## Defining, Describing and Calculating Rate

Students explore their prior knowledge of rate and extend it to create tables of values coordinating time and distance. They learn how to examine distance-time graphs and how to calculate unit rates.

5-8

Lesson Plan

## Determining Rates from Graphs

Students learn about and practice calculating rates (positive, negative and zero) using data from graphs.

Lesson Plan

## Digit in Pursuit

The CyberSquad tracks Digit’s position in time and then studies graphs to figure out what Hacker is scheming in this video from Cyberchase.

## Estimating Distance and Time

Students learn to estimate the time it takes to travel different distances based on an estimation of the time it takes to travel a part of the whole route. This reinforces basic fractional/ratio thinking, as well as early multiplication as repeated addition.

## Estimation

Students practice their estimation skills by estimating time and numbers of objects in situations in which counting is not feasible or necessary.

## Fitness Evaluated Using Rate

Students study rate and learn to fill in missing values in order to keep a constant rate.  They also learn to distinguish graphs of rate versus time and graphs of quantity versus time.

Lesson Plan

## Get Me to the Premiere on Time

Students solve simple speed and distance problems as a means to develop a generalization of the distance equation d=rt. Assessments examine whether students can solve equivalent forms of the equation for different variables.

## Intercepting Villains Using the Correct Rate

Students learn about calculating rate and practice solving the equation d=rt for different variables.

## Predicting Travel Time Using Line Graphs

In this Cyberchase video segment, Harry decides to ride his unicycle to his grandmother's house. He uses a line graph to predict the time it will take him to travel the 20 miles to her house.
