Cylinders, Cones, and Spheres
Each Eighth Grade Math task card contains a question relating to the volume of a three-dimensional object. A picture of the related volume is on each card (cylinder, cone, sphere).
Quick Response (QR) codes can add a new layer of fun to the classroom. These print very nicely in grey scale and in black and white.
You can see exactly what you get in the PREVIEW!
You have many options with this set. You can post the answers around the room to make it even more fun! Each QR code contains the answer to the question and in addition a positive comment such as “Congratulations!”, “Way to Go!” and “Awesome!”.
If you choose not to make use of the QR codes, you can use the answer sheet provided to check answers. The answer sheet will be a very useful tool as it provides answers in 4 different ways. You could also have the students solve the problems using more than one method to show them the differences in accuracy.
