An even number is a number that is divisible by 2. In other words, an even number is a whole number that can be divided by 2 without leaving a remainder. Even numbers always end in 0, 2, 4, 6, or 8, since these are the only digits that are divisible by 2.

Examples of even numbers: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on.

One way to determine if a number is even is to check if it ends in 0, 2, 4, 6, or 8. If it does, then it is an even number. Another way is to divide the number by 2 and see if the remainder is 0.

Definition: An even number is a whole number that is divisible by 2 without leaving a remainder.
Characteristics: Even numbers always end in 0, 2, 4, 6, or 8.
Examples: Examples of even numbers include 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on.
Determining if a number is even: To check if a number is even, you can look at its ones digit and see if it ends in 0, 2, 4, 6, or 8. Alternatively, you can divide the number by 2 and check if the remainder is 0.

Understanding even numbers is important in mathematics, as it helps in recognizing patterns, solving problems, and working with divisibility. Practice identifying even numbers and working with them in various mathematical operations to strengthen your understanding of this concept.

Connections to the Grade 6 Focal Points (NCTM)

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
