Topic Overview

Definitive Answer: Students will fluently add and subtract multi-digit whole numbers using the standard algorithm, building upon prior grade-level skills.

Hey there, future math master! Today, we're going to sharpen your skills with 3-digit numbers using a super helpful tool called the **standard algorithm**. This is just a fancy name for a step-by-step method where we line up numbers by their place value (ones, tens, hundreds) to add or subtract. When we add and the sum in a column is 10 or more, we use **regrouping** (like carrying over) to the next place value. When subtracting, if a digit is too small, we also use regrouping (like borrowing) from the next place. This helps us find the **sum** (answer to addition) or difference (answer to subtraction) quickly and accurately!

Step-by-Step Examples

Example 1: What is the sum of 345 and 567?
  1. Line up 345 and 567 vertically, aligning the ones, tens, and hundreds places.
  2. Add the ones column: 5 + 7 = 12. Write down 2 in the ones place and regroup (carry over) 1 to the tens column.
  3. Add the tens column, including the regrouped 1: 1 + 4 + 6 = 11. Write down 1 in the tens place and regroup (carry over) 1 to the hundreds column.
  4. Add the hundreds column, including the regrouped 1: 1 + 3 + 5 = 9. Write down 9 in the hundreds place.
✓ Answer: 912
Example 2: Sarah had 725 stickers. She gave 289 stickers to her friend. How many stickers does Sarah have left?
  1. Line up 725 and 289 vertically, aligning the ones, tens, and hundreds places.
  2. Subtract the ones column: You can't take 9 from 5. Regroup (borrow) 1 ten from the tens place (2 becomes 1), making the 5 into 15. Now, 15 - 9 = 6. Write down 6 in the ones place.
  3. Subtract the tens column: You now have 1 ten and need to subtract 8 tens. You can't take 8 from 1. Regroup (borrow) 1 hundred from the hundreds place (7 becomes 6), making the 1 ten into 11 tens. Now, 11 - 8 = 3. Write down 3 in the tens place.
  4. Subtract the hundreds column: You now have 6 hundreds and need to subtract 2 hundreds. 6 - 2 = 4. Write down 4 in the hundreds place.
✓ Answer: 436 stickers

Tips & Tricks

  • Always start with the ones place! Think of it like building a tower: you start from the bottom, not the top. This helps you handle regrouping correctly every time.
