Instructional Ideas

• Change up the diagrams to force pupils to calculate the measurement of the actual vase by using different scales

Classroom Considerations

• Requires access to metric rulers
• Allow for all the work to be done with the scale since both images are of the same scale

Pros

• The resource includes information on the performance of the task in a national assessment
• Provides typical understandings and misconceptions associated with individual scores

Cons

• The rubric contains dimensions in the points column
