Скачать или смотреть How to Add & Subtract Linear Expressions | 7.EE.A.1 💚

In this video lesson we will learn how to add and subtract linear expressions. We will discover the difference between linear and nonlinear expressions. We will apply what we have learned about like terms to find sums and differences of linear expressions. We will use algebra tiles to model finding sums and differences. Through the use of algebra tiles we will deepen your understanding of equivalent expressions by using visual representation of terms. We will also learn the vertical method to add and subtract expressions. Student practice is embedded in the lesson with modeled exemplar solutions.

Use properties of operations to generate equivalent expressions.
7.EE.A.1 Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
7.EE.A.2 Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related.
