Review tiers 1–10

Checklists are parent-judged.
Written items: verify against practice set patterns.
Standard text: Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x2 + y2 = 3.
