Stage 3

Two-dimensional spatial structure B
2D shapes: Dissect two-dimensional shapes and rearrange them using translations, reflections and rotations

  • Use the terms Loading , Loading  and rotate to describe transformations of Loading  Loading 

  • Dissect and rearrange one shape to make another

  • Recognise that translations, reflections or rotations change the position and orientation but not the size of shapes (Reasons about spatial orientation)

Area: Find the area of composite figures

  • Find different ways to calculate the area of a Loading  L-shape figure

Area: Calculate the area of a parallelogram using subdivision and rearrangement

  • Show how to transform a parallelogram into a Loading  to find its area

  • Record, using words, a method for finding the area of any parallelogram

Area: Determine the area of a triangle

  • Investigate the area of a Loading  by comparing it to the area of a parallelogram with the same Loading  Loading  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
