Place Value, Expanded Form, and Number Line

This week has been all about place value. We started our discussion with the importance between the words "place" and "value". We practiced writing numbers in word and expanded form, and spent lots of time practicing saying numbers correctly. In 4th grade, the expanded form changes a bit so that we focus more on the multiplication involved. For example, 28,437 would look like (2 x 10,000) + (8 x 1,000) + (4 x 100) + (3 x 10) + (7 x 1). Today, we focused on putting these numbers on a number line and correctly identifying the intervals of the number lines.
