Dream Box – Ratios and Equivalent Measurements. Students use a ratio table to represent equivalent measurement ratios in the context of a recipe. This DreamBox lesson helps students mentally multiply and divide as they use scale factors and number relationships to understand equivalent ratios. Lesson
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
