Thank you for visiting my store!
This product contains 36 Task cards on the properties of proportions, as found in a standard high school geometry class. There are six topics all together, and they are grouped on the cards in the following way:
#1 to #6: Solving proportions, including geometry word problems
#7 to #12: Determining similarity of polygons and finding the scale factor
#13 to #18: SAS, SSS and AA Similarity Postulates
#19 to #24: Triangle Proportionality & Midsegment Theorems
#25 to #30: Proportionality of Parallel Lines
#31 to #36: Parts of Similar Triangles (medians, altitudes, etc.)
These task cards have a wide variety of difficulty levels. In general, the last two or three in each group above are the most challenging for that topic. If your students are not up to the challenge, you will want to remove these last cards for each topic.
Task Cards have a many uses. You can use them for:
1. Group work
3. Scavenger Hunt
My favorite way to use them is in groups using whiteboards. Everyone has an individual whiteboard. Each group has one group of the task cards - #1 through #6, #7 through #12, etc. Each student does the task card on their own whiteboard and then they compare answers. They need to agree on an answer (arguing is encouraged)! Once they agree on an answer, it gets recorded on the group’s answer sheet. This way, as I walk around the rom, I can easily check for understanding simply by looking at their sheet.
The borders I used are from Creative Clips on TPT. Thank you, Krista!
