Rounding
The arena radar scanner is old and can only show rounded numbers of players nearby. We checked the security gate logs to narrow down the suspect.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Addition
The coach counted up all the shiny neon soccer balls left on the practice field to see if any extra players had visited.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Subtraction
We took the total number of gravity boots in the locker room and subtracted the ones left behind to find out how many the thief took.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Multiplication facts (1-12)
The stadium snack bar has neat rows of space-juice boxes. We multiplied the rows by the stacks to see how many the thief drank.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
