## Design a Path

Students will use the TI-Innovator™ Rover and the provided file to design and measure a segmented path. They will then verify their measurements and directions using Rover with the provided file.

**Material List: **

- Meter sticks
- Protractors
- Rulers
- Butcher paper
- Tape (painters tape is recommended)

**Math Topic: **Geometry — Angle Measurements

## Rover Rate

Students will use the TI-Innovator™ Rover and the provided files to explore the relationship between distance, rate and time. The students will relate their findings to the actions of Rover and understand they have the ability to apply this relationship to control how it drives a given path.

**Material List: **

- Meter stick
- Stopwatch (One per student group)
- 1.5 by 2.5 meters of floor or table space
- Tape (painters tape is recommended)

**Math Topic: **Middle Grades — Distance, Rate and Time

## Two Rovers Leave the Station ...

Students will use the TI-Innovator™ Rover and the provided file to help illustrate an intersection point of two lines. Students will crash two Rovers into each other. The crash will use the horizontal distance from the origin as the dependent variable and time as the independent variable. The velocity is the slope of the linear equation, and the starting distance from the origin is the y-intercept.
