NC.K.CC.6
Identify whether the number of objects, within 10, in one group is greater than, less than, or equal to the number of objects in another group, by using matching and counting strategies.

Step 1: Lesson Standards & Learning Goals
This standard calls for students to use their counting skills (NC.K.CC.4, NC.K.CC.5) to count two sets and then compare them to determine if one set is greater than, less than, or equal to the number of objects in the other group. Students should have ample opportunities to count and compare concrete objects and manipulatives.
An important goal of this standard is to develop comparison language: more/greater, less/fewer, and equal/same amount. This language supports standards in successive grades where students are asked, “How many more?” and “How many less?” Students are not expected to know and use the symbols >, <, and = until first grade.

Use matching and counting skills to count and compare two sets of objects.
Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group (up to ten objects).
Develop and use appropriate vocabulary for comparing the number of items in two sets.
Explain reasoning to show that one set has more or less than another.

Greater and greater than means more.
Less and less than means fewer.
Equals means the same amount.
Different strategies can be used to count and compare two sets of objects.
When comparing two groups of objects and the number of objects match, then the groups of objects are equal.
When comparing two groups of objects and one group has items that are left over, that group has more. The other group has fewer or less.
The relationship between two numbers can be expressed as "1 more than," "2 less than," etc.

Give students two different sets of manipulatives and ask them to discuss what they notice about each set. (Ex. What do you notice about the size of each group?)
