Lesson Plan: Mathematics - STEM

Grade: 3
Topic: STEM - Introduction to Geometry
Duration: 30 minutes

---

Objective

By the end of this lesson, students will be able to:

• Identify basic geometric shapes.
• Understand the properties of two-dimensional shapes.
• Create simple geometric patterns using various shapes.

---

Materials Needed

• Whiteboard and markers
• Geometric shape cutouts (triangles, squares, rectangles, circles)
• Colored paper
• Scissors
• Glue sticks
• Ruler

Lesson Outline

Introduction (5 minutes)

1. Greeting and Warm-up

   • Welcome students to the class.
   • Briefly discuss what STEM stands for: Science, Technology, Engineering, and Mathematics.
   • Ask students if they can name any shapes they see around them (e.g., in buildings, furniture, etc.).

2. Introduce Geometry

   • Explain that today’s focus will be on geometry, part of mathematics that deals with shapes and their properties.

Direct Instruction (10 minutes)

1. Introduction to Shapes

   • On the whiteboard, draw and label the following shapes:
     • Triangle
     • Square
     • Rectangle
     • Circle

2. Properties of Shapes

   • Discuss the properties of each shape:
     • Triangle: 3 sides, 3 angles.
     • Square: 4 equal sides, 4 right angles.
     • Rectangle: 4 sides, opposite sides are equal, 4 right angles.
     • Circle: No sides, no angles, all points are equidistant from the center.

---

Guided Practice (5 minutes)

1. Shape Identification
   • Show cutouts of different shapes and ask students to identify them.
   • Engage students by asking questions like, "How many sides does this shape have?" or "What shape is this if it has all equal sides?"

---

Independent Activity (8 minutes)

1. Pattern Creation

   • Distribute colored paper and scissors to students.
   • Instruct them to cut out at least one of each shape discussed.
   • Encourage students to create a pattern using the shapes they cut out (e.g., triangle, square, triangle, square).

2. Glue Shapes

   • Have students glue their shapes onto another piece of paper to display their patterns.

---

Conclusion (2 minutes)

1. Share Patterns

   • Ask a few students to share their patterns with the class.
   • Encourage positive feedback and discussion about the different patterns created.

2. Recap

   • Summarize what was learned about shapes and their properties.
   • Reinforce how geometry plays a role in everyday life.

---

Assessment

• Observe students during the guided practice and independent activity to assess their understanding of shapes and ability to create patterns.
• Evaluate the patterns created for correct use of shapes and creativity.

---

Additional Resources

• Educational websites for interactive shape games.
• Books related to geometry for further reading.
