### 5th Grade Mathematics Lesson Plan: Geometry
#### Topic: Properties of Shapes and Coordinate Planes
**Objective:**
By the end of this lesson, students will be able to:
1. Identify and describe the properties of different geometric shapes.
2. Understand and use coordinate planes to locate points.
3. Plot and interpret points on a coordinate plane.
**Materials Needed:**

- Rulers
- Protractors
- Geometry shapes set (triangles, quadrilaterals, circles, etc.)
- Coordinate plane worksheets
- Geometry-related manipulatives (optional)
- Projector (for showing images/maps)
**Common Core Standards:**
- CCSS.MATH.CONTENT.5.G.A.1: Use a pair of perpendicular number lines, called axes, to define a coordinate system.
- CCSS.MATH.CONTENT.5.G.A.2: Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane.
- CCSS.MATH.CONTENT.5.G.B.3: Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category.
- CCSS.MATH.CONTENT.5.G.B.4: Classify two-dimensional figures in a hierarchy based on properties.

### **Lesson Plan**
**Introduction (15 minutes):**
1. **Warm-Up Activity:**
- Begin with a quick review of previously covered material related to shapes and their attributes.
- Brief discussion: Ask students to name different geometric shapes (e.g., triangle, square, rectangle, etc.) and their properties (e.g., number of sides, angles).
- Show visual aids of these shapes and discuss key properties.
2. **Learning Objective:**
- Introduce the day's objectives and explain what students will learn about properties of shapes and coordinate planes.
**Direct Instruction (20 minutes):**
1. **Properties of Shapes:**
- Use the whiteboard to draw different shapes and discuss their properties, such as the number of sides, angles, symmetry, and specific attributes (e.g., a square has four equal sides and right angles).
- Use geometric shapes set to provide a hands-on demonstration.
- Discuss categories and subcategories of shapes (e.g., all squares are rectangles, but not all rectangles are squares).
2. **Introduction to Coordinate Planes:**
- Draw a coordinate plane on the whiteboard.
- Explain the concept of the X-axis and Y-axis and how they intersect at the origin (0,0).
- Demonstrate how to plot points using coordinates (e.g., (2,3)).
- Show how to label the quadrants on the coordinate plane with a focus on the first quadrant for this lesson.
**Guided Practice (20 minutes):**
1. **Activity 1 - Properties of Shapes:**
- Distribute graph paper, protractors, and rulers.
- Provide different shapes drawn on the graph paper.
- Ask students to identify properties of each shape (e.g., length of sides, angle measurements).
- Group discussion to compare findings.
2. **Activity 2 - Coordinate Planes:**
- Distribute coordinate plane worksheets.
- Give students a set of points to plot on their coordinate planes.
- Walk through the process together: Example points: (1,2), (3,4), (5,6).
**Independent Practice (15 minutes):**
1. **Worksheet:**
- Provide a subsequent worksheet with more complex shapes and coordinate plane plotting questions.
- Ask students to complete the worksheet independently.
- Encourage students to check each other's work with a partner to ensure accuracy.
**Assessment (10 minutes):**
1. **Quiz:**
- A short quiz to assess understanding.
- Questions on properties of shapes and plotting points on the coordinate plane.
- Example: “Identify the properties of a given shape” or “Plot the point (4,5) on the coordinate plane.”
**Conclusion (5 minutes):**
1. **Review:**
- Summarize the key points of the lesson.
- Reiterate the importance of knowing properties of shapes and reading coordinate planes.
2. **Homework:**
- Assign a homework task that includes drawing and describing geometric shapes and several coordinate plane plotting problems.
3. **Closing Reflection:**
- Ask students to share one new thing they learned about geometry today.
- Collect feedback and answer any remaining questions.
**Extension Activities:**
- **Advanced plotting:** Introduce plotting points in all four quadrants.
- **Geometry art:** Create a piece of art using shapes and coordinate plane points.
