Highly Engaging! My students volunteer to complete extra sheets!

Each worksheet represents a small section of the big picture! The end result will look spectacular hanging up in your classroom :)
CHECK OUT THE PRODUCT PREVIEW to see the range of problem types, and to know exactly what these worksheets involve!

The Lazy Giraffe mosaic is also available in an Annuities version, where students solve problems involving present and future value, and interest earned and paid.

Students use the Pythagorean Theorem to solve various problems involving right triangles, then use the answers to colour their worksheets based on the colour key. This is 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!

INCLUDED (.pdf and .docx files in zip folder):
--> Full class set of 25 and 16 worksheets (all different!) that combine to create the Lazy Giraffe mosaic.
-->Worksheets involve a range problems that involve solving for the hypotenuse or a leg of the triangle.
--> Master Answer Key showing the colour and numeric answer range for each colour for all worksheet problems.

Teaching Tip: Have students draw a right triangle and label the given information as they read each problem.

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!

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!

If your class size doesn’t line up with 16 or 25, no worries! You could hand out some duplicate worksheets (if you have more students) and decide which to display in the big picture once they're coloured. Or, you could have some students work pairs (differentiated learning!). If you’re under 16 students, in my experience, students are eager to do additional sheets to complete the picture! (Or you could use the answer key to fill in the missing pieces quickly)

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

Thanks for checking this out!
