Exercise Solutions 1 to 3
1 Basic Table Interpretation
Exercise 1
The table shows the number of books read by students in different months. In which month were the most books read?
Books Read by Month
Month Number of Books
January 12
February 8
March 15
April 6
May 10
Definition:

Data Table: A structured format organizing information in rows and columns to display data clearly.

Table Analysis Method:
  1. Read the title: Understand what data is being presented
  2. Examine the headers: Know what each column represents
  3. Scan the data: Look at all values in the relevant column
  4. Compare values: Identify the highest/lowest as needed
Step 1: Read the table title

"Books Read by Month" - shows number of books per month

Step 2: Identify values for each month

January: 12, February: 8, March: 15, April: 6, May: 10

Step 3: Compare to find the highest value

March has the highest value at 15 books

March had the most books read with 15
Final answer:

March had the most books read with 15 books.

Applied rules:

• Scan systematically: Go through each row to find the value you need

• Compare values: Identify the highest/lowest as required

• Read accurately: Match the correct row with the correct value

2 Data Comparison Problem
Exercise 2
Using the same table, how many more books were read in March compared to April?
Definition:

Data Comparison: Finding the difference between two values shown in the table.

Books Read by Month
Month Number of Books
January 12
February 8
March 15
April 6
May 10
Step 1: Identify the values needed

March: 15 books, April: 6 books

Step 2: Subtract the smaller value from the larger

15 - 6 = 9

Step 3: State the answer

There were 9 more books read in March than in April

9 more books were read in March compared to April
Final answer:

9 more books were read in March compared to April.

Applied rules:

• Subtraction for difference: Larger value minus smaller value gives the difference

• Accurate reading: Read exact values from the table

• Units: Include units in the final answer

3 Total Calculation Problem
Exercise 3
What is the total number of books read over all five months?
Definition:

Total Calculation: Adding all individual values together to find the sum.

Books Read by Month
Month Number of Books
January 12
February 8
March 15
April 6
May 10
Step 1: List all individual values

January: 12, February: 8, March: 15, April: 6, May: 10

Step 2: Add all values together

12 + 8 + 15 + 6 + 10 = 51

Step 3: Verify calculation

(12 + 8) + (15 + 6) + 10 = 20 + 21 + 10 = 51

A total of 51 books were read over all five months
Final answer:

A total of 51 books were read over all five months.

Applied rules:

• Addition for totals: Sum all individual values to get the total

• Accuracy: Double-check calculations

• Completeness: Include all categories in the sum

4 Multi-Step Table Problem
Exercise 4
If each book has 100 pages, how many total pages were read in January and March combined?
Books Read by Month
Month Number of Books
January 12
February 8
March 15
April 6
May 10
Definition:

Multi-Step Problem: A problem requiring more than one mathematical operation to solve.

Step 1: Find how many books were read in January and March
Step 2: Add the number of books from both months
Step 3: Multiply the total number of books by pages per book
Step 4: State the final answer
Step 1: Identify books read in January and March

January: 12 books, March: 15 books

Step 2: Add books from both months

12 + 15 = 27 books total

Step 3: Calculate total pages

27 books × 100 pages per book = 2,700 pages

Step 4: State the answer

January and March combined had 2,700 pages read

2,700 pages were read in January and March combined
Final answer:

2,700 pages were read in January and March combined.

Applied rules:

• Multi-step approach: Break complex problems into simpler steps

• Order of operations: Addition first, then multiplication

• Verification: Check if the answer makes sense in context

5 Average Calculation Problem
Exercise 5
What is the average number of books read per month over the five-month period?
Definition:

Average: The sum of all values divided by the number of values.

Books Read by Month
Month Number of Books
January 12
February 8
March 15
April 6
May 10
Step 1: Find the total number of books

12 + 8 + 15 + 6 + 10 = 51 books total

Step 2: Count the number of months

5 months (January through May)

Step 3: Calculate the average

51 ÷ 5 = 10.2 books per month

Step 4: State the answer

The average is 10.2 books per month

The average is 10.2 books per month
Final answer:

The average number of books read per month is 10.2 books.

Applied rules:

• Average formula: Sum of values ÷ Number of values

• Accurate counting: Count all relevant values

• Division: Divide the total by the number of items

Questions & Answers

Question: I sometimes get confused about which row to look at. How do I know which row has the information I need?

Answer: Great question! Here's how to identify the correct row:

  • Read the question carefully: Identify what specific information you need
  • Find the matching label: Look for the row header that matches what you're looking for
  • Trace with your finger: Run your finger across the row to avoid reading other data
  • Check the column: Make sure you're reading from the right column

For example, if the question asks about March, find the row labeled "March" and then look at the number in the "Books" column.

Practice tip: Circle or highlight the row you need before reading the value!

Question: What should I do if I'm not sure my answer is right?

Answer: Always check your work using these methods:

  • Estimate: Does your answer seem reasonable?
  • Reverse operation: If you added, subtract to check. If you subtracted, add to check.
  • Read the problem again: Does your answer address what was asked?
  • Check table reading: Go back to the table to make sure you read the right value.

For example, if you found that March had 9 more books than April (15 - 6 = 9), check by adding: 6 + 9 = 15 ✓

This verification step is crucial to ensure your answer is correct!

Question: How do I solve problems that have more than one step using data tables?

Answer: Multi-step problems with data tables can be solved by breaking them into smaller parts:

  • Read the entire problem: Understand what you need to find
  • Identify steps: Figure out what needs to be done first, second, etc.
  • Solve step by step: Complete one step before moving to the next
  • Use table data: Extract the necessary information for each step
  • Check final answer: Make sure it addresses the original question

For example, if asked "How many pages were read in Jan and Mar?" (with 100 pages per book):

Step 1: Find books for Jan (12) and Mar (15)

Step 2: Add books (12 + 15 = 27)

Step 3: Multiply by pages per book (27 × 100 = 2,700 pages)

Always follow the 5-step problem-solving method for each part!
