Owen et al talk about emphasizing key mathematical understandings in the context of STEAM provides a critical entry point for students to experience applying mathematics content and practices to solving problems in everyday life. Proportional reasoning is about recognizing multiplicative relationships--it builds on early number sense and is the cornerstone of higher-level mathematics. This investigation provided an avenue through which students could meaningfully apply their existing knowledge of multiplication to a new idea they were still learning, which was to interpret multiplication as scaling. Students were placed in groups of five to determine the giant's height. Groups brain-stormed entry points info the problem, identified potential measurement tools that could be helpful, tested various solution strategies, and checked the reasonableness of their solutions.
