First, let’s break it down:
- 2-Digit Numbers: These are numbers that have two digits in them. For example, 12, 34, 56, 78 and so on. The first digit is called the “tens” place because it represents tens, and the second digit is the “ones” place.
- Addition: This is when you put two numbers together to get a bigger number. If you have 5 apples and someone gives you 2 more apples, you now have 7 apples. So, 5 (apples) + 2 (apples) = 7 (apples).
- Subtraction: This is when you take a smaller number away from a bigger number. If you have 8 candies and you eat 3 candies, you are left with 5 candies. So, 8 (candies) – 3 (candies) = 5 (candies).
- Without Regrouping: Sometimes when we add or subtract, we have to “carry” or “borrow” from another place value. This is called “regrouping”. But in this worksheet, you won’t have to do that. The problems are designed so that you won’t have to carry or borrow.
So, if you’re working on a problem like 35 + 24, here’s how you’d solve it:
- Add the numbers in the ones place first: 5 + 4 = 9
- Then add the numbers in the tens place: 30 + 20 = 50
- Put those two answers together: 50 + 9 = 59
If you’re working on a problem like 46 – 21, here’s how you’d solve it:
- Subtract the numbers in the ones place first: 6 – 1 = 5
- Then subtract the numbers in the tens place: 40 – 20 = 20
- Put those two answers together: 20 + 5 = 25
In this worksheet, you’ll be doing lots of problems like these. It’s great practice for getting really good at adding and subtracting 2-digit numbers without regrouping. Remember, practice makes perfect!
