This worksheet is designed to help students understand place value up to 25 using balloons as a visual aid. Each green box represents a group of 10 balloons, and the red balloons outside the boxes represent individual ones. Let's solve each problem step by step.
Problem 1:
-
Image: One green box (10 balloons) and 1 red balloon.
-
Place Value:
- Tens: 1 (from the green box)
- Ones: 1 (from the red balloon)
-
Total: \( 10 + 1 = 11 \)
Answer:
\[
\begin{array}{c|c|c}
\text{tens} & \text{ones} & = \\
\hline
1 & 1 & 11 \\
\end{array}
\]
Problem 2:
-
Image: One green box (10 balloons) and 4 red balloons.
-
Place Value:
- Tens: 1 (from the green box)
- Ones: 4 (from the red balloons)
-
Total: \( 10 + 4 = 14 \)
Answer:
\[
\begin{array}{c|c|c}
\text{tens} & \text{ones} & = \\
\hline
1 & 4 & 14 \\
\end{array}
\]
Problem 3:
-
Image: Two green boxes (20 balloons) and 1 red balloon.
-
Place Value:
- Tens: 2 (from the two green boxes)
- Ones: 1 (from the red balloon)
-
Total: \( 20 + 1 = 21 \)
Answer:
\[
\begin{array}{c|c|c}
\text{tens} & \text{ones} & = \\
\hline
2 & 1 & 21 \\
\end{array}
\]
Problem 4:
-
Image: One green box (10 balloons) and 5 red balloons.
-
Place Value:
- Tens: 1 (from the green box)
- Ones: 5 (from the red balloons)
-
Total: \( 10 + 5 = 15 \)
Answer:
\[
\begin{array}{c|c|c}
\text{tens} & \text{ones} & = \\
\hline
1 & 5 & 15 \\
\end{array}
\]
Problem 5:
-
Image: Two green boxes (20 balloons) and 3 red balloons.
-
Place Value:
- Tens: 2 (from the two green boxes)
- Ones: 3 (from the red balloons)
-
Total: \( 20 + 3 = 23 \)
Answer:
\[
\begin{array}{c|c|c}
\text{tens} & \text{ones} & = \\
\hline
2 & 3 & 23 \\
\end{array}
\]
Final Answers:
\[
\boxed{
\begin{array}{c|c|c}
\text{Problem} & \text{tens} & \text{ones} & = \\
\hline
1 & 1 & 1 & 11 \\
2 & 1 & 4 & 14 \\
3 & 2 & 1 & 21 \\
4 & 1 & 5 & 15 \\
5 & 2 & 3 & 23 \\
\end{array}
}
