Graph inequalities

Target: Match an inequality to an open circle and a direction.

Language target: Describe the circle and the arrow.

Likely miss: Students shade toward the smaller numbers for a greater-than inequality, or they fill the boundary circle.

Ask: Which test point makes the inequality true?

If you see it: Test a number in the shaded region before accepting the graph.

Evidence to listen for: The student matches the open or closed circle to the sign and shades the true side.

Next: Have the student test one point on each side aloud.

Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
