Now this is going to be fun! You will need another person to do this with you, although you can do it by yourself - it just won't be quite so much fun. You will also need a plastic cup - nothing breakable, please! Watch the first clip so that you can get used to the patterns and rhythms, then when you feel ready, go on to part 2. This activity is brilliant for getting you to learn and remember rhythm patterns.
And when you've had some practice, here's Part 2!
Use that skill for the second part of the lesson, where you are going to watch a brilliant opening sequence from Monsters Inc. I want you to look in particular at the way you can see the rhythms as well as hear them.
