Subject: Mathematics
Class: Primary 1
Term: Second Term
Week: 9
Age: 6-7 years
Topic: Two Dimensional Shapes
Sub-topic: Numbers 231-240, Skip Counting, and 2D Shapes
Duration: 40 minutes
Behavioral Objectives:
By the end of the lesson, pupils should be able to:
- Identify and count numbers from 231-240.
- Skip count in 2s, 5s, and 10s.
- Recognize two-dimensional shapes in their environment.
- Identify common objects related to two-dimensional shapes (e.g., square, circle, rectangle, triangle).
- Name household items that resemble two-dimensional shapes.
- Apply the concept of capacity in real-life situations.
- Solve simple quantitative reasoning problems related to the lesson.
Keywords:
Two-dimensional shapes, square, circle, rectangle, triangle, skip count, capacity, numbers 231-240, quantitative reasoning
Set Induction:
- Activity: Begin by asking pupils to look around the classroom and identify objects with shapes like squares, circles, rectangles, and triangles. Write their answers on the board.
- Rationale: This activity links the lesson content with real-life observations, making it more relevant and engaging for the students.
Entry Behavior:
- Pupils should already be able to count from 1-100 and understand basic shapes like squares, circles, rectangles, and triangles.
Learning Resources and Materials:
- Flashcards with shapes (square, circle, rectangle, triangle)
- Number charts (231-240)
- Household objects (or pictures) that demonstrate 2D shapes
- Whiteboard and markers
- Counting objects (e.g., coins, buttons) for skip counting exercises
Building Background/Connection to Prior Knowledge:
- Pupils are familiar with counting numbers 1-100.
- They have previously learned basic shapes and their properties (e.g., squares, circles, triangles).
Embedded Core Skills:
- Communication Skills: Pupils will express their understanding of shapes and counting.
- Critical Thinking Skills: Pupils will identify shapes and apply the concept of capacity in real-world situations.
- Problem-solving Skills: Pupils will apply their knowledge of skip counting to solve quantitative reasoning problems.
Learning Materials:
- Flashcards with shapes
- Pictures of household items (square, circle, rectangle, triangle)
- Number charts from 231 to 240
Reference Books:
- Lagos State Scheme of Work for Primary 1 Mathematics
- Lagos State Curriculum for Mathematics
Instructional Materials:
- Flashcards with shapes
- Whiteboard and markers
- Counting materials (coins, buttons)
- Household items or pictures representing 2D shapes
Content:
- Two-Dimensional Shapes (2D):
- A two-dimensional shape is a flat shape that only has length and width. These shapes can be drawn on paper or any flat surface.
- Examples of 2D shapes include:
- Square: A shape with four equal sides, like a chessboard.
- Circle: A round shape, like a tyre or a coin.
- Rectangle: A shape with four sides, where opposite sides are equal, like a door.
- Triangle: A shape with three sides, like a caution sign.
- Numbers 231-240:
- These are numbers in the series from 231 to 240.
- Students will learn how to count forward and backward from these numbers.
- Skip Counting:
- Skip counting is counting by numbers other than 1. For example:
- Count in 2s: 2, 4, 6, 8, 10, 12, etc.
- Count in 5s: 5, 10, 15, 20, 25, etc.
- Count in 10s: 10, 20, 30, 40, 50, etc.
- Skip counting is counting by numbers other than 1. For example:
- Capacity in Real Life:
- Capacity refers to how much something can hold. For example, a container can hold liquid or solid objects. Common examples of containers at home are cups, bottles, and bowls.
Examples:
- Square: The chessboard has many squares.
- Circle: A tyre or a coin is shaped like a circle.
- Rectangle: A door is shaped like a rectangle.
- Triangle: The C-caution sign is shaped like a triangle.
- Skip Counting:
- Counting by 2s: 2, 4, 6, 8, 10, 12…
- Counting by 5s: 5, 10, 15, 20, 25…
- Counting by 10s: 10, 20, 30, 40, 50…
