Today you are exploring calculating missing angles on a straight line. You would have looked at this last year so it will hopefully be familiar to you.
I would like you to log on to Expresso, go to Maths, Measuring angles (Upper), videos. Watch the finding unknown angles video and then complete the finding unknown angles on a straight line activity.
I have attached a PowerPoint which explains this further if you are finding it tricky and also some other activities to try if you would like.
