Taking Apart & Rebuilding

Observe that an object made of a small set of pieces can be disassembled and made into a new object, understanding that the pieces still exist

What a learner can do afterwards

  • Explain that taking apart an object and rebuilding it uses the same pieces in a new arrangement
  • Describe how the pieces themselves don't change even though the object looks different
  • Give an everyday example of reusing materials to make something new

The lesson

Some toys are made of small pieces, like building bricks. When you take the toy apart, the pieces do not disappear. They are still there, just not connected anymore.

TowerPiecesCar
The same bricks make a tower, then loose pieces, then a car.
Try it together

Mia built a tower out of 8 bricks. She took the tower apart and used all 8 bricks to build a little car. She did not add new bricks or throw any away.

Tap each block and count out loud.
Good to know

Before you build something new, count your pieces first and after. The number should stay the same. Only the shape changes.

Taking a thing apart does not lose the pieces. The same pieces can build something brand new.
