Absolutely! Let’s solve this step by step.

## 🎯
Task:
You are given a
tally chart showing how many of each bird were counted in a garden. You need to
draw a bar chart using that data.
---
##
✔ Step 1: Understand the Tally Chart
Each “group of 5” is shown as a diagonal line crossing 4 vertical lines: `||||` = 4, and `||||` with a diagonal = 5.
Let’s count the tallies for each bird:
🐦 Robin:
- Tally: `|||| |||| |||| ||||`
- That’s 4 groups of 5 →
4 × 5 = 20
✔ Robin = 20
---
🐦 Blue tit:
- Tally: `|||| |||| |||| |||| |||`
- 4 groups of 5 + 3 extra → (4 × 5) + 3 =
20 + 3 = 23
✔ Blue tit = 23
---
🐦 Wren:
- Tally: `|||| |||| ||`
- 2 groups of 5 + 2 extra → (2 × 5) + 2 =
10 + 2 = 12
✔ Wren = 12
---
🐦 Goldfinch:
- Tally: `|||| |||`
- 1 group of 5 + 3 extra → 5 + 3 =
8
✔ Goldfinch = 8
---
🐦 Blackbird:
- Tally: `|||| |||| |||| |||`
- 3 groups of 5 + 3 extra → (3 × 5) + 3 =
15 + 3 = 18
✔ Blackbird = 18
---
🐦 Nuthatch:
- Tally: `|||| |||| |||| |`
- 3 groups of 5 + 1 extra → (3 × 5) + 1 =
15 + 1 = 16
✔ Nuthatch = 16
---
##
✔ Step 2: Draw the Bar Chart
The grid is already set up for you:
-
Y-axis (vertical): Goes from 0 to 26 in steps of 2.
-
X-axis (horizontal): Has the bird names: Robin, Blue tit, Wren, Goldfinch, Blackbird, Nuthatch.
You need to draw a
bar for each bird, where the
height of the bar matches the number of birds counted.
---
## 📊 How to Draw Each Bar:
> 💡 Remember: The Y-axis goes up in steps of 2 (0, 2, 4, 6, ..., 26). So if a bird has 20, draw the bar up to the line labeled
20.
Here’s what to draw:
| Bird | Count | Bar Height (on Y-axis) |
|------------|-------|------------------------|
| Robin | 20 | Up to
20 |
| Blue tit | 23 | Between
22 and
24 — so halfway between those two lines |
| Wren | 12 | Up to
12 |
| Goldfinch | 8 | Up to
8 |
| Blackbird | 18 | Up to
18 |
| Nuthatch | 16 | Up to
16 |
---
## 🖍️ Drawing Tips:
- Use a ruler or draw straight lines.
- Make sure each bar is directly above its bird name.
- Color or shade each bar if you like (optional).
- Make all bars the same width.
---
## 🧠 Why This Works:
This activity teaches you how to
convert tally data into a visual bar chart, which helps you compare quantities easily. For example, you can instantly see that
Blue tit was the most common bird (23), and
Goldfinch was the least (8).
---
##
✔ Final Answer Summary:
Draw bars on the chart with these heights:
-
Robin: 20
-
Blue tit: 23
-
Wren: 12
-
Goldfinch: 8
-
Blackbird: 18
-
Nuthatch: 16
---
✔ You’ve now successfully turned tally data into a bar chart!
If you’re doing this on paper, just shade or color in the correct number of squares for each bird. If you're drawing digitally, use the grid lines to guide your bar heights.
Happy graphing! 🐦📊
