Year 5 apply area and perimeter to a design brief. In a Seesaw activity, each child opens a 20 by 15 squared grid in which every square stands for 1 m², and designs a small zoo with five rectangular enclosures: 12 m² for meerkats, 16 m² for tortoises, 24 m² for otters, 30 m² for goats and 36 m² for wallabies. They choose the length and width of each in whole metres, draw it along the grid lines with the pen tool, and add text labels for its area and its perimeter, which is the fencing it needs. Then they total the fencing for the whole zoo. A child who draws 3 by 4, 4 by 4, 4 by 6, 5 by 6 and 6 by 6 needs 96 m of fence, and one who draws 1 by 12, 2 by 8, 2 by 12, 3 by 10 and 3 by 12 needs 130 m for the same five areas. Children submit the plan to their journal with nothing recorded and nothing shared, and the teacher checks every area and perimeter after the lesson, as with the plans last year's class drew in their maths books.
