Colouring by Order of Operations, 25 Sheet Math Mosaic

Students are each responsible to complete one section of the mystery mosaic (“Bowser”!). The mosaic consists of twenty-five sections. Students must correctly apply order of operations to evaluate each problem expression (twelve problems per worksheet), and then use their answers to color-by-number. Every single worksheet is different! Students can’t copy, but they can help each other!

The problems use integer values (negative numbers are used, i.e. 5(-3) + 4), and use a random combination of addition, subtraction, multiplication, division, brackets/parentheses, and exponents.

The collaborative goal and mystery image will motivate them to work!


  • Editable Microsoft Word format for all versions
  • Full class set of twenty-five worksheets (Every single sheet is unique!) that combine to create the Bowser mosaic.
  • All worksheets contain twelve order of operations problems
  • A complete answer key are provided, as well as a color key (“Blue = 3 or 4”) for a quick assessment.
  • Teaching Tips page for smooth implementation in your class
  • Scrambled answers are at the bottom of each student’s worksheet so they can self-assess their work and fix their errors.

The student buy-in factor is HUGE with these worksheets; they all want to see the finished picture come together! Leave the picture a secret or show it for motivation - it’s your call.

All my collaborative math mosaics use standard pencil-crayon colors found in the Crayola twenty-four pack. For best results, use the exact color name match, color darkly, and stick to one coloring medium (i.e. don’t mix crayons with markers with pencil crayons…). Perhaps a class set of pencil crayons would be a fun math department investment!

Feedback, suggestions, and front-line stories are always welcomed!
