Interactive Ratios and Equivalent Measurements (6th Grade)

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

Dream Box - Proportional Reasoning on a Double Number Line.  Students reason proportionally with a double number line by marking specific locations along a race course.  Lesson

Dream Box - Decimal Numbers on the Number Line.  Students locate positive and negative whole numbers on a number line by scaling the number line by powers of ten. Lesson

CCSS.MATH.CONTENT.6.RP.A.3
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.

CCSS.MATH.CONTENT.6.RP.A.3.A
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.
