## Common Core Math Grade 8 Represent Proportional Relationships

In this lesson, students will extend their understanding of proportional relationships to discover that they are one kind of linear function.

## Common Core Math Grade 7 Ratios Involving Complex Fractions

Ratios (including rates, ratios, proportions, and percents) are commonplace in everyday life and critical for further study in math and science. In Grade 7, students extend the concepts of unit rate developed in Grade 6 to applications involving complex fractions.

## Common Core Math Grade 6 Division with Fractions

In Grade 5, students divided whole numbers by unit fractions.
Students continue this understanding in Grade 6 by using visual models and equations to divide whole numbers by fractions and fractions by fractions to solve word problems.
In Grade 7, students will continue their work with fractions to include all rational number operations (positive and negative). Students

## Common Core Math Grade 5 Multiplication as Scaling

This lesson introduces multiplication as scaling. Students already know that multiplying a number by 1 results in the original number. Now they learn that multiplying a number by a whole number greater than 1 results in a product greater than the original number, and multiplying a number by a fraction less than 1 results in a product less than the original number.
