Multiplication as arrays What two multiplication sentences could we write for this array? 3 X 5 = 15 OR 5 X 3 = 15 We have just calculated the area of this rectangle! © www.SaveTeachersSundays.com 2013

Perimeter and area (rectangles) 5cm Think of a field with a fence around it: 3cm 3cm Perimeter … is the total length of the fence. You work it out by adding up how long all 4 sides of the fence are … 3 + 5 + 3 + 5 = 16cm 5cm Area … is how much space is inside the fence. You work it out by multiplying the length and the height of the field (rectangle) … 3 X 5 = 15cm2 The little 2 means ‘square cm’ and you always write an area as cm2 © www.SaveTeachersSundays.com 2013
