The Giant Rope-and-Chalk Compass

In pairs, one child holds the end of a rope at the center (next to a cone) while the other walks around with the rope pulled tight and a piece of chalk against the ground: out comes a perfect circle. Then they jump, walk, and dance on the circles they drew.

How to play

1. The teacher demonstrates with a child: one is the "pin" who stays still in the center, and the other is the "pencil" who walks around with the rope stretched tight (2 min).
2. In pairs, we practice without chalk: the pencil walks all the way around the pin with the rope tight (2 min).
3. Now with chalk: the pencil crouches and walks squatting or on their knees, drawing the circle; then partners switch jobs (4 min).
4. We make smaller circles by winding the rope around a hand: we get circles inside circles, like a target (3 min).
5. We play in our circles: we walk the line like tightrope walkers, jump from circle to circle, and sit in the center (4 min).

Rules

• The pin stays in the center.
• Keep the rope stretched, without yanking.
• When we switch, the pencil becomes the pin.

Variations

Adaptations

• Limited mobility: the child in the wheelchair is the center pin, or the pencil with chalk on a long stick.
• Autism: keep a steady partner, show a drawing of the finished circle first, and count each job switch.
• Visual impairment: the child is the pencil, and the rope guides their direction on its own.

Learning goals

• Explore circles and centers in space.
• Cooperate in pairs with different jobs.
• Move along a curved line while keeping balance.

Equipment for a class of 25

• Jump ropes: 12
• Cones: 12
• Sidewalk chalk: 12

Teacher tip

Use ropes about six feet long; longer ones are hard to keep tight. The typical mistake is that the pin turns and drifts, so tell them they're a tree with roots.
