Add three or more one-digit numbers

key notes :

👀 Look at the Numbers Carefully

Identify all the numbers you need to add.

  • Example: 3 + 4 + 2 + 1

➕ Start Adding Step by Step

Add the first two numbers first.

Then add the next number to the sum.

Continue until all numbers are added.

  • Example:
  • 3 + 4 = 7
  • 7 + 2 = 9
  • 9 + 1 = 10 ✅

🎯 Use a Number Line (Optional)

Jump from one number to the next on a number line.

Helps you see the addition visually.

🧠 Make a Group

Group numbers to make 10 if possible (helps with quick adding).

Example: 6 + 4 + 3 → 6 + 4 = 10, then 10 + 3 = 13

✅ Check Your Answer

Add the numbers in a different order to see if you get the same sum.

Example: 3 + 4 + 2 = 3 + 2 + 4 = 9

💡 Tips for Quick Adding

Start with the biggest number.

Look for pairs that make 10.

Use your fingers if needed—no shame in counting! ✋
