The task involves solving addition problems using the "Make a Ten" strategy. This strategy helps simplify addition by breaking numbers into parts that add up to 10, making the calculation easier. Let's solve each problem step by step.
Problem 1: \( 8 + 3 \)
#### Step 1: Break down the numbers to make a ten.
- Start with 8. To make a ten, we need 2 more (since \( 8 + 2 = 10 \)).
- Take 2 from the 3 and add it to 8 to make 10.
- The remaining part of 3 is \( 3 - 2 = 1 \).
#### Step 2: Rewrite the equation.
- \( 8 + 3 \) becomes \( 10 + 1 \).
#### Step 3: Solve the simplified equation.
- \( 10 + 1 = 11 \).
#### Final Answer:
\[ 8 + 3 \rightarrow 10 + 1 = 11 \]
Problem 2: \( 9 + 4 \)
#### Step 1: Break down the numbers to make a ten.
- Start with 9. To make a ten, we need 1 more (since \( 9 + 1 = 10 \)).
- Take 1 from the 4 and add it to 9 to make 10.
- The remaining part of 4 is \( 4 - 1 = 3 \).
#### Step 2: Rewrite the equation.
- \( 9 + 4 \) becomes \( 10 + 3 \).
#### Step 3: Solve the simplified equation.
- \( 10 + 3 = 13 \).
#### Final Answer:
\[ 9 + 4 \rightarrow 10 + 3 = 13 \]
Problem 3: \( 7 + 5 \)
#### Step 1: Break down the numbers to make a ten.
- Start with 7. To make a ten, we need 3 more (since \( 7 + 3 = 10 \)).
- Take 3 from the 5 and add it to 7 to make 10.
- The remaining part of 5 is \( 5 - 3 = 2 \).
#### Step 2: Rewrite the equation.
- \( 7 + 5 \) becomes \( 10 + 2 \).
#### Step 3: Solve the simplified equation.
- \( 10 + 2 = 12 \).
#### Final Answer:
\[ 7 + 5 \rightarrow 10 + 2 = 12 \]
Summary of Answers:
1. \( 8 + 3 \rightarrow 10 + 1 = 11 \)
2. \( 9 + 4 \rightarrow 10 + 3 = 13 \)
3. \( 7 + 5 \rightarrow 10 + 2 = 12 \)
Final Boxed Answers:
\[
\boxed{11, 13, 12}
\]
