The Comparing Numbers Unit involves understanding the relative position and magnitude of whole numbers, and their relationships within the numeration system. Students will answer questions such as—

• How do you know which group has more? How do you know which group has less?

• Do any groups have the same number? How do you know?

Math Concepts and Skills: 

The student compares whole numbers and understands relationships within the numeration system.

The student:

• creates a set using objects and pictures that represents a number that is more than, less than, or equal to a given number up to 20.

• generates a number that is one more than or one less than another number up to 20.

• uses comparative language to describe groups of objects up to at least 20 in each group.
