Key Concepts

  • Shapes have different outlines.
  • Sides are the straight lines that make up a shape.
  • Angles are where two sides meet.

Learning Objectives

  • Identify different shapes, including triangles, squares, rectangles, circles, hexagons, trapezoids, rhombus and pentagons.
  • Count the number of sides of a shape.
  • Count the number of angles of a shape.
  • Describe shapes based on their number of sides and angles.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about shapes. Show them different shapes and ask them to name them. Introduce the terms 'side' and 'angle'.
  • Video Viewing (7 mins)
    Watch the YouTube video 'Learn Sides and Shapes | Math for Kids | Geometry | Kids Academy'. Encourage students to pay attention to how the video defines sides and angles and identifies different shapes.
  • Review and Discussion (8 mins)
    After watching the video, review the key concepts. Ask students to define 'side' and 'angle' in their own words. Go through each shape mentioned in the video (triangle, circle, hexagon, trapezoid, square, rhombus, pentagon) and ask students to identify the number of sides and angles.
  • Worksheet Activity (10 mins)
    Distribute a worksheet with different shapes on it. Have students count the number of sides and angles for each shape and write the numbers down. You can also have them identify the name of the shape.
  • Wrap-up (5 mins)
    Review the answers to the worksheet. Ask students what they learned about shapes, sides, and angles. Reiterate the importance of shapes in our everyday lives.

Interactive Exercises

  • Shape Scavenger Hunt
    Have students look around the classroom or their homes and find objects that are specific shapes. For example, find something that is a square, a circle, or a triangle. They can then share what they found with the class.
  • Shape Building
    Provide students with toothpicks and marshmallows (or playdough). Have them use these materials to build different shapes. This will help them visualize the sides and angles of each shape.

Discussion Questions

  • What is a side?
  • What is an angle?
  • Can you name some shapes that you see around you?
  • How many sides does a triangle have?
  • How many angles does a square have?
