Instructional Ideas

• Use the items as a model for assessments
• Have pupils explain the answers using graphs

Classroom Considerations

• The class may not learn all the concepts at the same time

Pros

• Includes an answer key
• Items are accessible for all skill levels
• Prompts pupils to think abstractly and to attend to precision

Cons

• The second question is more applicable to the Geometric Measurement and Dimension domain
