About This Lesson
Many children will begin to solve this problem by using a guess and check strategy. Encourage
them to find a way to record the way they solve the problem to share with the class later. This
puts their strategies in the front of their minds and also gives a starting point for discussion about
strategies. Once they begin to examine strategies, they can develop more advanced strategies. In
this lesson, children plan a strategy to get three items across the river safely.
