Lesson Plan: Sphero Racer! Mean, Median, Mode and Range

Written By: Sarah Becker
Grade Level: 5-7

Time Allotment

3 – 45 min class periods


Conduct races with Sphero to collect data and calculate mean, median, mode and range. Students will be asked to make predictions, conduct Spero races, tabulate data, make calculations. The class will graph data and analyze race results. Students will be asked to write statistical descriptions and make analytical predictions.

  • Introductory Activities

    Day 1
    • Learn Vocabulary
    • Gain background information
    • Practice skills

    Vocabulary: Mean, Median, Mode and Range

  • This document has a link to the Dunk Tank Video and the Khan Academy Link
  • This document can be printed or used digitally for students to complete notes

  • Videos and activities can be watched as a class with a projector and screen or students can work independently or as partners depending on what equipment is available. Both video options have explanations on the terms, what they mean and how they are calculated. Each video option has interactive activity to help practice skills related the mean, median, mode
    Depending on time and your class after videos and activities
    1. more practice problems
    2. watch introduction video for Sphero and take time to play with Sphero and the app
    3. discuss and complete the prediction sheet

    Learning Activities

    Day 2
    Activity Day – Sphero Racing
    • Set up a course for each group with tape, yarn, etc
    • Provide each group with an iPad/iPhone with Sphero app, a Sphero, some sort of stop watch, data sheet
    • Activity Documents – Predictions and Data Collection Sheet: https://drive.google.com/folderview?id=0B-W5XURsiyaHfk1UR3BDQ2ZTUXE3eFpGSGVQajRpS29CMHJ5emY4M05QWEc5ajFKLUFseE0&usp=sharing
      1. Watch Sphero introduction and activity video - Link- App, Link - Course
      2. Play with Sphero
      3. Have students run course and collect data. Time(seconds)
      4. *After experiment, each student can complete calculations
