  3. What is an equation? An equation is any number sentence with an equal sign (=). Equations should also balance or be equal on both sides of the equal sign.

  4. The word variable will be used in this presentation. What is a variable? A variable is a letter, shape, or object that represents a number.

  5. Find the missing addend (variable) + 4 = 10 10 – 4 = 6 THINK Use a related subtraction fact = 6

  6. Find the missing addend (variable) 11 – 6 = 5 THINK = 5 6 + = 9 + 2 6 + = 11

  7. What number should be put where the triangle ( ) is to make the number sentence true? + 3 = 8 A11B8 C3D5

  8. What number would balance this equation? 2 + 7 = 4 + A9 B13 C5D3

  9. What number would make this equation equal? + 12 = 9 + 6 A3 B15 C6D12

  10. There are many ways to make a number. Here are some ways to make the number 7 6 + 1 10 - 3 7 + 0 9 - 2 7 - 0 5 + 2 8 - 1 4 + 3

  11. When equations are equal they have the same answer. Here are some equations that are equal. 2 + 7 = 6 + 3 8 + 1 9 + 0 10 - 1 9 - 0 5 + 4 11- 2 7 + 2

  12. Which equation means is NOT equal to and does NOT balance with the equation 4 + 2 A5 + 1 B6 - 0 C3 + 3D4 - 2

  13. Which set below represents 50? A B C D
