Chess Knight Jumps on the Grid

A group challenge on a 5x5 grid where the only way to move is the chess knight's L, done with two-foot jumps. Groups plan routes to collect beanbags in as few jumps as possible, blending problem solving with jump control.

How to play

1. Chalk five 5x5 grids with 2-ft squares; groups of 5. Knight move: two two-foot jumps in a straight line and one to the side, landing inside a square (3 min).
2. Challenge 1 (4 min): starting from a corner, each member must reach the square with the center cone in as few moves as possible. The group suggests, one student jumps, and the rest count.
3. Challenge 2 (5 min): collect 4 beanbags spread over the grid. In relay, each player starts where the last one finished and makes one move; the group needing the fewest moves wins.
4. Challenge 3 (6 min): land on as many squares as possible without repeating, marking each with chalk; each player makes three moves before the next takes over.
5. Between challenges, give 30 seconds to plan out loud and trace the route on the ground with a finger.

Rules

• Every move starts and ends with both feet inside a square; if you step on a line, redo it.
• Land softly with bent knees to control the landing.
• Only one jumper on the grid at a time; everyone else waits 3 ft outside.

Variations

Adaptations

• Limited mobility: the student traces the route on a cardstock grid and directs the jumper.
• Visual impairment: a partner guides by voice square by square, and the squares are enlarged to 30 in.
• Fitness level: students who tire may walk the sideways part of the move.

Learning goals

• Control takeoff and landing in linked jumps.
• Work out routes and choose the most efficient one.
• Collaborate to solve a shared problem.

Equipment for a class of 25

• chalk: 5
• beanbags: 20
• cones: 5

Teacher tip

Many students get the L wrong: practice it first with a piece on the whiteboard. If a group gets stuck, suggest starting with the corners, which have few exits.
