Let's solve the problem step by step using the
tally chart provided in the image.
Step 1: Understand Tally Marks
Tally marks are grouped in sets of
5:
- Four vertical lines are drawn, and the fifth line is a diagonal line across the previous four.
- Each group of 5 represents 5 counts.
---
Now let’s look at each pet and count the tally marks:
---
a) How many children have a pet dog?
Dog: `|||| ||`
This is:
- One group of 5 (`||||` with a diagonal) → 5
- Plus 2 more lines → 2
Total =
5 + 2 = 7
✔ Answer: 7
---
b) How many children have a pet goldfish?
Goldfish: `|||||` (one full group of 5)
→ 5
✔ Answer: 5
---
c) How many children have a pet cat?
Cat: `|||`
→ 3
✔ Answer: 3
---
d) How many children have a pet rabbit?
Rabbit: `|`
→ 1
✔ Answer: 1
---
e) Which was the most popular pet?
Compare the numbers:
- Dog: 7
- Goldfish: 5
- Cat: 3
- Rabbit: 1
- Mouse: 2 (see below)
Wait — we haven’t counted the mouse yet.
Mouse: `||` → 2
So:
- Dog: 7
- Goldfish: 5
- Cat: 3
- Mouse: 2
- Rabbit: 1
The highest number is
7, which is for
dog.
✔ Answer: Dog
---
f) How many more children had a goldfish than a rabbit?
Goldfish: 5
Rabbit: 1
Difference: 5 - 1 =
4
✔ Answer: 4
---
g) How many more children had a cat than a mouse?
Cat: 3
Mouse: 2
Difference: 3 - 2 =
1
✔ Answer: 1
---
h) Which was the least popular pet?
We already have:
- Rabbit: 1 → lowest number
✔ Answer: Rabbit
---
✔ Final Answers:
a)
7
b)
5
c)
3
d)
1
e)
Dog
f)
4
g)
1
h)
Rabbit
