Directions: Using the digits 0 through 9, at most one time each, place a digit in each box to create two true statements: one where the value on each side of the equal sign is greater than 30 and one where it’s less than 30. You may reuse all the digits for each equation. Source: Robert Kaplinsky

Directions: Using the digits 1-9 only once, create two factors that will result in a product as close to 10,000, without going over. Source: Danielle McNichol

Directions: Use the operation symbols (+, -, x, ÷) and equal sign (=) to make a true equation. Operation symbols may be used more than once. What is the least value for each part of the equation? What is the greatest value for each part of the equation? Can you complete the equation with at least one of each symbol? …
