Ordering and Comparing Decimals

This video tutorial covers the 5th grade math standard of comparing and ordering numbers, focusing on decimals. It explains a three-step process for comparing decimals: aligning decimal points, adding zeros for missing place values, and comparing whole numbers and decimals. An example is provided to illustrate these steps. The video also details the process of ordering decimals, which involves similar initial steps, followed by ranking numbers and rewriting them in order. An example is given to demonstrate this process.
