Complete the Subtraction Statement Up to 5

Find the missing number in a subtraction statement up to 5 by counting counters, crossing out objects, and checking the leftover amount.

What You'll Learn

Identify the three parts of a subtraction statement, the start number, the amount taken away, and the difference

Count leftover counters to find a missing difference, such as \( 5 - 3 = 2 \)

Count crossed out counters to find a missing subtrahend, such as \( 5 - 2 = 3 \)

Count all counters together to find a missing start number, such as \( 3 - 1 = 2 \)

Check every completed statement by re-counting the picture from the beginning

What You'll Practice

Why This Matters

Completing subtraction statements builds your number sense and prepares you for solving equations later in math. This skill helps you understand how numbers relate to each other and develops the logical thinking you'll use in everyday situations like counting change or sharing items.
