Bar Graphs Sheet 3B - Bug Eating Contest: Students analyze a bar graph and table to determine how many bugs each salamander ate, compare results, and answer related questions.

Let’s go step by step to solve each question using the bar graph and table.

First, let’s look at what we know from the bar graph:

- Quadra (orange bar) goes to 12 → so Quadra ate 12 bugs
- Sally (light blue bar) goes to 6 → matches table: 6 bugs
- Frazer (purple bar) goes to 14 → matches table: 14 bugs
- Newton (green bar) — there is NO green bar drawn yet! But the table says Newton ate 7 bugs, so we’ll need to draw a bar for him later.
- Tyger (red bar) goes to 16 → matches table: 16 bugs
- Captain (dark blue bar) goes to 15 → so Captain ate 15 bugs

Now fill in the missing data in the table:

→ Quadra: 12
→ Captain: 15

Question 1: Fill in the missing data in the table for Quadra and Captain.
✔ Quadra = 12, Captain = 15

---

Question 2: Draw a bar to show how many bugs Newton ate.
→ Newton ate 7 bugs. So on the graph, you would draw a green bar that stops at 7 on the “Number of Bugs Eaten” axis. (Since this is text, we can’t draw it, but you’d do it on your paper.)

Question 3: Which salamander ate the most bugs?
Look at all the numbers:
Quadra: 12
Sally: 6
Frazer: 14
Newton: 7
Tyger: 16 ← highest
Captain: 15

✔ Tyger ate the most (16)

---

Question 4: How many more bugs did Quadra eat than Sally?
Quadra: 12
Sally: 6
12 - 6 = 6
✔ 6 more bugs

---

Question 5: How many more bugs did Tyger eat than Newton?
Tyger: 16
Newton: 7
16 - 7 = 9
✔ 9 more bugs

---

Question 6: Captain ate more bugs than Sally and Quadra put together. Is this true or false?
Sally + Quadra = 6 + 12 = 18
Captain = 15
Is 15 > 18? No.
✔ False

---

Question 7: Which 2 salamanders ate exactly 20 bugs altogether?
We need two numbers that add up to 20.

Check pairs:

- Sally (6) + Frazer (14) = 20 ✔
- Newton (7) + Captain (15) = 22 ✘
- Quadra (12) + Newton (7) = 19 ✘
- Sally (6) + Captain (15) = 21 ✘
- Frazer (14) + Newton (7) = 21 ✘
- Quadra (12) + Sally (6) = 18 ✘
- Tyger (16) + anyone? Too big.

Only pair that adds to 20: Sally and Frazer

✔ Sally and Frazer

---

Final Answer:
1) Quadra: 12, Captain: 15
2) Draw a green bar for Newton at 7
3) Tyger
4) 6
5) 9
6) False
7) Sally and Frazer
