Lesson Plan Title:
Grade 1 Mathematics Lesson Plan: Introduction to Place Value
Materials Needed:
– Base-10 blocks (units and tens)
– Place value charts
– Worksheets for practice
– Interactive whiteboard or chalkboard
– Number cards
– Counting objects (beans, buttons, etc.)
– Student exercise books
– Pencils
Learning Objectives:
By the end of the lesson, students will be able to:
1. Understand the concept of place value in two-digit numbers.
2. Identify the tens and units (ones) place in a two-digit number.
3. Represent numbers using base-10 blocks.
4. Write numbers in expanded form (e.g., 23 as 20 + 3).
Vocabulary:
1. Place Value – The value of a digit depending on its position in a number.
2. Units (Ones) – The rightmost digit in a number, representing how many ones are in the number.
3. Tens – The digit in the second position from the right, representing how many tens are in the number.
4. Digit – Any of the ten symbols used to write numbers (0-9).
5. Expanded Form – Writing a number to show the value of each digit (e.g., 23 = 20 + 3).
Previous Learning:
Students have previously learned to count up to 100 and recognise numbers. They have engaged in basic addition and subtraction activities with single digits.
Anticipated Challenges and Solutions:
– Challenge: Understanding the concept of tens and units.
Solution: Use concrete materials like base-10 blocks to visually and physically represent the numbers.
– Challenge: Distinguishing between the place value of digits in different positions.
Solution: Use place value charts and number cards to reinforce learning through visual aids.
Beginning Activities: (4 minutes)
1. Introduction: Greet the students and briefly explain the day’s topic, “Place Value.”
2. Activate Prior Knowledge: Ask students simple questions about counting and recognising numbers. “Can anyone tell me what numbers you see on this chart?”
Middle Activities: (32 minutes)
1. Direct Instruction (10 minutes):
– Demonstrate place value using base-10 blocks. Show a two-digit number (e.g., 23) using two ten-blocks and three unit blocks.
– Explain the place value positions: the left digit represents tens, and the right digit represents ones.
- Guided Practice (10 minutes):
- Show various two-digit numbers and ask students to represent them using base-10 blocks.
- Use the interactive whiteboard to display numbers and ask students to identify the tens and units.
- Independent Practice (12 minutes):
- Distribute worksheets where students practice identifying the place value and writing numbers in expanded form.
- Walk around the classroom to assist students who may need extra help.
End Activities: (4 minutes)
1. Consolidation: Summarise the day’s lesson by reviewing key concepts. Reinforce the idea that the position of a digit determines its value.
2. Exit Ticket: Have students complete a quick check by asking them to write the expanded form of a given number on a piece of paper and hand it in as they leave.
Assessment and Checks for Understanding:
– Observational assessment during guided practice.
– Worksheet completion to check independent practice understanding.
– Exit ticket for immediate understanding check.
Differentiation Strategies for Diverse Learners:
– Scaffolding: Provide more guided practice and use visual aids like place value charts and number cards.
– Extension: Offer advanced students more challenging tasks, such as representing three-digit numbers or exploring simple addition and subtraction involving tens and ones.
Teaching Notes:
– Encourage students to use the base-10 blocks to physically touch and move while answering to reinforce their understanding.
– Be patient with students who may struggle with abstract concepts like place value and provide plenty of encouragement and positive reinforcement.
– Ensure materials are accessible to all students, including those with physical disabilities who might need larger or more tactile-friendly manipulatives.
