Single-Digit Addition Strategies

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.
