Stop Go

Stop and Go

NCERT anchor: NCERT Looking Around Class 1 — Theme: How Things Move (starting and stopping)

What you'll learn

Things go (move) and stop (rest) when a force acts or is removed.
Connect traffic lights, whistles, and brakes to stop-and-go in real life.
Describe motion changes: start moving, keep moving, stop.

Key concepts

1. Go (start moving)

Level 1 (Verbal): Green light → cars go. Whistle at kho-kho → players run.

Level 2 (Symbolic): Go = motion begins or continues.

Visual: Green circle on traffic signal = go.

2. Stop (rest)

Verbal: Red light → stop. Referee blows whistle → freeze.

Visual: Red circle = stop; object no longer changes place.

3. Forces change motion

Push a ball → it goes. Hand catches it → it stops.

Worked example

Traffic light at the school crossing

Step 1 — Red light → cars **stop**; children wait.
Step 2 — Green light → cars **go** carefully.
Step 3 — Yellow → slow down, prepare to stop.
Step 4 — Say the rule: "Red stop, green go."
Answer: red = stop; green = go.

Common mistakes

Mistake	Why	Fix
Stop means disappear	Object is still there	Stop = no movement, object still exists
Only cars use stop/go	People and toys too	You stop running when the whistle blows
Green means run without looking	Safety first	Go means start — still look both ways
