In this lesson, students explored the concepts of tenths and hundredths, learning how to represent these fractions both visually and as decimal numbers. They practiced identifying the place value of digits in given numbers, such as 2.47, where the tenth digit is 4, and 9.35, where the tenth digit is 3. The lesson also included exercises using a place value chart and a number line to reinforce these concepts, highlighting the importance of understanding decimal places in mathematical calculations.
