Guess the Code

**See the Guess the Code Lesson Plan (attached) for variations for In-Classroom, Remote/Hybrid, and At-Home Learning.

How to Play

1. Visit code.irobot.com or open the iRobot™ Coding App.
2. Review the How to Download Projects Guide (A) (attached).
3. Select the first project code: To select a code at random, draw the first Code Card (D). NOTE: Some teachers may prefer to select a code from the Code Answer Key (C).
4. Using the selected project code, download and open the first project. Wait ten (10) seconds before pressing play, giving other players the opportunity to read through the code and guess what the robot will draw/sing. NOTE: If using the virtual simulator, make sure it is open. If using the physical Root Coding Robot, close the simulator.
5. If after ten (10) seconds, no players have guessed correctly, press “Play” on your program.
6. Players should race to guess what the robot is drawing or singing. Once a player has guessed correctly, announce that they have won the round. Allow the project to finish playing.
7. Repeat steps 3-6 until all 5-character codes have been guessed.

How to Score Points

Play a new version of the game with code drawings that students have created!

1. 10 points: Player is the first to guess the correct answer BEFORE the code has started playing.
2. 5 points: Player is the first to guess the correct answer before the project has finished playing.
3. 1 point: Player is the first to guess the correct answer AFTER the project has finished playing.
4. 0 points: No players were able to guess the correct answer.

Extension

Play a new version of the game with code drawings that students have created!

1. Challenge students to create their own code drawings using the simulator on code.iRobot.com or in the iRobot™ Coding App.
2. Students should first create their code drawing.
3. Ask students to re-name their project with their first name. To rename their project, they can click in the upper-left corner where it says “New Project.”
4. Review the How to Upload Projects Guide with students (attached).
5. Ask students to upload their projects and send you their 5-character project code.
6. Use all of the students’ codes to create your own Code Answer Key and/or Code Cards (blank versions are attached).
7. Play the game again, this time using the new project codes created by your students! To prevent cheating, warn students that they cannot guess the answer when their created code is playing.
