Lesson Plan Title:
Grade 1 Mathematics Lesson Plan: Introduction to Place Value
Materials Needed:
– Base ten blocks (units and rods)
– Place value charts
– Whiteboard and markers
– Worksheets with place value exercises
– Interactive place value games or apps (if technology is available)
– Flashcards showing different two-digit numbers
Learning Objectives:
By the end of the lesson, students should be able to:
1. Understand the concept of tens and units.
2. Identify the place value of each digit in a two-digit number.
3. Compose and decompose numbers up to 99 into tens and units.
4. Use base ten blocks to represent numbers.
Vocabulary:
1. Place Value: The value of a digit based on its position in a number.
2. Unit: Single-digit numbers (0-9).
3. Ten: A group of ten units.
4. Decompose: Break down a number into its place value parts.
5. Compose: Combine units and tens to form a number.
Previous Learning:
Students have previously learned how to count up to 100, recognise numbers, and engage in simple addition and subtraction using objects and pictorial representations. This foundation will help them grasp the concept of grouping numbers into tens and units.
Anticipated Challenges and Solutions:
1. Confusion between tens and units: Use visual aids such as base ten blocks and place value charts to reinforce understanding.
2. Difficulty in deconstructing larger numbers: Provide plenty of practice with smaller numbers first and gradually move to larger ones.
Beginning Activities (4 minutes):
– Introduction: Briefly explain what place value means. Use a simple analogy, like grouping pencils into boxes of ten, to illustrate the concept.
– Activity: Show a number, for example, 23, on the whiteboard and ask students to identify the tens and units visually.
Middle Activities (32 minutes):
1. Direct Instruction (10 minutes):
– Use base ten blocks to physically show the difference between tens and units.
– Demonstrate how to decompose a number into tens and units, e.g., 45 as 4 tens and 5 units.
- Guided Practice (10 minutes):
- Distribute base ten blocks and place value charts to students.
- Walk them through several examples, first as a class and then in small groups.
- Encourage students to represent numbers like 36, 58, and 74 using their blocks.
- Independent Practice (12 minutes):
- Hand out worksheets with place value exercises.
- Allow students to work individually to identify and write the tens and units of given numbers.
- Circulate the room to provide assistance and feedback as needed.
End Activities (4 minutes):
– Exit Ticket Activity: Each student receives a flashcard with a two-digit number. They must write the number of tens and units on their flashcard before they leave.
– Review: Quickly recap what was learned about tens and units and how to decompose numbers.
Assessment and Checks for Understanding:
– Observations during guided and independent practice.
– Review of completed worksheets to check for accuracy.
– Exit tickets to quickly assess understanding of place value concepts.
Differentiation Strategies for Diverse Learners:
– Scaffolding: Provide additional visual aids and manipulatives for students who need more support.
– Extension Activities: Offer more complex numbers for advanced students or ask them to create their own place value problems for peers.
– Peer Support: Pair struggling students with those who grasp the concept well for additional peer tutoring.
Teaching Notes:
– Educational Value: Understanding place value is fundamental to mastering more complex mathematical concepts. It underpins all further work with larger numbers and arithmetic.
– Effective Delivery Tips: Use plenty of hands-on activities and visual aids to make abstract concepts concrete. Encourage questions and always relate new information to what students already know.
– Accessibility Considerations: Ensure that all manipulatives and worksheets are accessible to students with disabilities. Use large print, tactile base ten blocks, and consider digital resources for visually impaired students.
