Grade 1 Math Worksheet: Concepts of Multiplication - Students write addition and multiplication equations for each picture.

Let’s go through each problem one by one. We’ll count the groups and how many are in each group, then write both an addition sentence (adding the same number over and over) and a multiplication sentence (number of groups × how many in each group).

---

Problem 1:
There are 3 boxes. Each box has 8 butterflies.
Addition: 8 + 8 + 8 = 24
Multiplication: 3 × 8 = 24

---

Problem 2:
There are 2 boxes. Each box has 8 purple shapes.
Addition: 8 + 8 = 16
Multiplication: 2 × 8 = 16

---

Problem 3:
There are 3 boxes. Each box has 6 snails.
Addition: 6 + 6 + 6 = 18
Multiplication: 3 × 6 = 18

---

Problem 4:
There are 4 boxes. Each box has 4 frogs.
Addition: 4 + 4 + 4 + 4 = 16
Multiplication: 4 × 4 = 16

---

Problem 5:
There are 2 boxes. Each box has 6 flamingos.
Addition: 6 + 6 = 12
Multiplication: 2 × 6 = 12

---

Problem 6:
There are 6 boxes. Each box has 2 candy canes.
Addition: 2 + 2 + 2 + 2 + 2 + 2 = 12
Multiplication: 6 × 2 = 12

Problem 7:
There are 9 Santa faces total — arranged as 5 on top row and 4 on bottom row. But they’re not grouped equally? Wait — let’s look again.

Actually, looking closely: It’s 9 individual Santas, but maybe we’re supposed to see them as 9 groups of 1? Or perhaps it’s meant to be 3 rows of 3? No — the image shows 5 in first row, 4 in second. That’s uneven.

Wait — actually, re-examining: The problem says “write addition and multiplication sentence for each picture.” For #7, there are 9 separate Santa pictures — no grouping boxes. So if each is its own group of 1, then:

Addition: 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9
Multiplication: 9 × 1 = 9

But that seems odd. Alternatively, maybe it’s 3 groups of 3? But the layout doesn’t show that. Let me check the original image description again — ah, in the user’s image, problem 7 shows 9 Santa heads arranged in two rows: 5 on top, 4 on bottom. Since they’re not in equal groups, this might be a trick — but for Grade 1 multiplication concepts, we usually only do equal groups.

Wait — perhaps I miscounted. Let me recount from the image description: “7. [Santa images]” — actually, looking at standard worksheets like this, sometimes they arrange them in grids. If it’s 3 columns and 3 rows, that would be 9. But here it’s shown as 5 and 4 — which is 9 total, but unequal.

Hmm — perhaps it’s intended to be seen as 9 groups of 1. That’s the only way to make multiplication work here.

So:
Addition: 1+1+1+1+1+1+1+1+1 = 9
Multiplication: 9 × 1 = 9

Alternatively, maybe it’s 1 group of 9? Then:
Addition: 9
Multiplication: 1 × 9 = 9

But typically, multiplication is “groups of”, so 9 groups of 1 makes more sense for repeated addition.

I think for consistency with Grade 1 level, we’ll go with 9 groups of 1.

Problem 8:
There are 2 boxes. Each box has 5 girls.
Addition: 5 + 5 = 10
Multiplication: 2 × 5 = 10

---

Now let’s double-check all calculations:

1. 8+8+8=24 ✔️, 3×8=24 ✔️
2. 8+8=16 ✔️, 2×8=16 ✔️
3. 6+6+6=18 ✔️, 3×6=18 ✔️
4. 4+4+4+4=16 ✔️, 4×4=16 ✔️
5. 6+6=12 ✔️, 2×6=12 ✔️
6. 2 added 6 times = 12 ✔️, 6×2=12 ✔️
7. 1 added 9 times = 9 ✔️, 9×1=9 ✔️
8. 5+5=10 ✔️, 2×5=10 ✔️

All correct!

Final Answer:

1. Addition: 8 + 8 + 8 = 24; Multiplication: 3 × 8 = 24
2. Addition: 8 + 8 = 16; Multiplication: 2 × 8 = 16
3. Addition: 6 + 6 + 6 = 18; Multiplication: 3 × 6 = 18
4. Addition: 4 + 4 + 4 + 4 = 16; Multiplication: 4 × 4 = 16
5. Addition: 6 + 6 = 12; Multiplication: 2 × 6 = 12
6. Addition: 2 + 2 + 2 + 2 + 2 + 2 = 12; Multiplication: 6 × 2 = 12
7. Addition: 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9; Multiplication: 9 × 1 = 9
8. Addition: 5 + 5 = 10; Multiplication: 2 × 5 = 10
