## Solving One-Step Equations (Greatest Solution)

Directions: Use the digits 1 to 9, at most one time each, to create an equation where x has the greatest possible value. Source: Robert Kaplinsky

## Solving One-Step Equations (Negative and Positive Solutions)

Directions: Use the digits 1 to 9, at most one time each, to create two equations: one where x has a positive value and one where x has a negative value. Source: Robert Kaplinsky

## Creating Inequalities

Directions: Using the integers -4 to 4 at most one time each, create an inequality with solutions of x > 2/3. Source: Robert Kaplinsky

## Two-Step Equations 3

Directions: Use the whole numbers 1 through 9 only one time each to find the largest (or smallest) possible values for the sum of x and y. Source: Erick Lee
