In this lesson, students build upon their knowledge that ratios represent the relationship between two (or more) related quantities; and that, since the values in a ratio are quantities, they can be combined to form a new ratio. 393710 Adding Ratios Planning and Resources ...

### Building a Table of Ratios

Students generate equivalent ratios in a table, where values in each row of the table are a multiple of the values in the original ratio and that the entries in each column can be obtained by adding the original values in the ratio to the previous row. 393702 Building a Table ...

### Connecting Ratios and Scaling

In this lesson, students investigate how scale factors are used to make figures larger or smaller, depending on whether the ratio is greater or less than 1. 393711 Connecting Ratios and Scaling Planning and Resources Objectives Students should understand how sides of a fi...

### Ratios and Fractions

This lesson allows students to explore the differences and similarities between ratios and fractions. A ratio may be associated with a value; the value of a ratio a:b is the quotient ab (if b is not 0). 393699 Ratios and Fractions Planning and Resources Objectives Studen...
