Directions: Using the integers -9 to 9, at most one time each, place an integer in each box to make the greatest possible product. Source: Robert Kaplinsky

Directions: Using the integers -9 to 9 at most one time each, place an integer in each box to make two products: one where the product is positive and one where the product is negative. You may reuse all the integers for each product. Source: Robert Kaplinsky in Open Middle Math

Directions: Using the digits 1 to 9, at most one time each, place a digit in each box to create two equations: one where x has a positive value and one where x has a negative value. You may reuse all the digits for each equation. Source: Robert Kaplinsky in Open Middle Math

Directions: Using digits -9 to 9, at most one time each, place a digit in each box to create an inequality that has a solution of x > 2. Source: Sarah Furman
