Topic Overview

Definitive Answer: Students will fluently subtract two- and three-digit numbers, using strategies based on place value and properties of operations. This includes regrouping.

Hey mathematicians! Today we're going to explore **subtraction**, which means taking away one number from another. It helps us figure out how much is **left** after something is removed. We'll focus on subtracting 2-digit numbers, like when you have 45 stickers and give 12 away. When we subtract 2-digit numbers, we use **place value**. This means we look at the 'ones' place and the 'tens' place. Always start by subtracting the ones digits, then subtract the tens digits. It's like taking away small groups first, then bigger groups!

Step-by-Step Examples

Example 1: A farmer planted 79 apple trees. By the end of the season, 31 trees had not produced any apples. How many apple trees produced apples?
  1. **1. Set it up:** Write 79 above 31, making sure the ones digits (9 and 1) and tens digits (7 and 3) are lined up. ``` 79 - 31 ----
  2. **2. Subtract the ones:** Start with the ones place. 9 ones - 1 one = 8 ones. Write '8' in the ones place of your answer. ``` 79 - 31 ---- 8
  3. **3. Subtract the tens:** Now move to the tens place. 7 tens - 3 tens = 4 tens. Write '4' in the tens place of your answer. ``` 79 - 31 ---- 48
✓ Answer: 48 trees
Example 2: There were 95 birds on a wire. 42 birds flew away. How many birds are left on the wire?
  1. **1. Set it up:** Write 95 above 42, lining up the ones and tens digits carefully. ``` 95 - 42 ----
  2. **2. Subtract the ones:** Begin with the ones place. 5 ones - 2 ones = 3 ones. Put '3' in the ones place of your answer. ``` 95 - 42 ---- 3
  3. **3. Subtract the tens:** Next, subtract the tens. 9 tens - 4 tens = 5 tens. Write '5' in the tens place of your answer. ``` 95 - 42 ---- 53
✓ Answer: 53 birds

Tips & Tricks

  • Think of it like money! If you have 79 and spend 31, you first figure out how many dollars (ones) you have left, then how many tens you have left. Subtracting each place value separately makes it easy!
