What Are Multiples of 10?
Multiples of 10 are numbers that end with a zero!
They're like counting by 10s: 10, 20, 30, 40, 50, and so on. When we add these numbers together, we're just adding how many tens we have in total.
How to Add Multiples of 10
1️⃣ Look at the tens place (the first digit)
2️⃣ Add just those numbers together
3️⃣ Put a zero at the end of your answer
Let's Practice Together!
Example 1: 30 + 40
30
+
40
=
?
1. Look at the tens: 3 (from 30) and 4 (from 40)
2. Add them: 3 + 4 = 7
3. Add a zero: 70
🎉 30 + 40 = 70 🎉
Example 2: 50 + 20
50
+
20
=
?
1. Look at the tens: 5 (from 50) and 2 (from 20)
2. Add them: 5 + 2 = 7
3. Add a zero: 70
🌈 50 + 20 = 70 🌈
Parent Tips 🌟
- Use physical objects: Count groups of 10 items (like 10 blocks or 10 coins) to help visualize adding tens.
- Make it a game: Create a "race to 100" where you take turns adding multiples of 10 to reach the target.
- Connect to real life: Point out multiples of 10 in everyday situations like counting dimes (10 cents each) or packages of 10 items.
