Key Concepts

  • Identifying 2D shapes
  • Counting sides and corners
  • Distinguishing between shapes based on their attributes

Learning Objectives

  • Students will be able to identify circles, squares, rectangles, triangles, kites, and stars.
  • Students will be able to count the number of sides and corners of each shape.
  • Students will be able to describe the defining attributes of each shape (e.g., a square has four equal sides).

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what shapes they already know. Introduce the concept of 2D shapes being flat like a piece of paper. Show the Miacademy video '2D Shapes: Part 1 - Math for Kids!'
  • Shape Exploration (15 mins)
    After the video, discuss each shape individually. For each shape: 1. Draw the shape on the board. 2. Ask students to count the number of sides. 3. Ask students to count the number of corners. 4. Describe the shape's unique attributes (e.g., 'A circle has no sides or corners.').
  • Shape Sorting (10 mins)
    Provide students with pre-cut shapes (circles, squares, rectangles, triangles, kites, and stars). Have them sort the shapes into groups based on their attributes (e.g., all shapes with four sides). You can have them glue the shapes onto construction paper in organized groups.
  • Shape Hunt (10 mins)
    Have students look around the classroom for examples of the 2D shapes they learned about. For example, a clock might be a circle, or a book might be a rectangle. Have them share their findings with the class.

Interactive Exercises

  • Shape Matching Game
    Create a simple matching game where students match pictures of shapes to their names.
  • Shape Building
    Provide students with toothpicks and marshmallows or playdough. Have them use these materials to build the 2D shapes they learned about.

Discussion Questions

  • What is the difference between a square and a rectangle?
  • Can you think of real-world objects that are shaped like a circle, square, rectangle, triangle, kite, or star?
  • How many sides does a triangle have? How many corners?
  • What shape has no sides and no corners?

Skills Developed

  • Shape recognition
  • Counting

Educational Standards

CCSS.Math.Content.1.G.A.1:Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes. CCSS.Math.Content.1.G.A.2:Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as "right rectangular prism.")
