Single-Digit Subtraction

Master the simple but important rules for subtracting zero from a number, subtracting a number from itself, and subtracting one ('one less').

Learn how to use a number line as a visual tool for solving subtraction problems by starting at the first number and jumping backward.

Learn and practice the 'counting back' strategy. This involves starting with the larger number and counting backward to find the difference. It's especially useful for subtracting small numbers like 1, 2, or 3.

Practice subtracting different numbers from 10. Knowing the 'partners of 10' is a critical skill that helps with mental math and solving more complex problems later on.

Discover the powerful connection between addition and subtraction through fact families. Understanding this relationship can make solving subtraction problems much easier.

Learn the absolute basics of subtraction, including what it means to 'take away', the symbols used, and key vocabulary like 'difference'.

Apply your subtraction skills to solve real-world story problems. Learn to identify keywords that signal subtraction is needed.

Learn to find the difference by 'counting up' from the smaller number to the larger number. This is an excellent strategy when the two numbers in a problem are close together.
