L.I. We are learning to use line symmetry to complete an image

S.C.- I understand the terms symmetry and symmetrical and can use a mirror to help me complete a symmetrical pattern

-I can use my completed symmetrical pattern to match to an identical pattern

Primary 5 received communication from Police HQ telling us about the discovery of a partial tyre track which was found close to the home of Alan Green. Unfortunately the track found was too incomplete to be able to match it to a vehicle so we were given the task of trying to complete the image.

We inspected the track and found that half the tread was missing so we were able to use our knowledge of line symmetry to complete the whole tyre track.

We used a mirror to give us an impression of what the complete pattern would look like and then used the squares on the grid to ensure our mirror image was absolutely accurate. It took us a long time and quite a few attempts to get our symmetrical patterns right , but we eventually managed to produce the completed image. This allowed us to match it against the tyre tracks on Police HQ’s database and narrow down the make of vehicle which had left it.

We were able to demonstrate our knowledge about line symmetry during our STEM open day when parents and carers came into school to find out about our topic.
