### Description

A highly engaging task combining individual accountability with collaborative motivation! Colouring meets Trigonometry in this class-wide math mosaic that will look spectacular hanging up in your classroom :) Each worksheet represents a small section of the big picture!

CHECK OUT THE PRODUCT PREVIEW to see the range of problem types, and to know exactly what these worksheets involve!

INVOLVES:
◾3 Sine Law solving for side
◾3 Cosine Law solving for side
◾3 Sine Law solving for angle
◾3 Cosine Law solving for angle

It's simple! Students...
2. Colour the squares.
3. Cut out their section.
4. Combine with the class!

Students complete the math problems, colouring each square according to the colour legend (i.e "Blue: 2 ≤ x < 7"). When the work is done, the coloured sheets are put together to reveal a math mosaic (the “cute” triangle).

PRODUCT INCLUDES (.pdf and .docx file versions in zip folder):
◾Class sets of 18 and 30 unique worksheets.
◾Each worksheet contains 12 acute trigonometry problems requiring the sine or cosine laws to solve for unknown angles and sides.
◾Master Answer Keys for both class sizes, showing the colour and numeric answer for all worksheets (Use this to help you assemble the big picture!)
◾Extra template handout for students to show their work

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!

Imagine if your students were the ones policing homework completion? "Common Jimmy! 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 "Colouring by..." worksheets use standard pencil crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match and encouraged quality colouring! Perhaps a class set of pencil crayons would be a fun math department investment!

If your class size doesn’t line up to 18 or 30, no worries! You could make two 'teams' and have a colouring contest! Or, you could just hand some duplicate worksheets out and decide which to display in the big picture once they're coloured. Or have students work together on a 'practice' sheet, then complete one independently. In my experience, students were eager to do additional sheets to complete the picture!

I’d love and appreciate any feedback, suggestions, and frontline stories you can share!!

Thanks for checking this out!
