What Are Addition Sentences?

Addition sentences are like math puzzles where some numbers are missing!
They look like this: ___ + ___ = ___ or 12 + ___ = 20. Your job is to find the missing numbers to make the addition correct. It's like being a math detective!

How to Solve Addition Sentences

1️⃣ Look at the problem - What numbers do you already know?

2️⃣ Find what's missing - Is it the first number, second number, or the total?

3️⃣ Solve it! - Use counting, number lines, or your addition facts to find the answer

Let's Practice Together!

Parent Tips 🌟

  • Use real objects like buttons or cereal to make addition sentences come to life. "If I have 10 Cheerios and add 5 more, how many do I have?"
  • Play missing number games in the car: "I'm thinking of a number that when added to 8 makes 15. What is it?"
  • Celebrate mistakes as learning opportunities. If your child gets it wrong, say "Great try! Let's figure out why together."
