Absolute Value Equations - Picking Mushrooms (Matching Game)

In this 18 questions - matching game, students will solve absolute value equations of four types

▸ ∣ax + b∣ = c, c ≧0 ( eleven problems)
▸ ∣ax + b∣ = cx + d ( three problems)
▸ ∣ax + b∣ = ∣cx + d∣ ( two problems)
▸ m ∣ax + b∣ + n ∣± ax + b∣ = p ( the last two problems)

Activity Directions: Students find the solution to each of the equations. The solution sets are written on 18 of 20 mushrooms. When students arrive at a correct answer, they “pick the mushroom” having this answer written on it. It is said that two mushrooms are “poisonous” – with an incorrect answers written on them . Students have to find them out.

The activity can be used individually, in pairs or in groups of 3.

Student recording sheets and answer keys are included.
