Ordering Numbers Up to 100

The video tutorial explains how to order numbers using an open number line. It begins with an introduction to the concept of ordering numbers and demonstrates how to arrange three numbers, 87, 31, and 40, from least to greatest. The tutorial then introduces the open number line as a tool for visualizing number order and places these numbers on it. Finally, the video covers a more complex example with five numbers, showing how to use the open number line to order them effectively.
