Lesson Plan Title:
Grade 2 Mathematics Lesson Plan: Introduction to Place Value
Materials Needed:
1. Base-ten blocks (units, rods, and flats) or place value charts
2. Whiteboard and markers
3. Interactive place value chart (digital tool)
4. Worksheets with place value activities
5. Number cards (0-9)
6. Counters or beads
7. Projector or smartboard
Learning Objectives:
1. Students will understand the concept of tens and units.
2. Students will be able to identify and represent numbers up to 99 using place value.
3. Students will be able to decompose numbers into tens and units.
4. Students will demonstrate understanding by solving place value problems.
Vocabulary:
1. Place Value – The value of a digit depending on its position in a number.
2. Units (Ones) – Digits in the far-right position indicating values from 0 to 9.
3. Tens – Groups of ten units; the digit in the second position from the right.
4. Decompose – Breaking down numbers into tens and units.
5. Base-ten blocks – Tools to represent units (ones), rods (tens), and flats.
Previous Learning:
Students have previously learned to count and write numbers up to 99. They have basic addition and subtraction skills and can recognise and order numbers.
Anticipated Challenges and Solutions:
– Challenge: Understanding the concept of tens and units.
– Solution: Use concrete manipulatives like base-ten blocks to provide a visual and hands-on understanding.
– Challenge: Confusing the position of digits in two-digit numbers.
– Solution: Use place value charts regularly to reinforce the concept.
Beginning Activities (4 minutes):
1. Introduction to Objectives: Briefly outline the lesson objectives.
2. Activating Prior Knowledge: Ask students to count to 10 using fingers. Discuss how we bundle fingers into groups of tens when counting to higher numbers.
Middle Activities (32 minutes):
1. Direct Instruction (10 minutes):
– Introduce place value using a visual place value chart.
– Demonstrate how to represent numbers like 23 or 45 using base-ten blocks (2 rods and 3 units, 4 rods and 5 units).
- Guided Practice (10 minutes):
- Distribute base-ten blocks to students. Show a number (e.g., 36) and have students represent it using the blocks.
- Move around the classroom, checking for understanding and assisting as needed.
- Independent Practice (12 minutes):
- Hand out place value worksheets.
- Students to complete exercises that involve identifying the tens and units in given numbers and representing numbers with base-ten blocks.
- Use number cards for a short activity where students form numbers and decompose them into tens and units.
End Activities (4 minutes):
1. Exit Ticket: Students write down the number 47 and decompose it into tens and units on a piece of paper.
2. Review Objectives: Quickly recap the lesson’s objectives, asking volunteers to share their exit ticket answers.
Assessment and Checks for Understanding:
– Observational Assessment: Monitor student understanding during guided and independent practice.
– Worksheet Assessment: Review completed worksheets for correct decomposition and representation of numbers.
– Exit Ticket: Check exit tickets for quick understanding of place value at the end of the lesson.
Differentiation Strategies for Diverse Learners:
– Scaffolding: Provide additional support and manipulatives for students struggling with the concept.
– Extension: Challenge advanced students with three-digit numbers and ask them to decompose these into hundreds, tens, and units.
– Visual Learners: Use colour-coded base-ten blocks and charts.
– Kinesthetic Learners: More hands-on activities with manipulatives.
Teaching Notes:
1. Educational Value: This lesson builds foundational number sense, crucial for future mathematical concepts like addition, subtraction, and understanding larger numbers.
2. Tips for Effective Delivery:
– Use a variety of teaching tools to cater to different learning styles.
– Provide positive reinforcement and encourage peer support.
3. Accessibility Considerations: Ensure all manipulatives are easy to handle. Provide larger base-ten blocks or digital representations for students with fine motor difficulties.
By carefully planning and incorporating these elements, you can effectively teach Grade 2 students about place value in a clear, engaging, and inclusive manner.
