The image shows a subtraction game board titled
"Don't Lose the Treasure", which involves subtraction with regrouping. The goal of the game is to navigate from the
Start space to the
End space by solving subtraction problems along the way.
Problem Analysis:
The task likely involves solving one or more subtraction problems on the board. Since the specific problem isn't explicitly stated in the image, I'll explain how to solve a general subtraction problem with regrouping using an example from the board.
Example Subtraction Problem:
Let's take one of the subtraction problems visible on the board:
609 - 356.
Step-by-Step Solution:
1.
Write the numbers vertically:
```
609
- 356
```
2.
Subtract the ones place:
- You need to subtract \( 9 - 6 \).
- \( 9 - 6 = 3 \).
- Write 3 in the ones place of the answer.
```
609
- 356
---
3
```
3.
Subtract the tens place:
- You need to subtract \( 0 - 5 \).
- Since 0 is less than 5, you need to
regroup (borrow) from the hundreds place.
- Borrow 1 from the hundreds place (6 becomes 5), and add 10 to the tens place (0 becomes 10).
- Now, subtract \( 10 - 5 \).
- \( 10 - 5 = 5 \).
- Write 5 in the tens place of the answer.
```
5[10]9
- 3 5 6
------
5 3
```
4.
Subtract the hundreds place:
- After borrowing, the hundreds place is now 5.
- Subtract \( 5 - 3 \).
- \( 5 - 3 = 2 \).
- Write 2 in the hundreds place of the answer.
```
5[10]9
- 3 5 6
------
253
```
Final Answer:
The result of \( 609 - 356 \) is
253.
General Explanation:
-
Regrouping (or borrowing) is used when the digit in the minuend (top number) is smaller than the corresponding digit in the subtrahend (bottom number).
- Always start from the rightmost digit (ones place) and move leftward.
- If regrouping is needed, borrow 1 from the next higher place value and adjust accordingly.
Conclusion:
This game helps practice subtraction with regrouping in a fun and interactive way. Each space on the board represents a subtraction problem that players must solve to progress.
If you have a specific problem from the board you'd like me to solve, please let me know! Otherwise, the method above can be applied to any subtraction problem on the board.
Final Answer: \(\boxed{253}\) for the example problem \(609 - 356\).
Parent Tip: Review the logic above to help your child master the concept of interactive 3 digit subtraction.
