What is a Tally Chart?

  • A tally chart is used to count and record numbers.
  • We use tally marks (lines) to show counting.
  • Each tally mark = 1 item.

✋ Rules of Tally Marks

  • Draw one line for each item: |
  • After 4 lines, the 5th line crosses them: (||||)
  • This group makes counting easy and fast.

👉 Example:

  • 1 = |
  • 2 = ||
  • 3 = |||
  • 4 = ||||
  • 5 = |||| (with a cross line)

✅ How to Find the Correct Tally Chart

  • Count the total number of items.
  • Check the tally marks carefully.
  • Make sure every 5th mark is crossed.
  • The number of tally marks must match the total items.

🔍 Example

4

  • If there are 7 apples:
    • Correct tally = |||| + ||
  • If tally shows wrong grouping or wrong number → ❌ Incorrect chart

🚫 Common Mistakes

  • Forgetting the cross line at 5
  • Counting tally marks incorrectly
  • Writing too many or too few lines

🎯 Quick Tips for Students

  • Count slowly and carefully 👀
  • Group in 5s 👍
  • Double-check your answer ✔️
