Students choose the best method (factorise, quadratic formula, isolating x directly from vertex form...) to solve 12 quadratic equations. This provides some basic practice for students. The picture is a bit of a downer... a sad face. I made this for my students after marking some disappointing tests, recognizing that many needed more practice!

The way the task works is: Students solve for the roots of the quadratic and use the "greater" or "lessor" root as indicated to decode the colour-by-number grid.
i.e. Blue = lessor root of x^2 + 3x + 2 which is (x+2)(x+1) and has roots -2 and -1, so the "lessor root" would be -2. The student would colour all the squares blue that have -2 inside.

The method I had in mind for each question is:
1) simple factorable
3) simple factorable, common factor
4) simple factorable
5) complex factorable
7) simple factorable
8) complex factorable
9) simple factorable
11) vertex form, a value not 1, integer answer
12) vertex form, a value =1, decimal answer
