Comparing and Ordering Decimals

The video tutorial focuses on the fifth-grade concept of comparing and ordering decimals, specifically addressing Texas standard 5.2b. Using a problem from the 2017 released STAAR test, the instructor guides students through identifying a list of decimals that is not ordered from least to greatest. The video covers strategies for aligning decimals by place value and adding zeros to simplify comparison. Each list is analyzed in detail, with list C identified as incorrectly ordered. The tutorial concludes with a review of the correct order for all lists.
