Clue 1

Multiplication facts (1-12)

We crept into the school gym and found stacks of wooden barricades arranged in perfect rows. To count them quickly, we can multiply the number of rows by the boards in each row to gather our supplies before Piggy arrives.

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 2

Place value

Inside the safehouse workshop, a locked digital safe holds the master key. The keypad requires us to analyze the place value of the digits in the override code to pop the door open.

Clue 3

Rounding

Our motion tracker screen is a bit glitchy and only displays rounded numbers for distance. If we round the signals to the nearest ten, we can figure out exactly how close the infected beast is to our hiding spot.

110 ÷ 10 = ?
72 ÷ 9 = ?
32 ÷ 8 = ?
8 ÷ 4 = ?
30 ÷ 5 = ?
21 ÷ 7 = ?
Step 2 — cross out the sentence with each answer
