1. Third Quarter
Tr. Dhen

2. Objectives:
Subtract 3- to 4-digit numbers from 3- to 4-digit
numbers with regrouping

3. Subtract the following:
2 696
- 584

76 155

4. Lesson 1:
Subtraction With
Regrouping

5. Let Us
Remember
▪ In subtraction, you regroup when a digit in the give
place value in the minuend is smaller than the digit
in the same place value in the subtrahend.
✔ Begin subtracting from the ones, then the tens, the hundreds,
and so on up to the leftmost place value.
✔ You can check if the answer is correct by adding the
difference and the subtrahend to see if you get the
minuend.

6. Gab has 15 gumbles, and he gave 3 to his
