Understanding Decimals and Fractions

This video tutorial for fourth-grade math covers the expansion of decimals into hundredths using a meter stick as a visual aid. It explains place value, expanded notation, and number bonds. The tutorial demonstrates how to locate decimals on a number line and decompose them into tenths and hundredths. It also includes shading exercises to visualize fractions and decimals, emphasizing the small size of hundredths compared to tenths.
