This Combining Like Terms Introduction Lesson includes the PowerPoint Lesson, Guided Notes, and an Assignment. I have successfully used this lesson in both general education and special education classes.
The lesson uses the example of comparing apples to oranges in order to help students identify which terms are "like" terms and can be combined. This more-concrete example helps students who may struggle with this concept have a back-up, self-correcting reminder. You'll find yourself reminding students that they can't be comparing or mixing apples and oranges.
The lesson also introduces students to key vocabulary, has spot checks for students to prove their learning, and guided practice to ensure success before students complete the included assignment.
