Toll Bridge Puzzle

Illustrative MathematicsVaries

This task is intended to assess adding of four numbers as given in the standard while still being placed in a problem-solving context. As written this task is instructional; due to the random aspect regarding when the correct route is found, it is not appropriate for assessment. This puzzle works well as a physical re-enactment, with paper plates marking the islands and strings with papers attached for the tolls. Students will often be tempted by the single digit numbers to assume the route has to pass that way.
