Let’s solve each problem step by step. We’ll count the objects in each group, add them together, and write the sum.
---
1)
First group: 10 red dots (2 rows of 5)
Second group: 5 red dots (1 row of 5)
→ 10 + 5 =
15
2)
First group: 1 blue dot
Second group: 9 blue dots (3 rows of 3)
→ 1 + 9 =
10
3)
First group: 6 brown dots (2 rows of 3)
Second group: 8 red dots (2 rows of 4)
→ 6 + 8 =
14
4)
First group: 5 yellow smiley faces
Second group: 10 yellow smiley faces (2 rows of 5)
→ 5 + 10 =
15
5)
First group: 5 brown dots
Second group: 9 brown dots (3 rows of 3)
→ 5 + 9 =
14
6)
First group: 7 stars (top row 4, bottom row 3)
Second group: 2 stars
→ 7 + 2 =
9
7)
First group: 10 blue dots (2 rows of 5)
Second group: 8 blue dots (2 rows of 4)
→ 10 + 8 =
18
8)
First group: 6 blue dots (2 rows of 3)
Second group: 6 blue dots (2 rows of 3)
→ 6 + 6 =
12
9)
First group: 2 stars
Second group: 2 stars
→ 2 + 2 =
4
10)
First group: 5 red apples
Second group: 9 red apples (3 rows of 3)
→ 5 + 9 =
14
11)
First group: 10 red dots (2 rows of 5)
Second group: 8 red dots (2 rows of 4)
→ 10 + 8 =
18
12)
First group: 8 yellow smiley faces (2 rows of 4)
Second group: 8 yellow smiley faces (2 rows of 4)
→ 8 + 8 =
16
13)
First group: 10 blue dots (2 rows of 5)
Second group: 6 blue dots (2 rows of 3)
→ 10 + 6 =
16
14)
First group: 6 black stars (2 rows of 3)
Second group: 2 black stars
→ 6 + 2 =
8
15)
First group: 8 white circles (top row 5, bottom row 3)
Second group: 7 white circles (top row 5, bottom row 2)
→ 8 + 7 =
15
16)
First group: 6 red dots (2 rows of 3)
Second group: 7 red dots (top row 4, bottom row 3)
→ 6 + 7 =
13
