# K.CC.C.7

Compare two numbers between 1 and 10 presented as written numerals.

•

## Summary:

Kindergarteners often have a natural interest in comparing quantities. This standard incorporates that into what they have learned about numbers (and how to write them). However, early learners need a firm foundation of how to represent quantities between 1 and 10 and that quantities grow bigger as they move forward in the sequence of numbers.

## Understanding the Standard:

• Students need a background of experience in representing the value of a numeral with objects or drawings. Once this is established, then it makes it easier to compare 7 and 9 and know that a set of nine objects has more than a set with seven objects.
• Students who are confused when asked to compare 7 and 9 could be asked to count out 7 blue bears, then count out 9 green bears, and asked whether 7 is more than 9, less than 9, or the same as 9.

## Questions to Focus Instruction:

• Can students identify the numbers 1 to 10 on a number line and recognize that the value of numerals increases as they move to the right?
• Can students determine which of two one-digit numbers is larger and communicate their strategy for doing so?
• Can students use the correct terminology, "greater than", "less than", or "equal to", when comparing two sets or comparing the written form of two numbers?

## Skills

Prior to: Students should be able to directly compare quantities and count out or draw a given number of objects. Go to 1.NBT.B.3 to see previous skills in this progression.
