Mathematics Lesson Plan: Place Value
Grade Level
Year 2 (Grade 2)
Duration
30 minutes
Learning Objectives
By the end of the lesson, students will be able to:
- Understand the concept of place value.
- Identify the value of digits in two-digit numbers.
- Represent numbers using base-ten blocks, diagrams, and written forms.
Materials Needed
- Base-ten blocks (units and rods)
- Place value charts
- Whiteboard and markers
- Worksheets with place value exercises
- Flashcards with two-digit numbers
Lesson Outline
Introduction (5 minutes)
- Begin the lesson by asking students if they know what place value means.
- Engage the class in a brief discussion about numbers they see in everyday life (e.g., on houses, in their age, etc.).
- Explain the terms "tens" and "ones" and how they relate to the position of digits in a number.
Direct Instruction (10 minutes)
- Place Value Chart Activity:
- Draw a place value chart on the whiteboard with two columns labeled "Tens" and "Ones."
- Write a two-digit number on the board (e.g., 34) and guide students in identifying the digits’ values based on their positions.
- For example, in the number 34, the 3 is in the tens place and represents 30, while the 4 is in the ones place and represents 4.
- Base-Ten Blocks Demonstration:
- Use base-ten blocks to visually demonstrate the concept.
- Show students how one rod represents ten and each unit represents one. Build the number 34 using the blocks.
Guided Practice (10 minutes)
- Group Activity:
- Divide students into small groups and provide each group with base-ten blocks.
- Assign different two-digit numbers to each group (e.g., 21, 48, 56).
- Instruct students to build their assigned number using the blocks and complete a place value chart showing the tens and ones.
- After they finish, groups will present their numbers to the class, explaining the place value of each digit.
Independent Practice (5 minutes)
- Distribute worksheets with exercises that require students to identify the place value of digits in given two-digit numbers and fill out a place value chart.
- Encourage students to represent numbers in expanded form (e.g., 34 = 30 + 4).
Closing (5 minutes)
- Review the key concepts of place value discussed during the lesson.
- Collect worksheets, and ask students to share one thing they learned about place value.
- Assign homework: students will find three two-digit numbers at home and write them in terms of tens and ones on a separate sheet of paper.
Assessment
- Evaluate students' participation in group activities and their ability to explain their findings.
- Review completed worksheets to assess understanding of place value.
Adaptations
- For students who may need additional support, provide one-on-one assistance during group activities or offer manipulatives to help them visualize the concept.
- Challenge advanced learners by introducing three-digit numbers and asking them to identify place values for hundreds, tens, and ones.
