Which tally chart is correct?
Key Notes:
📊 What is a Tally Chart?
- A tally chart is used to count and record data.
- We use tally marks (lines) to show numbers.
- Every 5th mark crosses the first four (like a gate).
✋ How to Read Tally Marks
- | = 1
- || = 2
- ||| = 3
- |||| = 4
- = 5 (four lines + one crossing line)
- After 5, start a new group.
✅ How to Check Which Tally Chart is Correct
- Count the tally marks carefully.
- Make sure every group of 5 is correct (4 straight + 1 cross).
- Match the tally marks with the given number or picture.
- Check if no marks are missing or extra.
- Ensure tallies are grouped neatly.
❌ Common Mistakes to Avoid
- Writing 5 lines without crossing ❌
- Missing the 5th crossing line ❌
- Counting groups of 5 incorrectly ❌
- Adding extra or fewer tally marks ❌
🎯 Easy Example
If there are 7 apples:
- Correct tally → (5) + (2)
- That means one group of 5 and two more lines.
💡 Teaching Tip
- Ask students to count objects (like pencils or fruits) and make their own tally chart.
- Let them circle groups of 5 to check correctness easily.
