- These mosaics are a great way to involve every learner in your class! They provide collaborative motivation through a common goal, while upholding individual accountability since every worksheet has different problems.$44.95$75.55Save $30.60

### Description

**Harness the motivating power of collaboration while maintaining individual accountability!**This activity will stand out from anything you’ve tried before! Every student’s worksheet is different, yet similar in the type of problems asked. When students answer all the math problems, they use their answers to colour-by-number their small section of the larger mosaic! The end result looks great on your wall, and your students will be proud!

**This task makes a great summative assessment**, or prerequisite review before moving on with trig. Four mosaic sizes are included for flexibility in class size!

**IT’S SIMPLE!**

1. Calculate the answers.

2. Colour the squares.

3. Cut out your section.

4. Combine with the class!

**INCLUDED:**

◾ Everything comes in both.pdf and editable .docx format

◾ Full class sets of 12, 20, 24, and 36 worksheets (Every single sheet is unique!). Each set’s sheets combine to create the Black Panther mosaic

◾ All worksheets contain 12 similar triangle problems, regardless of the mosaic size.

◾ "Order of Problems" sequence that each worksheet follows

◾ Printable “show calculations” sheet where students can show their work, keeping things organized for you to assess!

◾ Complete answer keys, giving the numeric answers for all worksheets (easy assessment!)

◾ Colour-Range answer key for quick assessment. e.g. All sky blue questions have an answer within [36, 44)

◾ Handy Teaching Tips page for smooth implementation in your class

◾ Coloured mosaic to guide the image assembly

◾ Scrambled answers are listed at the bottom of each student's worksheet, allowing for self assessment.

◾ A special little extra… a QR code at the bottom of students’ worksheets linking to a ridiculous youtube math rap I made about similar triangles. I’m they AND you will get a kick out of it

**This makes a great unit summative task, or prerequisite review before moving on with trig**

**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! Leave the picture a secret or show it for motivation… it’s your call.

Encourage students to check all their answers by finding them in the scrambled list at the bottom of their worksheet

**before**they colour. This will increase the accuracy of the final picture!

All my collaborative math mosaics use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match, colour darkly, and stick to one colouring medium (i.e. don't mix crayons with markers with pencil crayons...). Perhaps a class set of pencil crayons would be a fun math department investment!

**Feedback, suggestions, and frontline stories are always welcomed!**

**Common Core – High School Geometry: Similarity, Right Triangles, & Trigonometry**

A.2 Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides.

B.5Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
