Ah, area and perimeter, how we've missed you. We all know that to find the area of a shape you multiply its length by its width and that perimeter is found by simply adding the lengths of the sides together. However, your knowledge will be stretched a little further than this during the 11+. You'll need to know:
- how to find the area of a triangle- https://www.bing.com/videos/search?q=area+of+a+triangle+video&docid=607989703883037052&mid=F00C8BC72E89B4466AE9F00C8BC72E89B4466AE9&view=detail&FORM=VIRE- a good introductory video. https://www.bbc.co.uk/bitesize/topics/zjbg87h/articles/zsqxfcw- video plus quiz!
- how to find the area of a compound/composite shape- https://www.bing.com/videos/search?q=area+of+a+compound+sape&view=detail&mid=FBAFBC54DBCEA5DAA2EEFBAFBC54DBCEA5DAA2EE&FORM=VIRE- a great video! https://www.mathsgenie.co.uk/compound-shapes.html- good examples to play with! https://www.scootle.edu.au/ec/viewing/L383/L383/index.html#- count the squares in this one!
- find the area by counting squares (and half squares) - https://www.mathspad.co.uk/interactives/areaSquares/areaSquares.php- excellent activity for revising, make sure you include the half squares!
Phew! We'll be working with these skills during our sessions as well. Enjoy!
