Other Work Samples for:

Casey has shown a thorough understanding of volume, capacity and 3D space through labeled diagrams and numerical expressions. This knowledge has been demonstrated in visual form but Casey has not included a written explanation. The factors of 24 have been used to come up with other examples but these have not been drawn. Although Casey has not justified the reasoning, there is clear evidence of understanding. This work sample demonstrates characteristics of work typically produced by a student performing at grade B standard at the end of Stage 3.

Grade B

The student has a thorough knowledge and understanding of the content and a high level of competence in the processes and skills. In addition, the student is able to apply this knowledge and these skills to most 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.
