*K.6 The student will model adding and subtracting whole numbers, using up to 10 concrete objects**.***UNDERSTANDING THE STANDARD**

**Whole numbers are 0, 1, 2, 3, 4, 5, 6, and so on.**

Addition is the process of combining or joining sets.

Subtraction can be viewed as a taking away or separating process or as comparing to find the difference between two sets.

Counting on from the larger set to determine the sum of the combined sets is a strategy for finding a sum.

Counting backward from the larger set to determine the difference between two sets is a strategy for subtraction.

Number relationships, including the following, help students develop strategies for adding and subtracting.

Instant recognition of the amount in a set of objects that are arranged in a familiar pattern such as the dots on number cubes.

One more than, one less than, two more than, two less than.
