Name the two-dimensional shape

Key Notes:

Introduction to 2D Shapes:

• What are 2D Shapes?
  • Explain that 2D means “two-dimensional.”
  • These shapes are flat and have only two measurements: length and width.
  • They don’t have thickness or depth.
  • Use real-world examples of flat objects like paper, tablet screens, the face of a clock, etc.

II. Common 2D Shapes and Their Properties:

• Circle:
  • Round shape with no corners and no straight sides.
  • All points on the edge are the same distance from the center.
  • Examples: coin, button, plate.
• Square:
  • Has four straight sides.
  • All four sides are equal in length.
  • Has four corners (vertices).
  • All four corners are right angles (like the corner of a book).
  • Examples: some tiles, faces of a cube.
• Rectangle:
  • Has four straight sides.
  • Opposite sides are equal in length.
  • Has four corners (vertices).
  • All four corners are right angles.
  • Examples: door, book, table top.
• Triangle:
  • Has three straight sides.
  • Has three corners (vertices).
  • Explain that triangles can look different (some sides can be the same length, or all different). Focus on the number of sides and corners.
  • Examples: slice of pizza, some road signs.
