Problem Analysis:
The task involves using a hundred chart to solve problems related to adding or subtracting 10 from given numbers. The hundred chart is a grid that lists numbers from 1 to 100 in sequential order, which helps visualize the concept of "10 more" and "10 less."
Steps to Solve Each Question:
####
a. What is 10 less than 36?
- Start at the number 36 on the hundred chart.
- To find 10 less, move up one row (since each row represents an increase of 10).
- Moving up one row from 36 brings you to
26.
Answer: 26
####
b. What is 10 more than 50?
- Start at the number 50 on the hundred chart.
- To find 10 more, move down one row (since each row represents an increase of 10).
- Moving down one row from 50 brings you to
60.
Answer: 60
####
c. What is 10 less than 677?
- Note: The hundred chart only goes up to 100, so we cannot directly use it for numbers greater than 100.
- However, the principle remains the same: subtract 10 from 677.
- \( 677 - 10 = 667 \).
Answer: 667
####
d. What is 10 more than 71?
- Start at the number 71 on the hundred chart.
- To find 10 more, move down one row.
- Moving down one row from 71 brings you to
81.
Answer: 81
####
e. What is 10 more than 63?
- Start at the number 63 on the hundred chart.
- To find 10 more, move down one row.
- Moving down one row from 63 brings you to
73.
Answer: 73
####
f. What is 10 less than 94?
- Start at the number 94 on the hundred chart.
- To find 10 less, move up one row.
- Moving up one row from 94 brings you to
84.
Answer: 84
Final Answers:
\[
\boxed{
\begin{aligned}
&\text{a. } 26 \\
&\text{b. } 60 \\
&\text{c. } 667 \\
&\text{d. } 81 \\
&\text{e. } 73 \\
&\text{f. } 84
\end{aligned}
}
\]
Explanation:
- For numbers within the hundred chart (1 to 100), moving up one row means subtracting 10, and moving down one row means adding 10.
- For numbers outside the hundred chart (like 677), the principle of adding or subtracting 10 still applies but cannot be visualized directly on the chart.
