Each mosaic consists of 12 worksheets (each one unique!) involving sine and cosine law problems for missing sides and angles. Students' sheets combine to create the hero mosaics. The collaborative motivation is huge! The answers are given in a randomized list at the bottom of each sheet, allowing students to monitor their own work. Complete answer keys are provided for you, as well as a Teaching Tips page for smooth implementation!
This product comes in both .pdf and .docx format. All files are included in the zip folder.

The Superman vs Batman battle is also available in the following versions:
◾Fractions - +,-, ×, and ÷ positive mixed fractions
◾Trig Ratios (SohCahToa) - solve for sides and angles
◾Pythagorean Theorem - word problems and life applications
◾Linear Systems - substitution, elimination, and graphing
Students solve the trig problems, then use the answers to colour their worksheets based on the colour key.
1. Calculate the answers.
2. Colour the squares.
3. Cut out your section.
4. Combine with the class!
Both a visual answer key, showing the completed mosaic with labelled coordinates (to help you assemble the picture from the combined worksheets), and a numeric answer key for each individual worksheet are provided for both hero mosaics.
Leave the hero pictures a secret, or let them know their team in advance 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 always welcomed!
COMMON CORE MATH STANDARDS:
Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).
