Lesson Plan Title:
Grade 1 Mathematics Lesson Plan: Introduction to Addition
Materials Needed:
– Number cards (1-10)
– Counters (beans, buttons, or small blocks)
– Addition flashcards
– Whiteboard and markers
– Worksheets with simple addition problems
– Interactive addition game (digital or board game)
Learning Objectives:
By the end of the lesson, students should be able to:
1. Understand the concept of addition as combining two groups of objects.
2. Add numbers up to 10 using physical counters.
3. Represent simple addition problems symbolically (e.g., 2 + 3 = 5).
Vocabulary:
1. Addition: The process of combining two or more numbers to get a total.
2. Sum: The result of an addition problem.
3. Plus: The symbol (+) used to indicate addition.
4. Equals: The symbol (=) that shows the result of an operation.
5. Counters: Objects used to help count and solve math problems.
Previous Learning:
Students have previously learned to count objects accurately up to 10 and recognise numbers 1-10. They have been introduced to basic concepts of grouping and comparing quantities.
Anticipated Challenges and Solutions:
1. Some students may struggle with the concept of combining groups. Solution: Use plenty of physical manipulatives like counters and work through numerous examples.
2. Students may find it hard to transition from using objects to symbolic representations. Solution: Provide gradual steps from concrete to abstract thinking with ample guidance.
Beginning Activities (4 minutes):
1. Greet students and explain that today we will learn how to add numbers.
2. Quickly review counting from 1 to 10 as a warm-up.
3. Introduce the term “addition” and relate it to combining groups of objects.
Middle Activities (32 minutes):
1. Direct Instruction (10 minutes):
– Demonstrate addition using counters. Show how combining two groups of objects results in a new total.
– Write a simple addition equation on the whiteboard (e.g., 2 + 3 = 5) and explain each part of the equation.
- Guided Practice (10 minutes):
- Distribute number cards and counters to students.
- Present several addition problems orally (e.g., “Show me what 1 + 2 looks like using your counters”).
- Walk around the room to monitor and assist students as needed.
- Independent Practice (10 minutes):
- Provide worksheets with simple addition problems (e.g., 1 + 2, 3 + 2).
- Allow students to solve problems using counters if necessary.
- Interactive Game (2 minutes):
- Conclude the middle section with a quick digital or board game focusing on addition to reinforce learning through play.
End Activities (4 minutes):
1. Quick Review:
– Ask a few students to share a problem from their worksheet and explain how they solved it.
- Exit Ticket:
- Each student completes a quick addition problem on a piece of paper (e.g., 4 + 1 = ?).
- Collect the papers to assess understanding.
Assessment and Checks for Understanding:
– Observation during guided practice.
– Worksheet completion.
– Exit ticket responses.
Differentiation Strategies for Diverse Learners:
– For struggling students, offer additional one-on-one support and allow them to continue using counters.
– For advanced students, provide slightly more challenging addition problems or introduce the concept of “doubles” (e.g., 2 + 2, 3 + 3).
– Use visual aids and auditory support for learners who need more reinforcement.
Teaching Notes:
– Emphasise the importance of students verbalising their thought process (“I have 2 beans here and 2 more there, so all together I have 4 beans”).
– Make sure to frequently check in with all students to ensure understanding, especially during transitions from concrete to abstract representations.
– Ensure materials are accessible to all students, including those with fine motor skill difficulties (e.g., larger counters).
This lesson introduces addition in a fun and interactive way, providing strong foundational skills necessary for future arithmetic proficiency.
