The student buy-in factor is HUGE with these worksheets; they all want to see the finished picture come together! High school students love colouring too! This sure beats textbook homework!

Imagine if your students were the ones policing homework completion? "Common Jenny! Do your work or we'll have a hole in our picture!"

Leave the picture a secret or show it for motivation… it’s your call.

Encourage students to check their answers by finding them in the randomized list on their worksheet before they colour each square. This will increase the accuracy of the final picture!

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!

If your class size doesn’t line up with 15 or 30, no worries! You could hand out some duplicate worksheets (if you have more) and decide which to display in the big picture once they're coloured. Or, you could have some students work pairs (differentiated learning!). If you have a small class, you could use the answer key to fill in the missing pieces quickly.

Feedback, suggestions, and frontline stories are always welcomed!

Thanks for checking this out! Merry Christmas.
