• Assign the interactive for independent practice after direct instruction and guided practice 
• Direct pupils to write their answer to question nine in preparation for a whole-class discussion 

Classroom Considerations

• Learners should know how to solve equations dealing with percent increases and decreases 
• Those working on the interactive require a free CK-12 account

Pros

• Parts of the tool are color-coded 
• The restaurant theme sparks attention 
• Word problems are written clearly 

Cons

• The tool directly assists only a small number of problems
