Harness the motivating power of collaboration while maintaining individual accountability! Every student’s worksheet is different! Students use their answers to colour-by-number their section of the larger whole-class mosaic! The end result looks great on your wall, and your students will be proud! Whether you are teaching positive/negative rational values for the first time, or need a fun review of the basics, this task offers an engaging way to get TONS of practice out of your students.

You can also get "Colouring Superman by Signed Decimals (+ - × ÷)"

And... Superman by Integer ADDITION and SUBTRACTION" and "Batman by Integer MULTIPLICATION and DIVISION" if you don't want decimals, or wanted to separate + - from × ÷

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

◾ Both.pdf and editable .docx format
◾ Full class set of 36 worksheets (Every single sheet is unique!) that combine to create the Batman mosaic
◾ All worksheets contain 84 integer problems involving + - × ÷ of positive and negative decimal numbers.
◾ Complete answer key / mosaic guide provided, giving the numeric answers and colour answers for all worksheets.
◾ Teaching Tips page for smooth implementation in your class (Find this in the answer key file)

If you like this product, be sure the check out the whole Collaborative Math Mosaic directory, sorted by topic!

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 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...). Perhaps a class set of pencil crayons would be a fun math department investment!

Feedback, suggestions, and frontline stories are always welcomed!
