Step-by-step solution for: Multiplication by 12s (Worksheets)
Let’s solve each part of the worksheet step by step.
---
Part 1: Skip count by 12s
We start at 0 and add 12 each time until we reach 120.
0 → 12 → 24 → 36 → 48 → 60 → 72 → 84 → 96 → 108 → 120
Check:
12 × 1 = 12
12 × 2 = 24
12 × 3 = 36
12 × 4 = 48
12 × 5 = 60
12 × 6 = 72
12 × 7 = 84
12 × 8 = 96
12 × 9 = 108
12 × 10 = 120 ✔
So the missing numbers are:
24, 36, 48, 60, 72, 84, 96, 108
---
Part 2: Complete the multiplication table for 12
We multiply 12 by each number in the top row:
Top row: 3, 10, 5, 4, 1, 2, 6, 7, 0, 9, 8
Calculate:
- 12 × 3 = 36
- 12 × 10 = 120
- 12 × 5 = 60
- 12 × 4 = 48
- 12 × 1 = 12
- 12 × 2 = 24
- 12 × 6 = 72
- 12 × 7 = 84
- 12 × 0 = 0
- 12 × 9 = 108
- 12 × 8 = 96
So the answers in order:
36, 120, 60, 48, 12, 24, 72, 84, 0, 108, 96
---
Part 3: Write the missing factors
We need to find what number multiplied by 12 (or another number) gives the product.
1. 12 × ___ = 108 → 108 ÷ 12 = 9
2. 12 × ___ = 96 → 96 ÷ 12 = 8
3. ___ × 5 = 60 → 60 ÷ 5 = 12
4. ___ × 12 = 24 → 24 ÷ 12 = 2
5. 12 × ___ = 36 → 36 ÷ 12 = 3
6. 6 × ___ = 72 → 72 ÷ 6 = 12
Answers:
9, 8, 12, 2, 3, 12
---
Part 4: Compare using <, >, or =
We calculate both sides and compare.
1. 3 × 12 ___ 36
→ 36 ___ 36 → =
2. 45 ___ 4 × 12
→ 45 ___ 48 → <
3. 12 × 4 ___ 5 × 12
→ 48 ___ 60 → <
4. 0 × 12 ___ 12
→ 0 ___ 12 → <
Answers:
= , < , < , <

Part 5: Complete the multiplication wheel
The center is “12x”, so we multiply 12 by each number around the wheel.
Numbers around the wheel: 3, 7, 8, 0, 6, 1, 9, 4 (going clockwise from top)
Wait — let’s list them as shown in the image description (from the user's upload):
Looking at the wheel: it has outer numbers: 3, 7, 8, 0, 6, 1, 9, 4 — but arranged in a circle. The inner ring should be 12 × that number.
Actually, looking at standard multiplication wheels like this, the outer numbers are the multipliers, and you write the product inside the corresponding segment.
But in the diagram described, there’s an inner ring with some numbers already filled? Wait — the user wrote:
“Complete the multiplication wheel.” and shows a wheel with center “12x” and outer numbers: 3, 7, 8, 0, 6, 1, 9, 4 — and some inner numbers given: 36, 84, 72, 0, 12, 108, 48 — wait, actually, let me reconstruct based on typical layout.
Actually, from the text: “Complete the multiplication wheel.” and the wheel has:
Outer ring (multipliers): probably 3, 7, 8, 0, 6, 1, 9, 4 — but let’s match the products given.
In the wheel, some products are already written: 36, 84, 72, 0, 12, 108, 48 — and one missing? Or maybe all except one?
Wait — the user says: “Complete the multiplication wheel.” and lists:
Center: 12x
Outer numbers (clockwise from top?): 3, 7, 8, 0, 6, 1, 9, 4
Inner products shown: 36 (for 3), 84 (for 7), ? (for 8), 0 (for 0), ? (for 6), 12 (for 1), 108 (for 9), 48 (for 4)
Wait — let’s assign:
If outer number is N, inner product is 12 × N.
So:
- 3 → 12×3 = 36 ✔ (given)
- 7 → 12×7 = 84 ✔ (given)
- 8 → 12×8 = 96 ← missing
- 0 → 12×0 = 0 ✔ (given)
- 6 → 12×6 = 72 ← but 72 is listed? Wait, in the user’s text: “36, 84, 72, 0, 12, 108, 48” — that’s 7 numbers, but 8 segments.
Actually, re-reading: “Complete the multiplication wheel.” and the wheel has 8 segments. The numbers written inside are: 36, 84, 72, 0, 12, 108, 48 — that’s 7, so one is missing.
Which one is missing? Let’s map:
Assume the outer numbers are placed at positions, and inner products correspond.
Typical order might be clockwise starting from top:
Position 1: outer 3 → inner 36
Position 2: outer 7 → inner 84
Position 3: outer 8 → inner ? → should be 96
Position 4: outer 0 → inner 0
Position 5: outer 6 → inner 72
Position 6: outer 1 → inner 12
Position 7: outer 9 → inner 108
Position 8: outer 4 → inner 48
Yes! So the only missing inner number is for outer 8 → 12 × 8 = 96
So the answer for the wheel is to fill in 96 in the segment corresponding to 8.

