What you will learn

  • 1Identify geometric shapes in real-world objects
  • 2Match everyday objects to their geometric shape names

Mini Lesson

Geometric shapes are all around us in the real world. A door is a rectangle. A pizza is a circle. Honeycomb cells are hexagons. Even 3D shapes appear in everyday objects: a soup can is a cylinder, a die is a cube, and an orange is a sphere. Learning to recognize these shapes and their properties helps us connect geometry to the world we live in.

2D Shapes in Real Life

  • Rectangle: doors, books, phone screens, windows.
  • Circle: pizzas, coins, clocks, wheels.
  • Triangle: yield road signs, roof shapes, wedges of cheese.
  • Hexagon: honeycomb cells, some bolts and nuts.
  • Square: tiles, some windows, chessboard squares.

3D Shapes in Real Life

  • Cube: a die, a sugar cube, some boxes.
  • Sphere: an orange, a basketball, a globe.
  • Cylinder: a soup can, a paper towel tube, a drum.
  • Cone: a party hat, an ice cream cone, a traffic cone.

Words to know

Shape

The form of an object — like a circle, square, or triangle

e.g. A clock face has a circle shape.

Geometry

The math of shapes and their properties

e.g. Geometry helps us name shapes.

Real world

The places and objects we see every day

e.g. I find shapes in the real world.

Property

A feature of a shape, like number of sides or angles

e.g. Triangles have the property of 3 sides.

Side

A straight edge of a shape

e.g. A square has 4 sides.

Look around your learning space or your home. Try to name the geometric shape of every object you see. You will find shapes everywhere!
