Colouring by Ratio Applications, Lego Joker (12 Sheet Collaborative Math Mosaic)
Harness the motivation of collaboration coupled with the assurance of individual accountability! Every worksheet contains a different set of problems, yet all worksheets are needed to create the group mosaic.

Learning and fun share a one-to-one ratio in this engaging activity! Students must solve the ratio application word problems, then use their answers to decode their colour-by-number grid. The individual sheets combine to create the Lego Joker mosaic (12 worksheets). You will seem like a magician as you piece the sheets together, and the mosaic will look fantastic in your classroom! :)

Great for a variety of grades!

INCLUDED: (in both .docx and .pdf format)
◾ Full class set of 12 worksheets (all different!) that combine to create the Joker mosaic
◾ Complete answer key, giving the answers for all worksheets (easy assessment!)
◾ Teaching Tips page for smooth implementation in your class
◾ Coloured mosaic guide with coordinates, for easy assembly
◾ Scrambled answers list at the bottom of each student's worksheet, allowing for self-assessment.

It's simple!
1. Calculate the answers.
2. Colour the squares.
3. Cut out your section.
4. Combine with the class!

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!

Leave the heroes 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 collaborative math mosaics use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match, colour darkly, and stick to one colouring medium (i.e. don't mix crayons with markers with pencil crayons...). Note that while every worksheet has a math problem for all the colours, individual colouring-grid sections of the mosaic may only use some of colours. (i.e. the 'background' section).

Feedback, Suggested Improvements, and frontline stories are always welcomed!
