Colouring by Percent Problems- Homer Simpson, Solo Math Mosaic
Students solve problems involving percent increase or decrease, such as after-tax costs, sales prices, discounts, depreciation of value, retail mark-up, population growth, inflation, etc.

They use their answers to decode the colour-key, allowing them to colour in the mystery mosaic of Homer Simpson. The colouring is a fun reward for all the hard work, and a motivating factor to get students to complete a page of problems!

INCLUDED (.pdf and .docx everything):
--> 3 different question sets with corresponding mosaics
--> Teaching Tips page with advice on teaching percentages
--> Answer keys for all versions (included in the Teaching Tips file) providing the numeric solutions for all problems

--> All versions have 12 problems. The first 6 involve percent increase, while the last 6 involve percent decrease
--> Each worksheet contains a randomized answer list at the bottom allowing students to check their answers before colouring. (self assessment)
--> Problems include (randomly) both cases where the students are asked to find the new amount after applying a percent increase or decrease, as well as problems where students are given the increased or decreased amount and asked for the original amount.

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

All my colouring worksheets use standard pencil-crayon colours found in the Crayola 24 pack. Perhaps a class set of pencil crayons would be a fun math department investment!

Feedback, suggestions, and frontline stories are always welcomed!
Common Core connection: 7.EE.B.3, and 7.RP.A.3
