Adding Tenths and Hundredths

In this lesson, the teacher introduces the concept of adding fractional parts of tenths and hundredths. The lesson reviews how to convert tenths to hundredths by multiplying both the numerator and denominator by ten. The teacher explains that fractions can only be added if they have the same denominator, and demonstrates how to convert fractions to have a common denominator. Several practice problems are provided to reinforce the concept, and the lesson concludes with a recap and encouragement to review the material if needed.