Now, compiling all final answers clearly.
Final Answer:
Skip count by 12s:
0 → 12 → 24 → 36 → 48 → 60 → 72 → 84 → 96 → 108 → 120

12 × 8 = 96
12 × 5 = 60
2 × 12 = 24
12 × 3 = 36

Part 5: Complete the multiplication wheel
The center is “12x”, so we multiply 12 by each number around the wheel.
Numbers around the wheel: 3, 7, 8, 0, 6, 1, 9, 4 (going clockwise from top)
Wait — let’s list them as shown in the image description (from the user's upload):
Looking at the wheel: it has outer numbers: 3, 7, 8, 0, 6, 1, 9, 4 — but arranged in a circle. The inner ring should be 12 × that number.
Actually, looking at standard multiplication wheels like this, the outer numbers are the multipliers, and you write the product inside the corresponding segment.
But in the diagram described, there’s an inner ring with some numbers already filled? Wait — the user wrote:
“Complete the multiplication wheel.” and shows a wheel with center “12x” and outer numbers: 3, 7, 8, 0, 6, 1, 9, 4 — and some inner numbers given: 36, 84, 72, 0, 12, 108, 48 — wait, actually, let me reconstruct based on typical layout.
Actually, from the text: “Complete the multiplication wheel.” and the wheel has:
Outer ring (multipliers): probably 3, 7, 8, 0, 6, 1, 9, 4 — but let’s match the products given.
In the wheel, some products are already written: 36, 84, 72, 0, 12, 108, 48 — and one missing? Or maybe all except one?
Wait — the user says: “Complete the multiplication wheel.” and lists:
Center: 12x
Outer numbers (clockwise from top?): 3, 7, 8, 0, 6, 1, 9, 4
Inner products shown: 36 (for 3), 84 (for 7), ? (for 8), 0 (for 0), ? (for 6), 12 (for 1), 108 (for 9), 48 (for 4)
Wait — let’s assign:
If outer number is N, inner product is 12 × N.
So:
- 3 → 12×3 = 36 ✔ (given)
- 7 → 12×7 = 84 ✔ (given)
- 8 → 12×8 = 96 ← missing
- 0 → 12×0 = 0 ✔ (given)
- 6 → 12×6 = 72 ← but 72 is listed? Wait, in the user’s text: “36, 84, 72, 0, 12, 108, 48” — that’s 7 numbers, but 8 segments.
Actually, re-reading: “Complete the multiplication wheel.” and the wheel has 8 segments. The numbers written inside are: 36, 84, 72, 0, 12, 108, 48 — that’s 7, so one is missing.
Which one is missing? Let’s map:
Assume the outer numbers are placed at positions, and inner products correspond.
Typical order might be clockwise starting from top:
Position 1: outer 3 → inner 36
Position 2: outer 7 → inner 84
Position 3: outer 8 → inner ? → should be 96
Position 4: outer 0 → inner 0
Position 5: outer 6 → inner 72
Position 6: outer 1 → inner 12
Position 7: outer 9 → inner 108
Position 8: outer 4 → inner 48
Yes! So the only missing inner number is for outer 8 → 12 × 8 = 96
So the answer for the wheel is to fill in 96 in the segment corresponding to 8.
