Colouring by Trig Ratios, Happy Tears Emoji (Solo Mosaic)
Students use SohCahToa to solve for sides and angles, then use their answers to colour-by-number and reveal the pixel emoji

◾ .docx and .pdf files in a zip folder of the worksheet & emoji colouring grid
◾ The worksheet involves 6 solve-for-side problems and 6 solve-for-angle problems, randomly requiring sin, cos, or tan.
◾ A randomized list of answers at the bottom, allowing for student self-assessment
◾ Complete Answer Key (in order!) for the teacher, showing the numeric solution for each problem.
◾ Handy formulas & steps exemplar included in the handout for students' reference

If you like this product, be sure the check out my collaborative math mosaics, where each worksheet represents a small piece of the larger whole-class mosaic!

The student buy-in factor is HUGE with these worksheets

Encourage students to check their answers by finding them in the randomized list on their worksheet before they colour each square.

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!!
