Learn to read, write, and understand numbers up to billions.

Agenda

• Understand place value up to billions.

• Read large numbers clearly.

• Write numbers in words and digits.

• Group numbers for easier understanding.

Numbers Everywhere!

Numbers help us understand our world, from how many people live in a city to the cost of a new video game. We use huge numbers to measure distances like Earth to the Moon or the national debt. Learning about these big numbers helps us make sense of important information every day.

Comparing sizes: from small figures to planets, understanding scale.

Our Number Journey

• Understand place value up to billions (e.g., 3,456,789,012).

• Read numbers clearly, even huge ones like 9,876,543,210.

• Write numbers in words and digits (e.g., 'one billion').

• Group numbers to make them easier to understand.

Place Value Basics

Place value tells us how much a digit is worth based on its position in a number. For example, in the number 345, the '3' means 3 hundreds, not just three. Understanding this helps us read and write large numbers correctly.

Periods in Numbers

• Numbers are grouped into 'periods'.

• Each period has three digits.

• Commas separate these periods.

• Example: 1,234,567 is easier to read.

Understanding Millions

The millions period is a crucial part of our number system, found to the left of the thousands period. It helps us organize and read very large numbers, grouping digits into millions, ten millions, and hundred millions. For example, in the number 345,678,901, the digits '345' are in the millions period, representing three hundred forty-five million.

Finding Place Value

Place value tells you the worth of a digit based on its position in a number. For example, in 1,234,567,890, the digit '2' is in the hundred millions place. Understanding this helps us read and write very large numbers, even up to billions.

Base ten blocks visualize place value: 3 hundreds, 4 tens, 9 units.

Introducing Billions!

We've explored thousands and millions. Now, let's meet billions! A billion is a huge number, equal to one thousand millions. For example, the Earth's population is currently over 8 billion people.

Billions of people: A global population distribution.

Billions Examples

• Earth's population is over 8 billion people.

• Our Milky Way galaxy has billions of stars.

• Over 5 billion people use the internet.

• Major movie franchises earn billions worldwide.
