Ordering and Comparing Decimals

This video tutorial for fifth graders covers ordering decimals, starting with a warm-up exercise to determine the truth of statements about decimal values. The teacher explains how to compare decimals by aligning place values and adding zeros for clarity. Students practice filling in blanks with numbers between given decimals and discuss using number lines for comparison. The lesson includes an activity to order decimals from least to greatest, emphasizing the importance of place value alignment. The session concludes with a synthesis of the concepts learned.
