Answers, and what a wrong one tells you

A

1. 2

2. Save a copy If your child circles Print the table, ask what the photo needs before it is kept safe. Then point to the last box.

3. → ↓ ↓ ← If your child circles ↓ ↓, the robot would hit the rock. Ask which square is blocked and go around it.

B

1. crop If your child circles rotate, ask whether the park needs turning. Rotate turns the whole picture, so the bus would still be there.

C

1. rotate If your child circles crop, ask whether the picture has turned. Crop removes edges. It does not turn the picture.

2. crop If your child circles rotate, ask what happens to the sky. Rotate turns the whole picture, so the sky is still there.

3. recolour If your child circles crop, ask what is being removed. Crop cuts away parts. Here nothing is cut away, only the colours change.

4. 1 Open the photo · 2 Choose crop · 3 Drag the edges inwards · 4 Save a copy of the cropped photo

D

1. Look for: Says the photo has been changed, for example cropped, so it is not how the camera first took it. If your child agrees with Ali, point to the cut-off strip. Ask what happened to the photo before Ali saw it.

E

1. Look for: Names the close-up version and explains that cropping removes the other things, so the dog stands out more.

Words to use

Say“What did the crop cut away, and why might someone choose to do that?”
Instead of“Tell them the photo is the real thing, so there is nothing to think about.”

After the sheet

Take a family photo on a phone or tablet. Hold a piece of paper over one side of the screen, then talk about what the photo shows with that part cut away.

Tick what your child got right in StudyDen. Anything missed comes back in a later Look back box, so there's no need to redo the sheet.
