Lesson 1: Numbers to 1,000,000 Review
Getting Started
During this unit, you're going to review our place value system and work with really big numbers. Along the way, you'll compare, order, and round big numbers from the millions place to the thousandths. You'll also learn about something called "power counting" that lets you count to really big numbers quickly.
To get started, watch the music video at the following web link to review how to read and write numbers to the millions place. Pay attention to how to say big numbers and where to place the commas when writing them.

Things to Know
- A factor is a number that is multiplied by another number to get a product.
- A multiple is the product of a number and another number.
- A prime number is a number greater than 1 that has only 2 factors, the number itself and 1 (such as 2, 3, 11).
- A composite number is a number that has more than 2 factors (such as 4, 6, 12).
- The number 1 is neither prime nor composite.
- The only even prime number is 2. All other even numbers have 2 as a factor.
- Expanded form expresses a number by showing the value of each digit. In expanded form, 4,532 is 4,000 + 500 + 30 + 2.
- Expanded notation, or super expanded form, expresses a number by showing each digit multiplied by its place value. In expanded notation, 4,532 is (4 × 1,000) + (5 × 100) + (3 × 10) + (2 × 1).
Skills
- Read and write numbers from 1,000,000 to thousandths using base-10 numerals, number names, and expanded form
Introducing the Lesson
During this unit, your child will review what he already knows about place value in our number system and will extend his understanding to include decimals to the thousandths. He will compare, order, and round numbers from the millions to the thousandths and will write these numbers in multiple forms. He will also learn about powers of ten and exponents and will explore Roman numerals.
Explain to your child that this first lesson focuses on reading and writing numbers to the millions place. If you think that he would benefit from a comprehensive review of place value and the base-10 number system, allow him to watch the video at the following web link.
