Proportions are used in many different topics in Geometry. This set of task cards is made up of 7 sets of 5 cards. Each set emphasizes a different application of using proportions in geometry problems.
Set 1: Arc Length
Set 2: Dilations
Set 3: Indirect Measurements
Set 4: Geometric Mean
Set 5: Similar Polygons
Set 6: Proportional Segments
Set 7: Sector Area
This is the identical set of questions used in my Proportions in
Geometry Task Cards, but include the QR Codes for checking the solution.
After students have written their solutions to the questions on the special recording sheet, students can then use a QR reader to scan the QR code. This will take them to a complete solution to the question. If students had difficulty with any part of the question they can use the model solution to learn how to do the problem correctly.
