Fast and Slow

NCERT anchor: NCERT Looking Around Class 1 — Theme: How Things Move (comparing speed)

• Compare fast and slow motion in buses, walking, animals, and toys.
• Use words like faster, slower, and speed up in everyday talk.
• Understand that the same object can move fast or slow at different times.

1. Fast motion

Level 1 (Verbal): A cheetah runs fast; a ball rolled hard moves fast.

Level 2 (Symbolic): Fast = covers more distance in the same time.

Visual: Long arrow on a diagram = fast; short arrow = slow.

2. Slow motion

Verbal: A snail crawls slowly; walking to the water tap is often slow.

Visual: Compare two videos or drawings side by side.

3. Same thing, different speeds

A bicycle can go slow (uphill) or fast (downhill) — speed can change.

Race on the school sports day

Step 1 — Runner A reaches the finish in a short time → **fast**.
Step 2 — Runner B takes longer for the same distance → **slow**.
Step 3 — Say: "A is faster than B."
Step 4 — Check: same track length, different times.
Answer: A = fast; B = slow (compared to A).

• Is a school bus usually faster than walking?
• Name one fast animal and one slow animal.
• Does a spinning top move fast or slow at first?
• Stretch: A cricket ball is bowled fast, then rolls slow. What changed?

Revision tip: Watch traffic for one minute — point out one fast and one slow vehicle.
