Problem Analysis:
The worksheet asks how many more items need to be added to each equation to make it true. Each equation is accompanied by visual aids (e.g., apples, bees, flowers, bananas) to help children understand the concept of addition.
Step-by-Step Solution:
####
1. First Equation: \( 3 + \_ = 5 \)
-
Visual Aid: There are 3 apples shown on the left and 5 apples in total.
-
Calculation: To find out how many more apples are needed to make 5, subtract the number of apples already present from the total:
\[
5 - 3 = 2
\]
-
Answer: You need to add
2 more apples.
-
Correct Choice: The box with the number
2 should be checked.
####
2. Second Equation: \( 5 + \_ = 8 \)
-
Visual Aid: There are 5 bees shown on the left and 8 bees in total.
-
Calculation: To find out how many more bees are needed to make 8, subtract the number of bees already present from the total:
\[
8 - 5 = 3
\]
-
Answer: You need to add
3 more bees.
-
Correct Choice: The box with the number
3 should be checked.
####
3. Third Equation: \( \_ + 4 = 10 \)
-
Visual Aid: There are 4 flowers shown on the right and 10 flowers in total.
-
Calculation: To find out how many flowers are missing on the left to make 10, subtract the number of flowers already present from the total:
\[
10 - 4 = 6
\]
-
Answer: You need
6 flowers on the left.
-
Correct Choice: The box with the number
6 should be checked.
####
4. Fourth Equation: \( 4 + \_ = 13 \)
-
Visual Aid: There are 4 bananas shown on the left and 13 bananas in total.
-
Calculation: To find out how many more bananas are needed to make 13, subtract the number of bananas already present from the total:
\[
13 - 4 = 9
\]
-
Answer: You need to add
9 more bananas.
-
Correct Choice: The box with the number
9 should be checked.
Final Answers:
1. \( 3 + \_ = 5 \): Check the box with
2.
2. \( 5 + \_ = 8 \): Check the box with
3.
3. \( \_ + 4 = 10 \): Check the box with
6.
4. \( 4 + \_ = 13 \): Check the box with
9.
Boxed Final Answer:
\[
\boxed{2, 3, 6, 9}
\]
