Instructional Ideas

• For each equation, instruct learners to write the values of each sides of the equation on top or below the sentences
• Use the task as a warm up before beginning a lesson on comparing numbers or balancing equations. Put learners into pairs and have them solve the equations and come up with a written explanation

Classroom Considerations

• Ensure class members know what makes an equation an equation (=), and everything on the left side of the equal sign should be the same as, or equal to the right side

Pros

• Task can be used in a variety of ways, such as an assessment, guided instruction, or skills practice
• Teacher guide includes commentary and an answer key

Cons

• None
