Lesson 2: Numbers up to 100,000

Here is a PDF version of the lesson.

Here is a PDF version of the workbook containing lots of practice.

In this math lesson you will learn about numbers up to 100,000.

You will discover their properties (for example, that any number added to 0 is that number). You will learn about the importance of the place value of each digit within the number.

In this lesson, we demonstrate how to add and subtract numbers up to 100,000, as well as how to multiply and divide them vertically.

It is important to understand how to “borrow” a digit or how to “carry” a digit.

The lesson teaches how to group the digits based on their place value in order to do operations with numbers faster and without using a calculator.
