What Does "Without Regrouping" Mean?
When we add a two-digit number and a one-digit number without regrouping, it means we don't need to carry over any numbers to the tens place!
It's like adding small numbers where the ones place stays happy all by itself. The tens digit doesn't change, and the ones digit just gets a little bigger.
How to Add Without Regrouping
1️⃣ Look at the two-digit number (like 23)
2️⃣ Add the one-digit number to the ones place (like 23 + 4)
3️⃣ Write your answer (23 + 4 = 27)
Let's Practice Together!
Example 1: 34 + 5
Let's break it down:
1. The two-digit number is 34
2. Add 5 to the ones place (4 + 5 = 9)
3. The tens digit stays the same (3)
4. Final answer: 39
Example 2: 62 + 7

Parent Tips 🌟
- Use physical objects: Count buttons, blocks, or candies to make the concept concrete. "If you have 25 candies and get 3 more, how many do you have?"
- Number line practice: Draw a number line and have your child "hop" forward to add the one-digit number.
- Real-world applications: Point out opportunities in daily life - "You have 18 minutes of screen time and earn 2 more, how many is that?"
