The distributive property is a fundamental property in mathematics that allows us to simplify expressions and solve equations. It states that for any numbers a, b, and c, the following holds true:
a * (b + c) = a * b + a * c
This means that when we have a number outside of a set of parentheses, we can distribute that number to each term inside the parentheses by multiplying. This property is extremely useful in simplifying algebraic expressions and solving equations.
Examples:
Example 1: 3 * (2 + 4) = 3 * 2 + 3 * 4
Example 2: 5 * (x + 2) = 5x + 10
Example 3: -2 * (3x - 7) = -6x + 14
Study Guide:
Understand the concept of the distributive property: The distributive property allows us to distribute a number to each term inside a set of parentheses.
Solve equations using the distributive property: Apply the distributive property to solve equations by distributing a number to terms on both sides of the equation.
Challenge yourself with word problems: Practice solving word problems that involve the distributive property to apply the concept in real-life scenarios.
Mastering the distributive property is essential for success in algebra and higher level mathematics. By understanding and applying this property, you'll be able to simplify expressions and solve equations with confidence.

Number and Operations: Students' work in dividing fractions shows them that they can express the result of dividing two whole numbers as a fraction (viewed as parts of a whole). Students then extend their work in grade 5 with division of whole numbers to give mixed number and decimal solutions to division problems with whole numbers. They recognize that ratio tables not only derive from rows in the multiplication table but also connect with equivalent fractions. Students distinguish multiplicative comparisons from additive comparisons.
