Understanding Large Numbers
Adding millions is exciting!
When we add numbers up to millions, we're working with really big numbers! The secret is to break them
down into smaller parts using place values. Remember our place value chart? Millions are just groups of
thousands!

Hundred Thousands

How to Add Large Numbers
1️⃣ Line up the numbers by place value (ones under ones, tens under tens, etc.)
2️⃣ Add from right to left, starting with the ones place
3️⃣ Carry over if the sum in any column is 10 or more
Let's Practice Together!
Example 1: Adding Two Large Numbers
Let's add 2,345,678 + 1,234,567
2,345,678
+ 1,234,567
___________
=
Example 2: Real-World Problem
A national park had 3,456,789 visitors last year and 2,987,654 visitors this year. How many visitors total?
3,456,789
+ 2,987,654
___________

Parent Tips 🌟
- Use real-world examples like population counts or sports statistics to make large numbers more relatable.
- Practice with money - create pretend budgets in the millions to help visualize the amounts.
- Break it down - have your child add the numbers without the commas first, then add the commas back in the final answer.
