Other Work Samples for:

Alex has demonstrated an extensive knowledge and understanding of triangles by accurately constructing and labelling three different types of triangles. Mathematical ideas have been clearly and concisely communicated using mathematical terminology, and the properties of each triangle have been classified in a table, demonstrating a depth of understanding. This work sample demonstrates characteristics of work typically produced by a student performing at grade A standard at the end of Stage 3.

Grade A

The student has an extensive knowledge and understanding of the content and can readily apply this knowledge. In addition, the student has achieved a very high level of competence in the processes and skills and can apply these skills to new situations.

Foundation Statement strands

The following strands are covered in this activity:

  • Working Mathematically
    Students ask questions and undertake investigations, selecting appropriate technological applications and problem-solving strategies. They use mathematical terminology and some conventions and they give valid reasons when comparing and selecting from possible solutions, making connections with existing knowledge and understanding.
  • Measurement and Data
    Students select and use the appropriate unit to estimate, measure and calculate length, area, volume, capacity and mass. They use 24-hour time in real-life situations and construct timelines. Students draw and interpret a variety of graphs using a scale.
  • Space and Geometry
    Students construct and classify 3D objects and 2D shapes and compare and describe their properties. They measure, construct and classify angles and make simple calculations using scale.
