About this worksheet

Testing values in equations. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can put a number in for x and tell whether the equation is true.
  • I can find which value from a list makes x + 5 = 13 or 4x = 28 true.
  • I can tell that a number at the edge of an inequality, like 5 in x + 4 > 9, does not make it true.

Standard: 6.EE.B.5

Words to know

substitute: Put a number in place of the letter.

solution: A number that makes the equation or inequality true.

equation: A math sentence with an equal sign. Both sides have the same value.

inequality: A math sentence with > or <. One side is greater or less than the other.

true: Both sides match for an equation, or the comparison really holds for an inequality.

bar (tape) diagram: A bar cut into parts that shows how the numbers fit together.

Common mistakes

Your child used the same operation the equation shows instead of undoing it, so x + 6 = 15 gave 21. Try putting their value into the equation and asking whether both sides match.

Your child subtracted the number next to the letter, so 4x = 36 gave 32. Try asking "4 groups of what make 36?" and let them draw the groups.

Your child added the number next to the letter instead of multiplying, so 5x with x = 3 became 5 + 3. Try asking "what is 5 groups of 3?" and let them draw the groups.

Questions parents ask
