Comparing Fractions with the Same Denominator

This lesson teaches how to compare fractions with the same denominator by reasoning about their size. It begins with a comparison of whole numbers and introduces the use of symbols for greater than and less than. The lesson then uses fraction models to compare fractions like 3/10 vs 7/10 and 4/8 vs 1/8. Real-world examples, such as comparing parts of a sandwich eaten, are used to illustrate the concept. The lesson concludes with a summary of the key points covered.
