Counting by addition is a fundamental math skill that involves adding a specific number to a starting value to find the next numbers in a sequence. This concept helps in developing a strong foundation in basic arithmetic and prepares students for more advanced math concepts.

How to Count by Addition

To count by addition, you start with a given number and then add a specific number to find the next numbers in the sequence. For example, if you start with 3 and add 2 each time, the sequence would be 3, 5, 7, 9, 11, and so on.

Study Guide
