Understanding Midpoints and Number Lines

This video tutorial teaches how to find the midpoint between two numbers using a number line. It begins with a review of counting by tens and hundreds, then explains benchmark numbers and how to read a number line. The concept of a midpoint is defined, followed by practical examples, including finding the midpoint between 800 and 900. The tutorial emphasizes the importance of midpoints in solving real-world problems.

What is the purpose of finding a midpoint on a number line?

• To find the exact center between two numbers

• To determine the average of two numbers
