####
Problem 2:
-
Image: There are 3 groups, and each group has 3 green circles.
-
Repeated Addition: \( 3 + 3 + 3 \)
-
Multiplication: \( 3 \times 3 \)
1.
Calculate the repeated addition:
\[
3 + 3 + 3 = 9
\]
2.
Calculate the multiplication:
\[
3 \times 3 = 9
\]
Answer for Problem 2:
\[
\boxed{9}
\]

####
Problem 3:
-
Image: There are 2 groups, and each group has 4 blue squares.
-
Repeated Addition: \( 4 + 4 \)
-
Multiplication: \( 2 \times 4 \)
1.
Calculate the repeated addition:
\[
4 + 4 = 8
\]
2.
Calculate the multiplication:
\[
2 \times 4 = 8
\]
Answer for Problem 3:
\[
\boxed{8}
\]

####
Problem 4:
-
Image: There are 5 orange hexagons.
-
Repeated Addition: \( 1 + 1 + 1 + 1 + 1 \)
-
Multiplication: \( 5 \times 1 \)
1.
Calculate the repeated addition:
\[
1 + 1 + 1 + 1 + 1 = 5
\]
2.
Calculate the multiplication:
\[
5 \times 1 = 5
\]
Answer for Problem 4:
\[
\boxed{5}
\]
---
####
Problem 5:
-
Image: There are 4 groups, and each group has 6 yellow squares.
-
Repeated Addition: \( 6 + 6 + 6 + 6 \)
-
Multiplication: \( 4 \times 6 \)
1.
Calculate the repeated addition:
\[
6 + 6 + 6 + 6 = 24
\]
2.
Calculate the multiplication:
\[
4 \times 6 = 24
\]
Answer for Problem 5:
\[
\boxed{24}
\]
---
Final Answers:
1. \( \boxed{6} \)
2. \( \boxed{9} \)
3. \( \boxed{8} \)
4. \( \boxed{5} \)
5. \( \boxed{24} \)
These solutions demonstrate how multiplication can be understood as repeated addition. Each step involves counting the total number of objects in the image and verifying it through both repeated addition and direct multiplication.
