Single-Digit Addition Basics

Single-Digit Addition

Definition

Single-digit addition refers to the process of adding two single-digit numbers together.

Basic Facts

• Single-digit numbers range from 0 to 9.
• When adding two single-digit numbers, the result is always a single-digit number or a two-digit number starting with 1.

Addition Strategies

• Counting On: Start with the first addend and count on the second addend.
• Making Ten: Use the concept of making ten to simplify addition problems (e.g., 8 + 2 = 10).

Key Concepts

• Communative Property: The order of addends does not change the result (e.g., 2 + 3 = 3 + 2).
• Associative Property: The order in which addends are added does not change the result (e.g., (2 + 3) + 4 = 2 + (3 + 4)).

Examples

• 2 + 3 = 5
• 5 + 1 = 6
• 8 + 2 = 10

Tips and Tricks

• Use visual aids like number lines or counting blocks to help understand the concept of addition.
• Practice basic facts regularly to build fluency.
