This open-ended, challenging maths problem expands rather than restricts thinking and allows young mathematicians to use more than one strategy, heightening their awareness that problems can be solved in more than one way and can have multiple solutions. For this problem, students need to consider possible dates for the swimming carnival based on the parameters set by the principal.
