What Does It Mean to Subtract Tens?
Subtracting tens is like taking away whole groups of ten!
When we subtract tens, we're working with numbers like 10, 20, 30, and so on. It's just like counting backwards by tens!
How to Subtract Tens
1️⃣ Look at the first number (how many tens you start with)
2️⃣ Subtract the second number (how many tens you're taking away)
3️⃣ Count what's left - that's your answer!
Let's Practice Together!
Example 1: 50 - 20
50
20
?
Let's count backwards by tens: 50...40...30!
Example 2: 80 - 40
80
40
?
Use your fingers to count: 80 - 10 = 70, 70 - 10 = 60, 60 - 10 = 50, 50 - 10 = 40!
Parent Tips 🌟
- Use physical objects like blocks or coins grouped in tens to make subtraction visual and hands-on
- Practice counting backwards by tens during everyday activities (like counting down stairs)
- Make it a game - see how many subtraction problems your child can solve in one minute!
