Sheet #2036
Fill-in-the-blank equations like 7 + __ = 12 build number sense and are a child's first step toward algebra.
Tips for practicing
- Encourage "counting on": start at 7 and count up to 12.
- Connect addition and subtraction: 7 + __ = 12 is the same as 12 − 7 = __.
- Read the equation out loud as a sentence: "seven plus what makes twelve?"
