet prior to arriving to class. After answering a question, students can self-check by scanning the QR code. The correct answer will appear on their device.

PLEASE NOTE THAT TWO VERSIONS ARE INCLUDED IN THIS DOWNLOAD. YOU MAY CHOOSE TO USE THE COPY WITH THE QR CODES OR THE COPY WITHOUT THE QR CODES.
