Instructional Ideas

• Group learners in pairs to work on the interactive together, using notes and supporting one another throughout the problem-solving process
• Assign the interactive for homework, have pupils write their answer to question five on a piece of paper in preparation for a whole-class discussion the next day 
• Direct early finishers to work on the interactive for extra practice after other tasks are completed

Classroom Considerations

• A free CK-12 is required to play the interactive 
• Participants should reset the tool between questions

Pros

• Feedback is provided after each response
• If needed, hints and additional concept information is available
