Product Description
This product is designed to support Common Core Standard 3.OA.9 for third grade. The focus is on number patterns in real world situations. This standard calls for students to examine arithmetic patterns involving both addition and multiplication. Arithmetic patterns are patterns that change by the same rate, such as adding the same number. For example, the series 2, 4, 6, 8, 10 is an arithmetic pattern that increases by 2 between each term.

This standard also includes identifying patterns related to the properties of operations.

Examples:
Even numbers are always divisible by 2. Even numbers can always be decomposed into 2 equal addends (14 = 7 + 7).
Multiples of even numbers (2, 4, 6, and 8) are always even numbers. On a multiplication chart, the products in each row and column increase by the same amount (skip counting). On an addition chart, the sums in each row and column increase by the same amount.

There are 20 task cards included in this download. These card can be printed on card stock and laminated. One option for use is to have cards placed in a math station for independent work. Another way I have used these cards is in “Buddy” work and small group. These also work well for early finishers. These cards can also be projected on the board as a math warm-up before the lesson.
