Mysterious Wonder Wheel

Mysterious Wonder Wheel is a Grade 1 addition puzzle where students arrange number circles so every line of three numbers has a sum of 12. The fixed target makes the task a logic challenge: changing one number affects several lines at once, so students have to consider the entire wheel rather than solve one addition fact in isolation.

Use it for independent or partner problem solving when students are comfortable adding small numbers and are ready for a puzzle. Timing the challenge can add motivation, but the strongest discussion comes from explaining why a particular placement makes several sums work at once.
