Objective

By the end of this lesson, you will be able to apply geometric concepts to design and create paper airplanes.

Materials and Prep

• Sheets of paper
• Pencils
• Rulers

No prior knowledge is required for this lesson.

Activities

1. Introduction to Geometry: Start by discussing the basic concepts of geometry, such as points, lines, and angles. Explain how these concepts are used in designing paper airplanes.
2. Exploring Different Shapes: Discuss different shapes, such as squares, rectangles, triangles, and circles. Show how these shapes can be used to create different parts of a paper airplane, like wings and tail.
3. Measuring and Drawing: Teach the student how to measure and draw different shapes accurately using a ruler and pencil. Have them practice drawing wings and tail of a paper airplane using specific dimensions.
4. Testing and Adjusting: Let the student fold and assemble their paper airplane design. Encourage them to test their creation by flying it and observe its flight characteristics. Discuss how adjustments in shape and dimensions can affect the flight performance.
5. Design Challenge: Challenge the student to create their own unique paper airplane design using their knowledge of geometry. Encourage them to experiment with different shapes, sizes, and folds to optimize flight performance.

Fifth Grade Talking Points

• "Geometry is the branch of mathematics that deals with shapes, sizes, and properties of figures."
• "Points are the basic building blocks of geometry. They are represented by a dot and have no size or dimension."
• "Lines are made up of points and extend infinitely in both directions. They can be straight or curved."
• "Angles are formed when two lines intersect. They are measured in degrees."
• "Squares have four equal sides and four right angles. They are symmetrical."
• "Rectangles have four sides with opposite sides being equal in length. They also have four right angles."
• "Triangles have three sides and three angles. The sum of angles in a triangle is always 180 degrees."
• "Circles are perfectly round shapes. They have a radius, diameter, and circumference."
• "When designing paper airplanes, we can use different shapes to create wings, tail, and body."
• "By adjusting the dimensions and shape of the wings and tail, we can affect the flight performance of a paper airplane."
