Key Concepts

  • Shapes have defining attributes.
  • Objects with the same shape are similar, regardless of size or color.
  • We can group objects based on their shape.

Learning Objectives

  • Students will be able to identify and name basic shapes (circle, square, triangle, rectangle).
  • Students will be able to match objects based on their shape, regardless of size or color.
  • Students will be able to explain why objects with the same shape are considered similar.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what shapes they already know. Show them different shapes (circle, square, triangle, rectangle) using flashcards or drawings. Briefly discuss the characteristics of each shape.
  • Video Viewing (5 mins)
    Play the YouTube video "Learn Grade 1 - Maths - Matching By Shape Similar Figures". Ask students to pay attention to how the objects are grouped and matched.
  • Discussion (5 mins)
    After the video, discuss what they saw. Ask questions like, "What shapes did you see in the video?" "How did they match the objects?" "Were all the objects the same size? Did that matter?"
  • Shape Matching Activity (10 mins)
    Provide students with a worksheet containing various shapes in different sizes and colors. Have them draw lines to match the shapes that are the same. You can also use physical objects like blocks or cut-out shapes for a hands-on activity.
  • Wrap-up (5 mins)
    Review the concept of similar figures and how shapes can be the same even if they are different sizes or colors. Ask students to give examples of similar shapes they see in the classroom.

Interactive Exercises

  • Shape Sorting
    Provide students with a collection of objects (e.g., buttons, blocks, crayons) in different shapes. Have them sort the objects into groups based on their shape.

Discussion Questions

  • What are some shapes you see every day?
  • How are a big circle and a small circle the same?

Skills Developed

  • Shape recognition
  • Sorting and classifying
  • Visual discrimination

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.')
