Step-by-step reading method:
  1. Find the category "blue" in the tally chart
  2. Count the tally marks in the blue row
  3. Look for complete groups of 5 (4 vertical + 1 diagonal)
  4. Count any remaining individual marks
  5. Add groups (multiplied by 5) and individual marks together

Step 1: Locate the blue row

Find the row labeled "Blue" in the tally chart.

Step 2: Count the marks

Blue has: 4 vertical lines + 1 diagonal line + 1 vertical line = 6 marks

Step 3: Verify the count

One complete group (5) + 1 individual = 6 total

6 students like blue
Final answer:

6 students like blue.

Applied rules:

• Category identification: Find the correct row in the chart

• Individual counting: Each line represents one unit

• Group recognition: The diagonal line completes a group of 5

• Tally-Graph connection: Tally charts provide data for graph creation

Related Examples:
  • Red: ||||| = 5 students
  • Green: |||| = 4 students
  • Yellow: ||||| || = 7 students
Quick Tips:
  • Count each mark individually to avoid mistakes
  • Look for the diagonal line that groups 5 marks
  • Remember: 5 marks = one complete group
Frequently Asked Questions:

Q: Why is the 5th mark diagonal?
A: The diagonal line makes it easy to see groups of 5 at a glance.

Q: How do I count large numbers of tally marks?
A: Count the groups of 5, then add any extra marks.

5 Tally Comparison
Exercise 5
Which category has more: ||||| || (Toys) or ||||| |||| (Games)?
Definition:

Tally comparison: Reading the value of two different categories in a tally chart and determining which represents a larger number by counting groups and individual marks.

Note: This skill tests your ability to interpret and compare tally mark values.

  3. Compare the two values numerically
  4. State which category has more
Toys Category
Toys
7
Games Category
Games
9
Comparison
9 > 7
Step 1: Count Toys value

Toys: 1 group (5) + 2 individual = 7

Step 2: Count Games value

Games: 1 group (5) + 4 individual = 9

Step 3: Compare values

Since 9 > 7, Games has more than Toys.

Games > Toys (9 > 7)
Final answer:

Games has more with 9 compared to Toys with 7.

Applied rules:

• Individual evaluation: Calculate each category separately

• Numerical comparison: Use >, <, or = to compare values

• Accurate counting: Count groups and individual marks carefully

• Tally-Graph connection: Comparisons in tally charts translate to graph comparisons

Related Examples:
  • ||||| vs ||||| || (5 vs 7): 7 > 5
  • ||||| ||||| |||| vs ||||| ||||| || (14 vs 12): 14 > 12
  • ||||| ||||| vs ||||| ||||| (10 vs 10): 10 = 10
Quick Tips:
  • Calculate the exact value of each category before comparing
  • Count groups of 5 first, then add individual marks
  • Use the greater than (>) or less than (<) symbols to show comparison
Frequently Asked Questions:

Q: What if two categories look the same?
A: Count each category carefully to verify if they're truly equal.

Q: Can I just look at the length?
A: It's better to count exactly to be sure of the comparison.
