Exploring Fractions and Decimals on a Number Line

The video tutorial explains how to use number lines to understand tens and hundreds. It begins with a review of dividing a number line into equal parts to represent tens and tenths. The concept of tenths is illustrated with examples, showing how to identify points on a number line. The tutorial then introduces hundredths, explaining how to further divide tenths into hundredths. Examples are provided to demonstrate how to locate points using hundredths. The video concludes with a final example and encourages practice with tens and hundreds on a number line.
