## Rectangular prisms - Ashley : Grade Commentary

### Other Work Samples for:

Ashley has successfully constructed 4 rectangular prisms with a volume of 24 cubic units. The findings have been accurately recorded using a drawing showing 3-D perspective. There is an understanding of the relationship between length, breadth and height. Ashley has explained how new models were constructed by rearranging blocks and has attempted to explain the relationship of the factors of 24 using some mathematical terminology. Some of these were omitted but the student was aware of this omission. This work sample demonstrates characteristics of work typically produced by a student performing at grade C standard at the end of Stage 3.

The student has a sound knowledge and understanding of the main areas of content and has achieved an adequate level of competence in the processes and skills.

## 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.
