Cardboard Box Fort Knockdown
Two teams build a wall of cardboard boxes at their end and defend it while throwing newspaper balls to knock down the other team's wall. Students practice accurate throwing, choosing between attacking and rebuilding, and teamwork.
How to play
- Build the balls (4 min): each student crumples two newspaper sheets into a tight ball and wraps it with three turns of masking tape.
- Set up two 20 x 10 yard fields split in half, with a 2-yard fort zone at each end; teams of 6.
- Build the forts (2 min): each team stacks 10–12 boxes in its zone any way it likes, without taping or holding them.
- Play (four 3-minute rounds): throw from behind the center line; each opposing box that falls or leaves the zone is a point.
- Two builders in pinnies per team restack their own fallen boxes; everyone else throws or blocks with their body. Between rounds, count points, switch builders, and take 30 seconds to redesign.
Rules
- Throw underhand or sidearm only, never at a face.
- No crossing into the other half to grab balls.
- A box only counts if a ball knocks it down.
- Safety: never throw at a builder who is lifting a box.
Variations
Easier
Throw from a line 4 yards from the other fort, with no builders.
Standard
Throw from the center line with two builders per team.
Harder
Small boxes are worth three points and there is only one builder, who changes every minute.
Adaptations
- Limited mobility: throws seated at the center line or acts as the architect who designs the fort.
- Autism or shyness: fixed builder with a clear job, away from the busiest throwing area.
- Fitness level: weaker throwers step one stride closer; strong throwers use the other hand.
Learning goals
- Throw accurately at a target from a medium distance.
- Decide whether to attack, defend, or rebuild.
- Make game equipment from reused paper and boxes.

Teacher tip
Collect boxes from the cafeteria or local stores; shoe boxes topple better than huge ones. Well-taped balls last all year.
