Understanding Number Sentences
Number sentences are like math puzzles where sometimes a piece is missing!
In complete addition and subtraction sentences, you'll often find a missing number that you need to figure out. It's like being a math detective - you use what you know to find the missing piece of the puzzle.
How to Solve Missing Number Sentences
1️⃣ Identify what's missing - Is it the first number, second number, or the total?
2️⃣ Think about the relationship - Addition and subtraction are inverse operations
3️⃣ Check your answer - Plug it back in to see if it makes the sentence true
Let's Practice Together!
Example 1: The Missing Addend

Example 2: The Mystery Subtrahend
