How Things Move: Rolling, Sliding and Spinning — Answers
Part A: Ways things move
Read the box. Then circle the best answer.
Things can move in different ways. They can roll, slide, spin or bounce.
Round things, like balls and wheels, roll. Things with flat sides, like books and boxes, slide.
A spinning top spins around and around. A ball can bounce up and down.
Something needs a push or a pull to start moving.

Answer: round
Part C: True or false?
Write True or False.
Answer: False
A box has flat sides, so it slides. A round ball rolls better.
Answer: True
The round wheels roll, so the car moves easily.
Part D: Working scientifically: roll or slide?
Try it with a grown-up. Then check your predictions.
Make a ramp with a book and a tray. Try an empty can on its side and then standing on its flat end.
Answer: It will roll, because its curved side is round.
Answer: It will slide (or stay still if the ramp is not steep), because the flat end cannot roll.
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
Great work. Here's what to try next:
