Operations & Algebraic Thinking

Directions: Using the digits 0 through 9, at most one time each, place a digit in each box to create the greatest possible value. Source: Robert Kaplinsky

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: 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? …

Directions: Using the digits 1 to 7, at most one time each, place a digit in each circle so that the sum of the numbers in 3 squares (the middle horizontal line or 2 diagonals) are same. e.g A+B+C or D+B+E or F+B+G Is there more than one solution? Source: Al Oz

Directions: Using the digits 0 to 9 at most one time each, place a digit in each box so that each expression is simplified to a different odd number. Source: Molly Rawding

Directions: Use the digits 0 to 9, only once, to make the inequality true. Source: Laura Wagenman

Directions: Make the largest (or smallest) expression by using the digits 0-9, no more than one time each, in the boxes below.  Note: for 5th grade, remove the exponent to make it grade level appropriate. Source: Robert Kaplinsky with answer from Michael Fenton and his students.
