Instructional Ideas

• Ask learners to solve these equations in pairs; take turns completing a step to solve the equation
• Use the even problems in the problem set as classwork, and assign the odd problems as homework

Classroom Considerations

• Viewing the video requires Internet access

Pros

• Reviews the distributive property within expressions before applying it to solve equations
• Includes a set of practice problems and an answer key

Cons

• Includes word problems in the practice problems, but the video does not show any examples
