Question

draw the tally to complete the table.

what students eat at school

food choice | tally | pictogram
packed lunch | hh i | (one full circle, one half circle)
school dinner | | (two full circles, one three-quarter circle)

key: one full circle = 4 students

Explanation:

⚡ Using what you learned: Organizing Data in Tables

Step 1: Interpret the Pictogram Key

The key shows that one full circle represents 4 students:

$$ \text{Full circle} = 4 \text{ students} $$

Therefore, fractions of a circle represent proportional parts of 4:

• A half circle represents:

$$ \frac{1}{2} \times 4 = 2 \text{ students} $$

• A three-quarter circle represents:

$$ \frac{3}{4} \times 4 = 3 \text{ students} $$

Step 2: Calculate the Number of Students for School Dinner

Looking at the "School dinner" row in the pictogram column, we have:

• 2 full circles
• 1 three-quarter circle

Calculate the total number of students:

$$ 4 + 4 + 3 = 11 \text{ students} $$

Step 3: Represent the Number as a Tally

To represent the number 11 using tally marks:

• Group tallies in sets of 5 (four vertical lines with one diagonal line crossing through them).
• For 11, we need two groups of 5, plus 1 individual vertical line:

$$ \text{11} = \cancel{||||} \ \cancel{||||} \ | $$

Answer:

To complete the table for School dinner, draw 11 tally marks in the red box:

$$\cancel{||||} \ \cancel{||||} \ |$$
