Decimals Lesson Plan for Teachers

Lesson Title:Decimals

Lesson Objective: Students will understand the concept of decimals and be able to compare and order decimals.

Materials:

  • Whiteboard and markers
  • Base-10 blocks or manipulatives
  • Decimal worksheets

    • Introduction (5 minutes): Begin the lesson by asking the students if they have ever used money before. Write the following examples on the board: $1.25, $2.50, $3.75. Ask the students what they notice about these numbers.

    Direct Instruction (15 minutes):

    1. Introduce the concept of decimals and explain that a decimal is a way to represent a number that is between two whole numbers. 2. Show the students how to read and write decimals using base-10 blocks or manipulatives. 3. Explain that the decimal point separates the whole numbers from the fractional parts. The number to the left of the decimal point is the whole number and the numbers to the right of the decimal point represent the fractional part of the number. 4. Show the students how to compare and order decimals. Explain that when comparing decimals, you look at the digits to the right of the decimal point, starting with the first one. If the first digit to the right of the decimal point is the same, then you look at the next digit, and so on.

    Guided Practice (15 minutes):

    1. Have the students work in pairs and use base-10 blocks or manipulatives to represent different decimals. 2. Give the students a few examples of decimals and have them compare and order them. 3. Assist students as needed.

    Independent Practice (15 minutes):

    1. Give the students decimal worksheets to work on. 2. Monitor their progress and offer assistance if needed.

    Closure (5 minutes):

    1. Have the students share their answers with a partner. 2. Review the key concepts of the lesson and ask the students to explain in their own words what they have learned today.

    Assessment: Collect the decimal worksheets and use them to assess the students’ understanding of the concept. Give feedback and offer additional practice as needed.

    Note: Remind students that when comparing and ordering decimals, they should compare only the digits to the right of the decimal point.
