Remove a large sheet of posterboard from the tablet. Most classrooms use oversized poster board for activities when they are not directly in front of the whiteboard. Gather the markers you will use to create the game with the class and lay the materials on a table.
Ask the students for ideas on what type of game to make. Take a consensus of what the majority of the class would like and ask them how they would create the game. Start drawing the board directly on the posterboard, scaling it to size. Create the pieces for the game as well and color them with the class asking for their opinions on each step.
Split the students into two groups and ask them to discuss game options. Instruct them to write down three ideas for oversized games and vote to choose one. Explain to the students that they will have to create the board as well as the game pieces. Additionally have each group swap and play the other group's game.
Provide students 30 minutes to create the game board and game pieces while assisting them through the process. In the end, you will have three oversized games for the classroom, so be meticulous and have them create the board with colored markers and use colored construction paper for the game pieces. Have them create a truly original game or a custom version of one they love to play.
Instruct students to create their own rules for the game. This way when the games are played in the future, they will be able to consult the rules to play it properly. Have students create simple rules so that everyone can play.
Allow each group to present their game in class by explaining the game rules and displaying the game board and game pieces. After the presentations, have the students play all three games created in class. Rotate the games through all three groups over the next few weeks so that everyone gets to play all of the games.
