Students are asked to identify expressions equivalent to a given expression and justify their responses.

Students are asked to determine if pairs of expressions are equivalent and to justify their responses.

Students are asked to identify expressions equivalent to a given exponential expression and justify their responses.

Students are asked to identify expressions equivalent to a given expression and justify their responses.

In this lesson, students use small round candies and equation mats to explore the equivalency of pairs of expressions. Then they show pairs of expressions are equivalent using properties of operations. For those that are not equivalent, they provide a counterexample.

This lesson unit is intended to help you assess how well students are able to translate between words, symbols, tables, and area representations of algebraic expressions. It will help you to identify and support students who have difficulty in recognizing the order of algebraic operations, recognizing equivalent expressions and understanding the distributive laws of multiplication and division over addition (expansion of parentheses).

In this lesson, students will use the properties of operations to generate and identify equivalent algebraic expressions. Students will apply their prior knowledge of the distributive property and combining like terms to create equivalent algebraic expressions. The hands-on memory "match" game will engage students and support student understanding of algebraic thinking.

Introductory lesson on the distributive property using word problems as context for area models.

Students are asked to determine if given expressions are equivalent.

The purpose of this task is to ask students to write expressions and to consider what it means for two expressions to be equivalent.

This task asks students to find equivalent expressions by visualizing a familiar activity involving distance. The given solution shows some possible equivalent expressions, but there are many variations possible.

Students are asked to use properties of operations to match expressions that are equivalent and to write equivalent expressions for any expressions that do not have a match.

"Students first explore arithmetic sentences to decide whether they are true or false. The lesson then introduces students to sentences that are neither true nor false but are algebraic equations, also called open sentences, such as x + 3 = 7 or 2 x = 12." from Math Solutions.

In this video, you will practice using arithmetic properties with integers to determine if expressions are equivalent.

This Khan Academy presentation models solving two-step equations with one variable.
