![]() Representational – Students can draw shapes or tallies to represent the terms.You can learn more about how to use Algebra tiles in our Getting Started with Algebra Tiles Guide. Concrete – Use Algebra tiles to group like terms.Use the CRA Framework – It’s no secret that we are fans of the CRA framework (you can see the many posts we have written here and here), and simplifying expressions by combining like terms is another perfect skill that fits into this method. In addition, there are lots of vocabulary terms that will be sticking around for a long time – coefficient, variable, and term – so be sure to have those words and definitions posted for easy reference. Learn about simplify using our free math solver with step-by-step solutions. Because this is so important, I recommend creating an anchor chart with some examples and non-examples of like terms. Ideally, students will have found “like” animals, giving you a perfect segway into like terms.Īnchor Chart – The basis of simplifying expressions is thoroughly understanding that a “like term” is a term with the same base (or variable) and the same exponent (or power) and that combining like terms is adding and subtracting them. After they make groups, ask them why they chose their groups. Don’t give them any additional instructions. Give each student a notecard and ask them to group themselves accordingly. Write down various animals on notecards (1 animal per notecard).The drinks are usually grouped in a drink carrier, the fries are all in one bag, and the chicken nuggets are typically in another bag. Connecting this to ordering food in the drive-thru is a real-life example that students can probably connect. You can see an example of this on one of our 7th grade student handouts below. Display a picture with different objects and ask how they would group them. ![]() Ask them – what would be an easier way to communicate his order? In this video I go over how to simplify some basic algebraic expressions involving addition, subtraction, multiplication and division.
