This video lesson introduces distributive property. Students recall the use of rectangle diagrams to represent the distributive property and work with equations involving the distributive property with both addition and subtraction.
The purpose of this video lesson is to apply the distributive property to situations where one of the quantities is represented by a variable, as in 2 (x + 3) = 2x + 2 • 3. Students use rectangle diagrams to represent these situations, reinforcing the idea that the work with expressions is an extension of the work with numbers. They see that the distributive property can arise out of writing areas of rectangles in two different ways, emphasizing equivalent expressions as two different ways of writing the same quantity.
Generate equivalent expressions using two additive properties. This video focuses on using the associative and commutative properties of addition to combine like terms, simplify expressions, and create equivalent expressions.

To begin Module 4, students are introduced to important identities that will be useful in solving equations and developing proficiency with solving problems algebraically. In Topic A, students understand the relationships of operations and use them to generate equivalent expressions (6.EE.A.3). By this time, students have had ample experience with the four operations since they have worked with them from kindergarten through Grade 5 (1.OA.B.3, 3.OA.B.5). The topic opens with the opportunity to clarify those relationships, providing students with the knowledge to build and evaluate identities that are important for solving equations. In this topic, students discover and work with the following identities: w - x + x = w, w + x - x = w, a divided by b times b = a, a times b divided by b = a (when b ≠ 0), and 3x = x + x + x. Students will also discover that if 12 divided x = 4, then 12 - x - x - x - x = 0.
In Module 4, Topic D, students become comfortable with new notations of multiplication and division and recognize their equivalence to the familiar notations of the prior grades. The expression 2 × b is exactly the same as 2 · b and both are exactly the same as 2b. Similarly, 6 ÷ 2 is exactly the same as 6/2. These new conventions are practiced to automaticity, both with and without variables. Students extend their knowledge of the greatest common factor and the distributive property from Module 2 to expand, factor and distribute expressions using new notation (6.NS.B.4). In particular, students are introduced to factoring and distributing as algebraic identities. These include: a + a = 2 · a = 2a, (a + b) + (a + b) = 2 · (a + b) = 2(a + b) = 2a + 2b, and a ÷ b = a/b.
