LCHL - Nets, length, area and volume
2D shapes and 3D solids, including nets of solids. Using nets to analyse figures and to distinguish between surface area and volume. Problems involving perimeter, surface area and volume. Modelling real-world situations and solving a variety of problems (including multi-step problems) involving surface areas, and volumes of cylinders and rectangular solids. The circle, and develop an understanding of the relationship between its circumference, diameter and π.
I should be able to:
Foundation Level
– investigate the nets of rectangular solids and cylinders
– select and use suitable strategies to find length of the perimeter and the area of the following plane figures: disc, triangle, rectangle, square, and figures made from combinations of these
– select and use suitable strategies to estimate the area of a combination of regular and irregular shapes
– select and use suitable strategies to find the volume and surface area of rectangular solids, cylinders and spheres
– draw and interpret scaled diagrams
Ordinary Level
– investigate the nets of prisms, cylinders and cones
– solve problems involving the length of the perimeter and the area of plane figures: disc, triangle, rectangle, square, parallelogram, trapezium, sectors of discs, and figures made from combinations of these
– solve problems involving surface area and volume of the following solid figures: rectangular block, cylinder, right cone, triangular-based prism (right angle, isosceles and equilateral), sphere, hemisphere, and solids made from combinations of these
– use the trapezoidal rule to approximate area
