Instructional Ideas

• Give pupils the opportunity to work in pairs, encourage them to solve for answers together 
• Send the link home for extra practice outside of the classroom
• Assign the interactive as a May Do when tasks are finished early 

Classroom Considerations

• The interactive requires a free account to CK-12
• Question five directs participants to a thread on the website. If you do not wish learners to visit the other page, direct them to write their answer on a sheet of paper 

Pros

• Hints and additional information is provided through links
• Correct answers are revealed when prompted 
• The model includes arrows for further assistance 

Cons

• The model helps create a visual but does not actually help solve the problems
