Clue 1

Percentages

The park gate is locked. We need a secret code. The screen shows the percentage of puppies who love treats. Let us solve it.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

40% of 55 =T

50% of 40 =O

20% of 205 =H

10% of 360 =C

25% of 20 =D

50% of 38 =P

20% of 105 =V

25% of 148 =N

10% of 340 =U

10% of 70 =L

10% of 440 =G

20% of 225 =S

10% of 170 =R

75% of 52 =A

25% of 168 =K

5% of 540 =E

10% of 140 =I

Clue 2

Exponents

A collar signal is getting stronger. The power grows very fast in square steps. Work out the math to find where the signal goes.

Clue 3

Order of operations

Let us mix a special soap to wash off the muddy tracks. We must follow the math rules in the right order to get it right.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

10 × 4 - 5 =A

30 + 6 × 3 =G

10 × 3 - 11 =L

8 + 3 × 2 =T

19 + 5 × 7 =H

7 × 7 - 17 =B

3 + 4 × 6 =E

4 + 2 × 3 =I

64 + 7 × 2 =N

30 + 8 × 5 =D

8 × 12 - 24 =S

12 × 8 - 20 =P

Clue 4

Multiplication facts (1-12)

We found a pile of toy chests. There are rows of chests. Multiply the rows to find how many toys are hidden.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

Clue 5

Division facts (1-12) — the last clue

The helper dogs are hungry. We must share the bones equally among them. Divide the treats so every helper dog gets a fair share.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

2 ÷ 1 = ?

10 ÷ 1 = ?

48 ÷ 6 = ?

8 ÷ 2 = ?

35 ÷ 7 = ?

30 ÷ 10 = ?

12 ÷ 1 = ?

22 ÷ 2 = ?

6 ÷ 1 = ?

49 ÷ 7 = ?

108 ÷ 12 = ?

Step 2 — cross out the sentence with each answer

1.The villain digs a deep tunnel, then pings the sonar screen.

2.The villain crawls under the gate, then fires the snack cannon.

3.The villain crawls under the gate, then flies away with glider wings.

4.The villain dashes like a rocket, then pings the sonar screen.

5.The villain digs a deep tunnel, then fires the snack cannon.

6.The villain digs a deep tunnel, then blocks the path with bubbles.

7.The villain dashes like a rocket, then blocks the path with bubbles.

8.The villain crawls under the gate, then blocks the path with bubbles.

9.The villain lets out a booming bark, then fires the snack cannon.

10.The villain dashes like a rocket, then fires the snack cannon.

11.The villain lets out a booming bark, then pings the sonar screen.

12.The villain lets out a booming bark, then flies away with glider wings.
