 The game we are playing today is called Geoburst. In this game, players list types of geometric objects, understand geometry concepts and begin to think about interrelationships among shapes. The materials you need to play this game include Geoburst cards, page protectors, a dry erase marker and eraser, a notepad to keep score and a timer. To set up this game, place each Geoburst card in its own page protector. Shuffle the cards, then place the cards facedown in the center of the playing surface. To begin the game, the reader from Team 1 takes a Geoburst card from the top of the stack and reads aloud the category listed at the top of the card. Team 2 tries to guess all 8 target answers that fit the category on the Geoburst card. Team 2 players guess as many answers as they can in the given time. If the card has only short answers, Team 2 has 1 minute to guess. If the card includes the word properties in the title, Team 2 has 3 minutes to guess. As Team 2 states a target answer, the reader from Team 1 marks off the answer on the card, writing on the page protector with a dry erase marker. When time is called, Team 2 gets 1 point for each correct target answer stated. In this case, the players guess 6 target answers to fit the category so they earn 6 points. Teams then switch roles and repeat play until both teams have earned at least 20 points. After play is complete, the team with the most points wins the game. After completing the game, try to think about what strategies you want to remember for the next time you play. Think about what geometry concepts you found difficult and what made them difficult. Read the properties cards again and explain how you know the properties are correct. As a variation, try to play Geoburst with more or less time. How many target answers can you guess in 30 seconds? How about 90 seconds or 5 minutes? As another variation, try to have only one team member guess the target answers. You could even have Team 1 state the target answers and Team 2 guess the category.
