VO: The Ugly Sisters are giving their mouths a lot of exercise this morning in Panto House. They’re munching on piles of cakes, but it’s making them fat and spotty. They love eating cake whilst watching the telly, but Buttons keeps getting in their way.
Angular: Oh Buttons what are you doing you silly monkey. Go on.
VO: Buttons doesn’t think this exercise routine is working. He’s the only one getting exercise, cleaning up all their mess.
Graphica: …oh you big gallute.
VO: Button's is tidying up all the toys they’ve stolen from young children at last year's Panto show. Ooh a TV remote. I wonder if it works. Hmm. I don’t think it’s working the telly. Now Button's has a way of getting his own back. Time to get some exercise. Off they go.
VO: Button's makes them turn right out of the door and travel along the road.
He wants them to go a bit faster. Ahh, fast forward should do it. He makes them walk for thirty metres. Then Button's presses right. He makes them go along for forty five metres. Then he presses right again. They go down this road for eighty metres. Then he makes them go right again. They’re definitely getting exercise now.
VO: Oh no, Button's has lost them! They’ve gone down this road for 20 metres. He needs three more instructions to get them home. Can you help him?
Look at the map. This is the route the Ugly Sisters have walked. What are the three instructions that will get the Ugly Sisters back home?
Calculate the perimeter and the area of the rectangle the Ugly Sisters will have walked.
Devise a route to and from your front door that covers exactly one kilometer.
Video summary
In the Panto House the Ugly Sisters are watching too much television and eating cakes.
Buttons finds what he thinks is a TV remote control as he is tidying up.
When he presses the buttons he finds it controls the Ugly Sisters.
Buttons makes them go round the block. They are made to walk fast until Buttons has lost them.
How can he direct them back home? Two questions of increasing difficulty show an overview map of the rectangular route round the block and the distances travelled as well as a related area and perimeter question.
This is from the series: Let's Do Maths.
Teacher Notes
This clip could be used as a lesson starter and as an introduction to measuring distance round a given shape with missing information.
Calculating perimeter of simple rectangles can be extended to more complex shapes and calculating area of compound shapes.
This clip will be relevant for teaching Maths at KS2 in England and Wales, Early and First Level and Second Level in Scotland and KS1 and KS2 in Northern Ireland.
