N.2 Identify cubes

Exploring Solid Shapes

Children start learning about solid shapes by looking at real objects. Solid shapes are 3D, which means they have length, width, and height. A cube is a solid shape with flat faces and straight edges.

Example:
  • Blocks, dice, and small gift boxes are shaped like cubes.
  • Hold a cube and point to its corners and faces.
Note

Use real objects to introduce solid shapes. Let children touch, turn, and explore cubes to understand their shape better.

What Makes a Cube?

A cube is a solid shape with 6 square faces, 12 straight edges, and 8 corners. All faces are the same size. Learning these features helps children tell a cube apart from other 3D shapes.

Example:
  • Show how all sides of a dice are squares.
  • Turn the cube and count the 8 corners together.
Note

Compare a cube to other shapes like a ball or can. Emphasize that only the cube has square faces on every side.

Finding Cubes Around Us

Cubes are everywhere in daily life. Identifying cubes in the real world helps children connect math to familiar objects.

Try This:
  • Find cube-shaped toys, blocks, or boxes at home or in the classroom.
  • Play a “cube hunt” and make a pile of cube objects together.
Note

Encourage children to pick up and rotate the cube-shaped objects to feel the flat faces and corners.

Comparing Cubes with Other Solid Shapes

Children learn faster when they compare shapes. A cube is different from a sphere, cylinder, or cone because it has flat square faces instead of round or curved surfaces.

Try This:
  • Put a cube and a ball side by side. Ask, “Which one can roll?”
  • Compare a cube and a can. Ask, “Which one has flat squares?”
Note

Using simple comparisons helps children notice the special features of a cube and remember them.

Hands-On Learning with Cubes

Hands-on play builds strong shape knowledge. Children can stack, line up, and sort cubes to understand their shape and stability.

Example:
  • Stack cubes to make a tower and see how flat faces fit together.
  • Sort cube blocks from other shapes in a mixed block set.
Note

Stacking and sorting activities make learning active. Children also learn that cubes don’t roll because of their flat faces.

Talking About Cube Features

Describing shapes out loud helps children remember them. Use simple words like flat, corner, edge, and square face when exploring cubes.

Example Sentences:
  • “A cube has six square sides.”
  • “I can touch the eight corners of this cube.”
Note

Repeat and encourage children to use these words during play or sorting to strengthen vocabulary and understanding.
