This is one of my favourite class activities so am very sad not to be doing this with you all. However I did think you may be able to try it at home either by yourself or get all the family involved.
The PowerPoint will automatically play the slides at a 2 second interval and show you a pair of either parallel or perpendicular lines (music should also play over the top).
You need to copy the pairs of lines with your arms and (optional) dance at the same time while shouting out whether they are parallel or perpendicular!
Play it as many time as you like until you are perfect at it.
I would love to see a video of you and your family doing this too!
Perhaps if you ever zoom your friends in the class you could try it in a group and get a taste of what it would be like in the classroom with all of us!
