Students will use previous knowledge of Ozobots and coding to color program their Ozobot to run correctly through the maze.
- Be able to choose one of the Ozobot mazes provided.
- Be able to use the color codes provided to code each set of boxes correctly to move Ozobot through the maze.
Computer science: Computer science us using computers to solve problems and create new technology.
Persistence: Persistence is trying again, and again, and again.
Algorithm: An algorithm is a list of steps that you can follow to finish a task.
Program: A program is an algorithm that has been coded into something that can be run by a machine.
To prepare for this lesson:
You will want to get to know your Ozobot.
Watch this video tutorial on How to Use Your Ozobot.
Make sure you know how to code your Ozobot Bit or Evo and calibrate it.
Practice using the mazes and print out color code sheet below in color for students to use.
Decide how you want to split up your students. You can do individual, partner, or groups of three. (Smaller groups = more hands-on opportunities.)
Make sure you have enough markers for each group RED, BLUE, BLACK, GREEN.
Depending on grade level, you may want to add non-negotiables to the activity. For example, you must have one U-turn, two cruises, etc.
Note: Depending on grade level, you may want to pre-calibrate the Ozobots.
See the Accommodations Page and Charts on the 21things4students website in the Teacher Resources.
Directions for this activity:
The teacher will say to students, “Today, you are going to be computer programmers!”
Review vocabulary. What is Programming? What is an Algorithm?
The teacher will say to students, “Today you will be color coding Algorithms”
Have students watch Ozobot video.
Put student into groups.
Allow students to pick their maze.
Students must plan and color code first. Once they are done, they may get an Ozobot.
Students will need to calibrate Ozobot.
If time permits, you may allow students to try other people’s mazes.
Different options for assessing the students:
- Check for understanding
- Ozobot Maze rubric
MITECS Competencies & ISTE STANDARDS
MITECS: Michigan adopted the "ISTE Standards for Students" called MITECS (Michigan Integrated Technology Competencies for Students) in 2018.
5a. Students formulate problem definitions suited for technology-assisted methods such as data analysis, abstract models and algorithmic thinking in exploring and finding solutions.
5d. Students understand how automation works and use algorithmic thinking to develop a sequence of steps to create and test automated solutions.
Devices and Resources
CONTENT AREA RESOURCES
The students use boxes on maze to create a story that Ozobot runs through.
The students create a math problem. Add or subtract a number at each stop.
The students create a path for states of matter in the boxes provided.
