The not equal (≠) symbol means that the values on either side are not equivalent (not balanced).

The equal symbol (=) means that the values on either side are equivalent (balanced).

An equation (number sentence) is a mathematical statement representing two expressions that are equivalent. It consists of two expressions, one on each side of an 'equal' symbol (e.g., 5 + 3 = 8, 8 = 5 + 3 and 4 + 3 = 9 − 2). An equation can be represented using a number balance scale, with equal amounts on each side (e.g., 3 + 5 = 6 + 2).

An equation is a statement that represents the relationship between two expressions of equal value (e.g., 12 × 3 = 72 ÷2).

Recognize that equations can be used to represent the relationship between two expressions of equal value (e.g., 4 + 2 = 2 + 4 and 6 + 1= 4 + 3).

Identify equivalent values (e.g., 3 = 3, 4 + 3 = 8 − 1, 7 = 2 + 5, etc.).

Identify and use the appropriate symbol to distinguish between equal and not equal quantities. (e.g., 8 + 2 = 7 + 3 and 1 + 4 ≠ 6 + 2)

A common misunderstanding is that the equal symbol always means “the answer comes next.” The equal symbol represents a balance between expressions. The equal symbol means “is the same as” or “another name for” or “equal in value.”

The student will create equations to represent equivalent mathematical relationships.
