# Reflector ! Rotcelfer

## Mirror Mirror

#### An activity for two, three or four pupils working together.

Well, that's three photos of three different ways of putting some blocks together. But there's a mirror behind the black strip. In the mirror you can see the reflections.

Now here are some more pictures but only the reflection is shown and you have to place blocks that will make thst reflection.

Here's another for you to try.

Now here's two that will probably need more careful thinking.

So, one of your group makes a model, maybe something like this;
Others in the group now have to make the image that woud be seen in the mirror.
You therefore make it like the one behing the mirror, as here;
Now its over to you, remember to use a variety of colours in your models and the reflections must show the correct colour positions.

### Why do this problem?

This activity is very useful for deepening children's understanding of reflection, as well as helping them to focus on visualising things.

### Possible approach

This activity is probably best approached with a group of pupils so that whilst they can see the challenge they can talk freely with you in order to understand clearly what they need to be thinking about and imagining in their heads.

### Key questions

How can you decide what goes where?
