Students compare the distributive property to sending invitations at a birthday party.
Children need to move from the manipulative expressions of the distributive property into the mathematical equations eventually. This lesson is the first step in leading them to that goal.
The children have been practicing decomposing areas and now digits in order to understand and use the distributive property.
Students will use area models and expressions to help build a solid foundation of how the distributive property works.
Practicing math problems is a great way to study for a math test!
Students are taught to look for patterns in solving mathematical problems. Starting in the lower grades, they learn that math problems can be decomposed and recomposed without its value changing (the distributive property). In these videos, you'll see teachers demonstrating how ratios, percentages, and fractions can have very similar meanings but depending on the context, they might choose one strategy over another. Students can use this knowledge to simplify and solve more difficult mathematical problems in higher grades.
Overview of the four basic number properties with examples.
The distributive property of multiplication over addition allows us to eliminate the grouping symbol, usually in the form of parenthesis. Illustrates the basic pattern or formula and how to apply it.
A Distribution Collusion: Obtaining the secrets to successfully using the distributive property.
Model with algebra tiles to generate equivalent expressions. This video focuses on visualizing the distributive property.
Sal finds equivalent expressions by combining like terms and using the distributive property. [1:57]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom.

This animated Math Shorts video explains how the distributive property can help students model and create equivalent expressions. In the accompanying classroom activity, students play a quick game where they identify common factors within an expression and work on a series of problems that expand their understanding of how to apply the distributive property. While the problems begin with whole number expressions, students soon work toward algebraic notation and eventually develop the idea that ax + bx can be rewritten as x(a + b).
Sal shows how to factor the expression 4x+18 into the expression 2(2x+9). [3:28]

Students watch a video that reveals a peer's thinking about multiplying mixed numbers and then demonstrate their understanding of the distributive property of multiplication in this interactive from KET. Students use the Notes tool to critique their peer's mathematical reasoning and then take quizzes and solve problems that require them to apply the distributive property to multiplying mixed numbers.
Students become proficient at manipulating and solving single-variable linear equations and inequalities, and using them to model and interpret contextual situations.
This page includes long multiplication worksheets for students who have mastered the basic multiplication facts and are learning to multiply 2-, 3-, 4- and more digit numbers. Worksheets can be downloaded and printed for free.
In this video [6:08], learn to use the distributive property to break up 4 x 7 into smaller numbers.
