• Teachers must create a free account to access

Pros

• Shows the correct answer if incorrect answers are chosen
• Provides hints to how to solve the problem

Cons

• One question is inconsistent with units, using feet in the question and meters in the answer choices
• The Learn More Information does not go well with the interactive
