Single-Digit Addition

Definition

Single-digit addition involves adding two single-digit numbers (0-9) together.

Key Concepts

Counting on: A strategy where one starts with the first number and counts on the second number to find the total.
Making ten: A strategy where one tries to make a ten by adding the two numbers, and then adding the remaining amount.

Basic Addition Facts

Counting on facts:
- 0 + 0 = 0
- 0 + 1 = 1
- 0 + 2 = 2 ...
- 1 + 0 = 1
- 1 + 1 = 2 ...
Doubles facts:
- 0 + 0 = 0
- 1 + 1 = 2
- 2 + 2 = 4 ...
Near doubles facts:
- 1 + 2 = 3
- 2 + 3 = 5
- 3 + 4 = 7 ...

Strategies for Single-Digit Addition

Counting blocks: Using physical or visual blocks to represent the numbers and counting on to find the total.
Number lines: Using a number line to visualize the numbers and count on to find the total.
Mental math: Using mental calculations to add the numbers together.

Real-World Applications

Counting objects together (e.g., toys, blocks, etc.)
Measuring quantities (e.g., measuring ingredients for a recipe)
Solving everyday problems (e.g., combining scores in a game)

Learn and practice single-digit addition strategies, including counting on, making ten, counting blocks, number lines, and mental math. Apply these concepts to real-world applications such as counting objects, measuring quantities, and solving everyday problems.
