Why Teach 2-Digit and 3-Digit Addition and Subtraction?
You might be wondering, why is it so important to learn 2-digit and 3-digit addition and subtraction? 🤔 These skills are the foundation for higher math. They help kids think logically and solve problems. Plus, math is something we use every day, like figuring out how much to tip at a restaurant or calculating how much a sale saves us. 🛒💸
Understanding Addition and Subtraction
Before we go over more examples, let’s talk about the parts of an addition or subtraction problem.
Parts of an Addition Problem:
- Addends: The numbers you are adding.
- Plus Sign (+): Shows that you’re adding.
- Equal Sign (=): Shows that both sides are the same.
- Sum: The result of adding.
Example:
23 + 17 = 40 - 23 and 17 are the addends.
- The sum is 40.
Parts of a Subtraction Problem:
- Minuend: The number you start with.
- Subtrahend: The number you take away.
- Equal Sign (=): Shows that both sides are the same.
- Difference: The result of subtracting.
Example:
45 - 12 = 33 - 45 is the minuend.
- 33 is the difference.
Exploring Properties with Examples
Identity Property of Addition: Adding 0 to any number keeps it the same. Example: 67 + 0 = 67
Commutative Property of Addition: The order of numbers doesn’t change the answer. Example: 34 + 56 = 56 + 34 = 90
Associative Property of Addition: How you group numbers doesn’t change the answer.
Example: (12 + 34) + 56 = 12 + (34 + 56) = 102
Addition and Subtraction With and Without Regrouping
Addition with Regrouping: When the sum of a column is greater than 9, we “carry over” to the next column.
Example: 368 + 475 = 843
Subtraction with Regrouping: When a digit in the top number is smaller than the digit in the bottom number, we “borrow” from the next column. Example:514 - 289 = 225
Addition without Regrouping: When the sum is less than 10, no regrouping is needed. Example:123 + 456 = 579
Subtraction without Regrouping: When the top number is larger than the bottom number, no regrouping is needed.
Example: 678 - 123 = 555
