Content
Two-dimensional spatial structure A
Area: Calculate the areas of rectangles using familiar metric units
Area: Find the area of composite figures
Area: Calculate the areas of rectangles using familiar metric units
- Recognise the importance of using the same units of length on the sides of rectangles to create ‘square units’
- Establish the relationship between the lengths, widths and areas of rectangles
- Record, using words, the method for finding the area of any rectangle
- Calculate areas of rectangles in square centimetres (cm2), square metres (m2) and square kilometres (km2)
- Recognise that rectangles with the same area may have different dimensions
- Investigate and compare the areas of rectangles that have the same perimeter
Area: Find the area of composite figures
- Find different ways to calculate the area of a composite L-shape figure
- Show how to transform a parallelogram into a rectangle to find its area
- Record, using words, a method for finding the area of any parallelogram
- Investigate the area of a triangle by comparing it to the area of a parallelogram with the same base length and height
- Establish the relationship between the area of a triangle and the area of a parallelogram formed by duplicating and rotating the triangle
- Record, using words, a method for finding the area of any triangle
