Instructional Ideas

• Post the discussion question on a classroom blog, direct learners to answer using complete sentences then reply to at least one peer
• Assign the link as a May Do activity for pupils to work when they complete tasks early
• Walk through the interaction with the class, think-aloud the steps needed to take and ask for volunteers for help in solving problems 

Classroom Considerations

• Remind learners to reset the model when needed 
• Participants should be familiar with properties of operations 

Pros

• The balloons are color-coded 
• Correct answers are praised 
• Hints and information are offered  

Cons

• None
