To solve these problems, we first need to count the number of bugs caught each day by reading the tally marks. Remember that a group of 4 vertical lines with a diagonal line through them equals 5.
Step 1: Count the bugs for each day
*
Monday: Two groups of 5 = $5 + 5 = 10$
*
Tuesday: Three groups of 5 plus 3 single marks = $5 + 5 + 5 + 3 = 18$
*
Wednesday: Five groups of 5 plus 4 single marks = $5 + 5 + 5 + 5 + 5 + 4 = 29$
*
Thursday: Six groups of 5 plus 2 single marks = $5 \times 6 + 2 = 32$
*
Friday: One group of 5 plus 1 single mark = $5 + 1 = 6$
*
Saturday: Two groups of 5 plus 2 single marks = $5 + 5 + 2 = 12$
*
Sunday: Five groups of 5 plus 1 single mark = $5 \times 5 + 1 = 26$
Daily Totals:
* Mon: 10
* Tue: 18
* Wed: 29
* Thu: 32
* Fri: 6
* Sat: 12
* Sun: 26
Step 2: Solve each question
1)
How many fewer bugs were caught on Saturday than were caught on Thursday?
* Thursday: 32
* Saturday: 12
* Calculation: $32 - 12 = 20$
2)
Which day had the greatest number of bugs caught?
* Looking at our totals, 32 is the highest number.
* Answer: Thursday
3)
Which day had exactly 24 bugs caught?
* Looking at our totals (10, 18, 29, 32, 6, 12, 26), none of the days have exactly 24.
* Answer: None
4)
How many days were more than 27 bugs caught?
* We are looking for numbers strictly greater than 27.
* Wednesday (29) and Thursday (32) fit this criteria.
* Answer: 2 days
5)
How many bugs were caught on Tuesday?
* From our count in Step 1.
* Answer: 18
6)
How many more bugs were caught on Sunday than were caught on Monday?
* Sunday: 26
* Monday: 10
* Calculation: $26 - 10 = 16$
7)
How many days were fewer than 12 bugs caught?
* We are looking for numbers strictly less than 12.
* Monday (10) and Friday (6) fit this criteria.
* Answer: 2 days
8)
Which day had more bugs caught? Friday or Wednesday?
* Friday: 6
* Wednesday: 29
* 29 is greater than 6.
* Answer: Wednesday
9)
Which day had the fewest number of bugs caught?
* Looking at our totals, 6 is the lowest number.
* Answer: Friday
10)
Which day had fewer bugs caught? Friday or Monday?
* Friday: 6
* Monday: 10
* 6 is less than 10.
* Answer: Friday
Final Answer:
1. 20
2. Thursday
3. None
4. 2
5. 18
6. 16
7. 2
8. Wednesday
9. Friday
10. Friday
