Week 6 Maths Area and Perimeter 3D Shapes Try solving these anagrams – they are all related to Area and Perimeter • THELNG • DITHW • RIPMETREE • AEAR • RELATING Try solving these anagrams – they are all related to Area and Perimeter • THELNG = LENGTH • DITHW = WIDTH • RIPMETREE = PERIMETER • AEAR = AREA • RELATING = TRIANGLE Session Aims • Define Area and Perimeter • Calculate Area and Perimeter in a range of 2D shapes Including triangles • Understand how to find the Area and Perimeter of compound shapes • Test prior knowledge of 3D shapes by: Answering quiz questions Identifying edges, corners, and faces Drawing nets of 3D shapes • What is Perimeter? • What is Area? • What is Perimeter? It is the distance around a 2D shape • What is Area? • What is Perimeter? It is the distance around a 2D shape • What is Area? It is the amount of space inside a 2D shape Calculating Perimeter 7m 3m 3m 7m Calculating Perimeter 7m 3m 3m 7m Just add all of the sides together: 7 + 7 + 3 + 3 = 20m Calculating Area 7m 3m 3m 7m Calculating Area 7m 3m 3m 7m Multiply Length by Width: 7 x 3 = 21m² Compound Shapes • Compound shapes are really just different rectangles joined together. Just find the area of each part and then add them together.
