In task-based interviews 48 Kindergarten to Year 6 children were asked to choose between two jars containing different mixes of read and yellow toy bears, with the aim of giving themselves a better chance at drawing out a read bear. The children applied a variety of strategies, ranging from idiosyncratic reasons to proportional reasoning. These strategies are examined in relation to the ratio pairs presented in each jar and are compared to other strategies reported in the literature.
