**Harness the motivating power of collaboration while maintaining individual accountability!** 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!

(You can get this mosaic bundled with two other Einstein mosaics dealing with trigonometry: click here to go to the bundle)

**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 .docx and .pdf format

◾ full class set 25 worksheets, every sheet unique! The worksheets combine to create the Einstein mosaic

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

◾ Teaching Tips page for smooth implementation in your class

◾ Coloured mosaic guide for easy assembly

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

◾ "Order of Problems" sequence that each worksheet follows

**This makes a great unit summative task! **.

Here's the list of the order of questions each worksheet contains: (Check out the product preview to see sample worksheets and know exactly what this task involves!)

**Problem Order:**

1) determine the axis of symmetry

2) x or y coord. of vertex, any method

3) y-intercept from vertex form

4) solve - simple factorable, with common factor

5) solve for ‘a’ given vertex & point

6) solve - simple factorable

7) quadratic trajectory word problem

8) x or y coord. of vertex, by completing the square

9) solve - complex factorable

10) solve - quadratic formula, exact roots

11) solve - quadratic formula, decimal roots

12) solve - quadratic formula, exact roots

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!

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!**

CCSSHSA-REI.B.4b

Solve quadratic equations by inspection (e.g., for 𝘹² = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as 𝘢 ± 𝘣𝘪 for real numbers 𝘢 and 𝘣.

CCSSHSA-REI.B.4a

Use the method of completing the square to transform any quadratic equation in 𝘹 into an equation of the form (𝘹 – 𝘱)² = 𝘲 that has the same solutions. Derive the quadratic formula from this form.

CCSSHSA-REI.B.4

Solve quadratic equations in one variable.
