Objective

By the end of this lesson, you will be able to apply geometric concepts and principles to create and analyze Lego structures.

Materials and Prep

• Lego bricks and plates
• Ruler or measuring tape
• Pencil and paper

Prior knowledge of basic geometric shapes and their properties is helpful.

Activities

1. Build a square:

   • Use Lego bricks to construct a square shape.
   • Measure the length of each side using a ruler or measuring tape.
   • Record the measurements.

2. Create a rectangle:

   • Build a rectangle using Lego bricks.
   • Measure the length and width of the rectangle.
   • Calculate the area and perimeter of the rectangle.

3. Construct a triangle:

   • Build a triangle using Lego bricks.
   • Identify the type of triangle (equilateral, isosceles, or scalene).
   • Measure the lengths of the sides and record the measurements.

4. Build a 3D shape:

   • Choose a 2D shape (square, rectangle, triangle) and build multiple copies of it using Lego plates.
   • Stack the 2D shapes to create a 3D structure.
   • Describe the properties of the 3D shape (number of faces, edges, and vertices).

Eighth Grade Talking Points

• "Geometry is a branch of mathematics that deals with shapes, sizes, and properties of figures."
• "In this lesson, we will explore geometric concepts using Lego bricks."
• "We will start by building squares and measuring their sides."
• "Next, we will construct rectangles and calculate their area and perimeter."
• "Then, we will build triangles and identify their types based on side lengths."
• "Finally, we will create 3D shapes by stacking 2D shapes and describe their properties."
• "By applying geometry to Lego building, we can have fun while learning about shapes and their characteristics."
