Colouring by Circle Area & Perimeter, Pi (25 Sheet Mosaic)

Highly Engaging! Students work independently on their own worksheet, yet collaboratively create a whole-class Pi mosaic when the work is all done!

Involves both diagram problems, and a variety of application word problems!

Every worksheet has a unique set of problems, yet follows the same order of problem-type! You can confidently have students work together without cheating. Expect to hear good peer-to-peer math conversation and teaching.

• pdf and docx file versions of the class set of 25 worksheets
• Complete answer key giving the colour and numeric answer for all problems on every worksheet
• Students' worksheets have a randomized answer list at the bottom so they can monitor their own understanding.
• A Teaching Tips page, for smooth implementation of this task

The student buy-in factor is HUGE with these worksheets

Encourage students to check their answers by finding them in the randomized list on their worksheet before they colour each square.

All my “Colouring by…” worksheets use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match (and encourage quality colouring!). Perhaps a class set of pencil crayons would be a fun math department investment!

Feedback, suggestions, and frontline stories are much appreciated!!

Thanks for checking this out!
