Understanding Number Sentences
Number sentences are like math puzzles waiting to be solved!
Sometimes equations have missing numbers that you need to find. Whether it's addition or subtraction, the goal is the same - make both sides of the equation equal. Think of it like balancing scales where both sides need to weigh the same!
How to Solve Missing Number Problems
1️⃣ Identify the operation - Is it addition (+) or subtraction (-)?
2️⃣ Understand the relationship - What number would make both sides equal?
3️⃣ Check your answer - Plug it back in to see if it works!

Parent Tips 🌟
- Real-life applications: Use everyday situations like shopping or cooking to create simple missing number problems ("If we need 12 eggs total and we have 5, how many more do we need?").
- Reverse the problem: After solving, ask your child to create their own missing number problems for you to solve - teaching is the best way to learn!
- Visual aids help: Use physical objects like blocks or coins to represent the numbers, making the abstract concept more concrete.
