What will you learn in this lesson?

In this lesson we use the make-a-table strategy to solve problems, organizing information in rows and columns so the pattern or answer shows clearly instead of searching for it in a long text.

  • Identifies the given information and what is asked in the problem (Understand)
  • Plans to solve the problem by making a suitable table (Plan)
  • Completes the table and reads the answer from it (Solve)
  • Checks the solution and whether it is reasonable (Check)

💡 Tip: Make the heading of each column a quantity that changes in the problem, such as days and money saved, then fill in the rows until you reach what is asked.

Worked examples from the Problem-Solving Strategy: Make a Table lesson questions

Sami saves 4 riyals every day. Using a table, how many riyals will he have saved after 6 days?
  • 24
  • 20
  • 28
  • 10
✓ 24
In the table: 4, 8, 12, 16, 20, 24, so after 6 days he will have saved 24 riyals.
Each student needs two notebooks. How many notebooks are needed for 9 students?
  • 18
  • 11
  • 16
  • 20
✓ 18
In the table we add 2 for each student: 2, 4, 6, ..., 18, or 9 × 2 = 18 notebooks.

What is the first thing we do when using the "Make a table" strategy?
  • Decide what each column of the table shows and write its heading
  • Write the final answer
  • Round the numbers to the nearest thousand
  • Draw a bar graph
✓ Decide what each column of the table shows and write its heading
First we decide what information goes in each column (such as days and amount), then we complete the table.
Dana reads 15 pages every day. After how many days will she have read 90 pages?
  • 6
  • 5
  • 7
  • 9
✓ 6
In the table: 15, 30, 45, 60, 75, 90, so she needs 6 days.
Each box has 6 pens. How many boxes are needed for 42 pens?
  • 7
  • 6
  • 8
  • 36
✓ 7
In the table: 6, 12, 18, 24, 30, 36, 42, that is, 7 boxes.

FAQ about the Problem-Solving Strategy: Make a Table lesson

When do I use the make-a-table strategy?

When two quantities change together regularly, like saving 5 riyals every day; the table shows how many days it takes for the amount to reach 40 riyals (8 days).

How does a table help me discover a pattern?

When values are arranged in consecutive rows, the constant increase or decrease from one row to the next becomes visible, so we can continue the pattern easily.
