You’ve uploaded a math worksheet titled
“Subtracting 4 digits” that uses
place value charts (Th, H, T, O) with colored dots to visually represent numbers and help solve subtraction problems.
Each problem shows two 4-digit numbers represented by:
-
Green dots = Thousands
-
Red dots = Hundreds
-
Blue dots = Tens
-
Yellow dots = Ones
The task is to
subtract the second number from the first, using the visual aid of removing dots (or imagining removal) and then writing the answer.
Let’s solve each problem step-by-step:
---
Problem 1: 7,345 – 134 = ?
Visual representation:
- First number: 7 Th (green), 3 H (red), 4 T (blue), 5 O (yellow)
- Second number: 0 Th, 1 H, 3 T, 4 O → remove 1 red, 3 blue, 4 yellow
Subtract:
- Thousands: 7 – 0 =
7
- Hundreds: 3 – 1 =
2
- Tens: 4 – 3 =
1
- Ones: 5 – 4 =
1
✔ Answer: 7,211

Problem 2: 5,125 – 2,014 = ?
Visual:
- First: 5 Th, 1 H, 2 T, 5 O
- Subtract: 2 Th, 0 H, 1 T, 4 O → remove 2 green, 1 blue, 4 yellow
Subtract:
- Thousands: 5 – 2 =
3
- Hundreds: 1 – 0 =
1
- Tens: 2 – 1 =
1
- Ones: 5 – 4 =
1
✔ Answer: 3,111

Problem 3: 9,674 – 6,362 = ?
Visual:
- First: 9 Th, 6 H, 7 T, 4 O
- Subtract: 6 Th, 3 H, 6 T, 2 O
Subtract:
- Thousands: 9 – 6 =
3
- Hundreds: 6 – 3 =
3
- Tens: 7 – 6 =
1
- Ones: 4 – 2 =
2
✔ Answer: 3,312

Problem 4: 6,219 – 1,104 = ?
Visual:
- First: 6 Th, 2 H, 1 T, 9 O
- Subtract: 1 Th, 1 H, 0 T, 4 O
Subtract:
- Thousands: 6 – 1 =
5
- Hundreds: 2 – 1 =
1
- Tens: 1 – 0 =
1
- Ones: 9 – 4 =
5
✔ Answer: 5,115

Problem 5: 4,804 – 2,300 = ?
Visual:
- First: 4 Th, 8 H, 0 T, 4 O
- Subtract: 2 Th, 3 H, 0 T, 0 O
Subtract:
- Thousands: 4 – 2 =
2
- Hundreds: 8 – 3 =
5
- Tens: 0 – 0 =
0
- Ones: 4 – 0 =
4
✔ Answer: 2,504
---
Problem 6: 8,907 – 2,543 = ?
Visual:
- First: 8 Th, 9 H, 0 T, 7 O
- Subtract: 2 Th, 5 H, 4 T, 3 O
⚠️
Note: We have
0 tens, but need to subtract 4 tens → we must
borrow!
Step-by-step borrowing:
- Ones: 7 – 3 =
4
- Tens: Can’t do 0 – 4 → borrow 1 from hundreds.
- Hundreds: 9 becomes 8
- Tens: 0 becomes 10 → 10 – 4 =
6
- Hundreds: 8 – 5 =
3
- Thousands: 8 – 2 =
6
✔ Answer: 6,364

## 💡 Teaching Tip:
This worksheet helps students visualize subtraction by physically “removing” place-value units. It reinforces understanding of
place value and
regrouping/borrowing — especially important in Problem 6 where you must borrow from hundreds to tens.
Great for building foundational arithmetic skills! 🎯
Parent Tip: Review the logic above to help your child master the concept of subtraction worksheet with counters.
