Big Ideas: Measurement conversions are ratios. Ratio reasoning can be used with known conversion factors to convert measurement units within and between measurement systems. In this lesson, students will build an understanding of measurement conversions as equivalent fractions generated from known conversion factors. Specifically, students will convert between metric and US customary measures of length. Connections will be made to previous understandings of ratio reasoning using double number lines and ratio tables. Students will also build the understanding that conversion factors represent different values for units that represent the same measure (example 1 inch = 2.54 centimeter). This lesson expands upon work in earlier grades in measurement conversions within measurement systems, and builds toward future work in unit rates and proportional reasoning. Vocabulary: measurement conversion, equivalent ratios, ratio reasoning, multiplicative, per Special Materials: inch/centimeter rulers (optional) graph paper
