Koolchee: Meet the Rolling Balls
Japanese name: クールチー（転がる球を合わせる）
Materials
- 2–3 soft, rollable balls per person
- Markers for end lines and safety zones
How to play
- The two groups stand behind opposite end lines. Mark a 2 m safety zone immediately in front of each line. The space between these zones is the central collision area.
- On an adult’s signal, begin by rolling one ball from each side along the ground. Aim your ball at a moving ball approaching from the other side.
- Stay behind your line. Never throw balls into the air or run into the middle. Check nearby feet, people and loose balls before rolling.
- Each collision between balls in the central area counts as one shared success for both groups. Collisions in the safety zones do not count. Continue with the next balls.
- When everyone has used their balls, stop. Retrieve only on the adult’s signal. Repeat for three rounds and record the combined number of successes.
Ways to adapt
Younger primary: end lines about 10 m apart, with success for central collisions. Older primary: vary rolling speeds. Preschool: roll one ball at a time beside an adult.
