TRANSCRIPT
Directions:
• Have students divide up into 2 teams• Have the batter come up to the board• Arrange 3 chairs like a baseball diamond in
the room where the board is home plate. Each chair represents a base
• Let the batter pick their pitch (1st, 2nd, 3rd base or home run)
• Have a selection of questions for each type that are easy, medium, hard and difficult.
• cont
Directions:
• If the student gets the question correct they move to the appropriate base.
• If students are already on base they must be FORCED from their base, NO STEALING.
• If a student is on 2nd and a student chooses 1st base then the student on 2nd remains on 2nd. If the student at the board chooses 2nd base then if the student gets the answer correct the 2nd base student will be moved to 3rd base. If the student at the board chose 3rd base then the 2nd base student would be forced home.
• cont
Directions:
• If the student gets the question WRONG then it is a pop fly and the ball needs to be caught by the other team.
• The other team will work together to come up with an answer. A pre determined team captain will speak for the group as to what the answer is. If the other team gets it correct then everyone from the first team takes their seat and the other team is up to bat. (there should be a pre determined batting order)
• Cont…
Directions:
• Keep score. Every time a student makes it back to home plate the team gets a point.
