Pythagorean Theorem BTC Thin Slicing Group Activity | Grade 8 Math

This "Thin Slicing" activity on the Pythagorean Theorem gets your 8th grade students thinking about geometry and right triangles. These progressively challenging task cards start students with simple equations with square roots and right triangles and progress up to multi-step problem solving with real-world scenarios. Students must work together to find missing sides of a right triangle, work with triangles in 3 dimensions, and problem solve real-world tasks.

Great as a review activity at the end of a Pythagorean Theorem unit, or a challenging task after your students have learned all of the basics.

This lesson with printable task cards uses Building Thinking Classrooms strategies for teaching math created by Peter Liljedahl. If you have been looking to implement the Building Thinking Classrooms model of instruction, but don't know where to start, this is a great resource for you.
