Mini-Mystery – Who Won the Race?
A fun, logic-based activity where students read clues to solve a mystery.
This teaching resource can be used as an engaging math warm-up activity, a fast-finisher activity, or even a fun indoor recess activity. Students must use logical reasoning and their knowledge of fractions, decimals, and measurement conversions to help determine the winner of a race.
Students read the statements made by the characters and combine these with the ‘Cold Hard Facts’ at the bottom of the page to decide who won the race.
An answer key has been included in the download.
