Key Concepts

  • Fractions as parts of a whole
  • Decimals as another way to represent fractions
  • The relationship between tenths, hundredths, and the whole number 1
  • Using a number line to visualize fractions and decimals

Learning Objectives

  • Students will be able to convert fractions with denominators of 10 and 100 to decimals.
  • Students will be able to identify the decimal equivalent of a fraction on a number line.
  • Students will be able to explain the relationship between tenths and hundredths.
  • Students will be able to write decimals in word form to the hundredths place.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about fractions and decimals. Ask guiding questions to prompt class responses. Briefly review the concept of fractions as parts of a whole and how it applies to the base-ten system.
  • Video Viewing (5 mins)
    Play the 'Relating Fractions to Decimals Song' video. Encourage students to sing along and pay attention to the visuals, especially the number line representation.
  • Discussion (10 mins)
    After the video, initiate a class discussion about the key concepts presented in the song. Focus on the relationship between fractions and decimals, place value (tenths and hundredths), and the number line representation.
  • Interactive Activity: Number Line Challenge (15 mins)
    Provide students with pre-drawn number lines (ranging from 0 to 1). Give them different fractions (e.g., 3/10, 7/10, 25/100, 68/100) and ask them to: a) Mark the corresponding decimal point on the number line. b) Write the decimal equivalent of the fraction.
  • Wrap-up and Assessment (5 mins)
    Review the key concepts one last time. Administer the multiple-choice or fill-in-the-blank quiz to assess student understanding.

Interactive Exercises

  • Number Line Matching Game
    Create cards with fractions and their decimal equivalents. Have students match the cards by placing them on a number line. For example, a card with '1/2' should be matched with a card with '0.50' and placed halfway between 0 and 1 on the number line.
  • Decimal Detective
    Provide clues about a specific decimal number (e.g., 'I am greater than 0.2 and less than 0.4. I have a 3 in the hundredths place'). Students must use their knowledge of place value and number lines to deduce the decimal number (0.33).

Discussion Questions

  • What is a decimal, and how is it similar to a fraction?
  • How does a number line help us understand decimals and fractions?
  • Can you give an example of a fraction and its decimal equivalent?
  • Why is it important to understand the relationship between fractions and decimals?
