Colouring by Trig Ratios from Triangle Diagrams, The Grinch (15 & 30 Worksheet Mosaics)
Highly Engaging! Multiple versions and class sizes included to accommodate your class situation. May your students' trig abilities grow two whole sizes bigger this year!
Each worksheet represents a small section of the big picture! The end result will look spectacular hanging up in your classroom :)

Students use the basic trig ratios (sin, cos, tan) to solve for sides and angles, then use the answers to colour their worksheets based on the colour key. So much cooler than textbook homework!

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

--> Full class set of 30 colour-by-range style worksheets
--> Full class sets of 15 and 30 colour-by-number style worksheets (These have fewer problems per worksheet than the colour-by-range style, for a lighter assignment)
-->Worksheets involve a range of right trigonometry problems that involve choosing and applying the correct primary trig ratio to solve for an unknown side or angle.
--> Every worksheet is unique, and contains a randomized list of answers at the bottom, allowing for student self-assessment
--> Master Answer Key showing numeric solution for all worksheets
--> Completed and Coloured mosaic guide with coordinates to help you assemble the finished product

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 Josh! 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!

Feedback, suggestions, and frontline stories are much appreciated!!
