Lesson Title:Dividing Decimals

Lesson Objective: Students will be able to divide decimals with confidence and accuracy.

Materials:

  • Whiteboard and markers
  • Decimal worksheets
  • Base-10 blocks
  • Rulers
  • Calculator

    • Introduction (5 minutes):

  • Begin by reviewing the concept of decimals and place value.
  • Write the number “0.25” on the board and ask students to identify the whole number and the decimal part of the number.
  • Review the importance of understanding the place value of the decimal point when dividing decimals.

    • Direct Instruction (20 minutes):

  • Provide students with base-10 blocks and have them create decimal numbers.
  • Have students practice dividing decimal numbers using the base-10 blocks.
  • As they work, circulate the room and provide individual assistance as needed.
  • Introduce the process of dividing decimals using the example of 1/0.25 = 4. Explain how to move the decimal point in both the dividend and the divisor to get a whole number division and then how to move the decimal point in the quotient.

    • Guided Practice (20 minutes):

  • Provide students with decimal worksheets and have them complete a set of problems together as a class.
  • Go over the answers together, discussing any misconceptions or difficulties that students may have had.

    • Independent Practice (20 minutes):

  • Give students additional decimal worksheets to complete on their own.
  • Encourage students to check their work and ask for assistance if needed.
  • Provide students with rulers and calculators, have them measure the length and width of an object, divide the measurements to find the ratio and explain the meaning of that ratio.

    • Closure (5 minutes):

  • Review the key concepts covered in the lesson, such as the importance of understanding the place value of the decimal point when dividing decimals.
  • Give students an opportunity to share any strategies or tips they found helpful during the lesson.
  • Preview the next lesson and the related homework.

    • Assessment:

  • Observe students during independent practice to assess their understanding of the concepts taught during the lesson.
  • Collect and review completed worksheets as a form of summative assessment.
  • Observe students during their measurement activity and assess their ability to divide decimals correctly and understand the meaning of the resulting ratio.

    • Note: The above plan is a general outline and may need to be adapted depending on the specific needs and capabilities of the students in your class.
