Model this:
-2x + 4
2x² + x -3
Polynomial Multiplication
(-3x-1) - (4x+2)
(2x²-2x+3) - (3x²+3x-2)
3 + 2x, if x = 4
2x² + 3x - 5, if x = -2
2x - 4 = 8
-x + 4 = 3x -2
3x + 3
4x² + 4x +1
Studies show that students who are instructed using the
Concrete-Representational-Abstract approach:

2. show more motivation and on-task behavior

3. understand mathematical ideas

4. better apply math to life situations
