Comparing Decimals: Test Your Knowledge

The video tutorial introduces the lineup and cover method for comparing decimals. It explains how to align decimals using placeholders to ensure they are the same length, making comparison easier. The cover method is used to compare decimal places, and strategies for handling equal decimal values are discussed. The tutorial also covers comparing decimals with whole numbers and explains decimal equivalence and naming. The lesson concludes with practice problems for students.
