: Understanding the value of digits in decimal numbers.

Lesson Plan: Number, Money and Measure

Topic: Understanding the value of digits in decimal numbers

Level: Second Level

Curriculum Area: Mathematics

Curriculum for Excellence Experiences and Outcomes:

• I can extend the range of whole numbers I can work with and having explored how decimal fractions are constructed, can explain the link between a digit, its place and its value. (MNU 2-03a)
• I can use decimal notation for tenths and hundredths and partition decimals into their integral and fractional parts. (MNU 2-04a)
• I can solve problems requiring calculation, with simple fractions and decimal fractions using a range of methods, sharing my approaches and solutions with others. (MNU 2-09a)

Learning Intentions:

• To understand the value of digits in decimal numbers.
• To be able to partition decimals into their integral and fractional parts.
• To be able to solve problems requiring calculation with simple fractions and decimal fractions.

Success Criteria:

• I can explain the link between a digit, its place and its value in decimal numbers.
• I can partition decimals into their integral and fractional parts.
• I can solve problems requiring calculation with simple fractions and decimal fractions.

Resources:

• Whiteboard and markers
• Decimal place value chart
• Decimal number cards
• Money manipulatives
• Worksheets

Introduction (10 minutes):

• Begin the lesson by asking the students if they know what decimal numbers are and how they are different from whole numbers.
• Write the number 3.25 on the board and ask the students to identify the value of each digit.
• Use the decimal place value chart to explain the value of each digit in the number.
• Ask the students to identify the place value of each digit and explain its value.

Development (30 minutes):

• Distribute decimal number cards to each student and ask them to identify the value of each digit in the number.
• Use money manipulatives to demonstrate how decimal numbers are used in real-life situations.
• Ask the students to partition the decimal numbers into their integral and fractional parts.
• Provide worksheets for the students to practice partitioning decimals and solving problems with simple fractions and decimal fractions.

Plenary (10 minutes):

• Ask the students to share their answers to the worksheet questions and explain their reasoning.
• Review the learning intentions and success criteria with the students and ask them to reflect on their learning.
• Provide feedback to the students on their progress and identify areas for improvement.

Assessment:

• Observe the students during the lesson and provide feedback on their understanding of the value of digits in decimal numbers.
• Assess the students’ ability to partition decimals into their integral and fractional parts and solve problems with simple fractions and decimal fractions through the worksheets provided.
