Complete the addition sentence – sums up to 10

key points :

➕ Addition means putting together!

Example: 🧸 + 🧸 = 🎁 (Two toys make one group of two!)

🔟 We are making sums that add up to 10!

The total (sum) should always be 10. 🎯

💡 Use number pairs that make 10:

  • 0 + 10 = 🔟
  • 1 + 9 = 🔟
  • 2 + 8 = 🔟
  • 3 + 7 = 🔟
  • 4 + 6 = 🔟
  • 5 + 5 = 🔟
  • 6 + 4 = 🔟
  • 7 + 3 = 🔟
  • 8 + 2 = 🔟
  • 9 + 1 = 🔟
  • 10 + 0 = 🔟

🎲 Think of it as finding the missing number!

Example: 7 + ___ = 10 → 🧩 The missing number is 3.

🍎 Use objects or pictures to help!

Count apples 🍏, stars ⭐, or blocks 🧱 to find how many more you need to make 10.

✏️ Try different ways to make 10!

6 + 4 = 10

4 + 6 = 10
(Order doesn’t change the sum! 🔁)

💪 Practice makes perfect!

Play games or sing songs 🎶 that help you remember number pairs that make 10.

🌟 Example Sentences

  • 3 + ___ = 10 → 🧩 7
  • ___ + 8 = 10 → 🧩 2
  • 5 + ___ = 10 → 🧩 5

🎉 Fun Tip:

Use your fingers 🖐️🖐️ to count and make sums of 10.
👉 Example: Show 6 fingers on one hand ✋ and 4 on the other 🤚 — together, you get 10!
