Often students are confused about where to start when solving a multi-step equation. In this lesson the equation is labeled as a party. The 'host' is labeled (x) with remaining operations being labeled according to their relationship to the host (friends, family, acquaintances, etc...). Technology assignments are used as one method to assess student understanding.

Students will review the definition of 'like terms' and combining like terms. They will then learn to apply this to adding polynomials. Students will have an opportunity to work practice problems as they are viewing a PowerPoint presentation of the lesson. They will be adding polynomials using both the horizontal method and the vertical method.
