Screw the test point.
My students super struggle with simple Order of Operations and I am expected to cover all this curriculum before their big exam in May. So give me all the shortcuts!
In my first years of teaching, I ran into the “shade under & over” method vs. the “test a point” method. LIFESAVER.
When y is isolated:
If the inequality symbol is a < or ≤ you shade UNDER the line.
If the inequality symbol is a > or ≥ you shade OVER the line.
That just makes sense! No test point required.
So I made this Foldable that can be found HERE!
The foldable includes:
- 4 examples
- 3 examples require y to be isolated
- 2 examples need the inequality symbol to be flipped after dividing by a negative
- An area to choose and discuss possible solutions
