Proportional reasoning involves thinking about parts and wholes, i.e., about fractional quantities. Yet, research on proportional reasoning and fraction learning has proceeded separately. This study assessed proportional reasoning and formal fraction knowledge in 8- to 10-year-olds. Participants (N = 52) saw combinations of cherry juice and water, in displays that highlighted either part-whole or...
