Students think about how fractional measurements relate to scale models, learn about alternate ways of expressing scale ratios, and demonstrate understanding of fractions and scale in this interactive from KET. After watching video clips, students use the Notes tool in the interactive to comment on the peer’s reasoning, answer questions about scale ratios, and determine the heights of real objects based on scale ratios and models. This resource is part of the Math at the Core: Middle School Collection.
