Decimals

Lesson

You may have used units, tenths and hundredths blocks in class to build numbers. Now we're going to look at how to build numbers using numerals (written digits). We will use number expanders and place value tables to help us do this.

Let's watch a video to get started.

Remember!

When we write numbers, the position (or "place") of each digit is important.

Demonstrate an understanding of place value in whole numbers and decimal numbers from 0.01 to 100 000, using a variety of tools and strategies (e.g., use numbers to represent 23 011 as 20 000 + 3000 + 0 + 10 + 1; use base ten materials to represent the relationship between 1, 0.1, and 0.01)
