Objective: The students will describe and calculate real life applications of circumference.
Each Lesson includes the following elements:
- Background information & resource links (some to share with students & some for teachers)
- Introductory questions & information to share with the students
- Step-by-step procedure for the project
- Student handouts, charts, worksheets
- Closure exercises
- Assessment questions
Time Requirement: 2, 45 minute class periods
- The Lesson uses Scratch, a beginner drag-and-drop programming language developed at MIT. It is perfect for beginners, and no prior experience is expected or required.
- For students with more advanced programming skills, there is room to expand upon the lesson provided to do more sophisticated activities with the sensors as well as data collection and analysis techniques. Students can also use Python, Java, C++ and Node.js to program the GoPiGo robot car, but this curriculum is designed to teach and incorporate Scratch.
Recommended Grades: 5-7
Main Audience: Classroom

What else will I need that does not come with this curriculum?
For purchases of 5 or more robots, please see our GoPiGo Classroom Kit.
- GoPiGo Base Kit
- Raspberry Pi (works with any version of the Raspberry Pi)
- Wi-Fi Dongle (requires our custom Wi-Fi Dongle, even for the Pi 3, because our software is not yet totally compatible with the onboard wifi)
- microSD Card (with Dexter Industries custom software – available for purchase pre-loaded with our software or else you can download and image the cards yourself) *If you are using this in a school setting and don’t want to have to deal with your IT department to get the GoPiGo robot on your school network, we have another option which is very easy called “CINCH”. Please be sure to select a kit with the “CINCH” software. Read more about CINCH here.
- Ethernet Cable (not required if using CINCH)
- Power Wall Adapter
- AA batteries (not included, we recommend rechargeable) for each robot
- Masking Tape
- A computer with wifi & an internet connection and a web browser (Chrome preferred, but use Firefox if using touch-screen laptops)
CCSS.MATH.CONTENT.7.G.B.4 – Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

The Servo Package is a device that rotates. It connects directly to the GoPiGo and enables you to control an attached sensor’s rotation with software. This package comes with the servo and mounting hardware for attaching an ultrasonic sensor or Raspberry Pi camera to the GoPiGo Raspberry Pi robot car.
