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.
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.
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.
