Shoulder Check Without Swerving: Read the Number

Riders roll down a narrow chalk lane and, as they pass a marker, look back over their shoulder to read a number a partner is holding up, without leaving the lane. This is the foundation of any safe lane change or left turn.

How to play

1. Chalk three lanes 1 m wide and 30 m long, 3 m apart (2 min).
2. Ride straight down the lane looking far ahead, at the end of the course, not at the wheel (4 min).
3. Shoulder check: passing the middle cone, turn your head over your left shoulder and call out the number on the card a partner holds up behind you, outside the lane (7 min).
4. Full maneuver: shoulder check, left-arm signal and move over to the next lane, like a lane change (8 min).
5. Log: out of five tries, numbers read correctly and lane exits; pair discussion (4 min).

Rules

• Helmet buckled at all times.
• The partner holding cards stands outside the lane, 6 feet from the edge.
• Only one rider per lane, and lane changes happen only if the next lane is clear.
• If you lose balance while looking back, look forward again and brake.

Variations

Adaptations

• Limited neck mobility: works on trunk rotation and discusses using a mirror.
• Hearing impairment: no spoken messages; everything is shown on visible cards.
• Nervous riders: first practice the shoulder check walking beside the bike.

Learning goals

• Look back while holding a straight line.
• Link the shoulder check, signal and lane change.
• Track personal progress with a simple log.

Teacher tip

If there are not enough bikes, ask the local police or city hall (many run bike safety programs with loaner bikes) or a cycling club, or let students bring their own with parent permission; with 10 bikes, work in groups of three that rotate. Students without a bike in that rotation hold up the cards or record the data.
