I recently had my students create board games. I gave them a list of Game Board Instructions that you can download. The students worked in groups to create a game about something they are learning about. I gave each group a different subject, and their job was to create a learning game involving concepts they're learning.
They were also responsible for comimg up with detailed instructions, creating game pieces and game cards, and decorating their game board and box.
For example, I gave one group the category vocabulary. They created a game where the players spin a spinner which tells them to either act out, draw, sculpt, or explain a vocab word. Then they pick up a vocab card that has the word and definition on it, and the students have to guess the word.
They had a great time with this activity and the kids love playing each other's games!
