Build, Try and Change

Olly needs a tall tower and a bridge for a toy car. Children learn the builder's cycle: build it, try it, change one thing and try again. They choose materials that stay put instead of rolling away, find out that a wide bottom helps a tower stand, and build and improve their own block bridge at home.

What learners will discover

  • Choose materials that work for building, such as blocks that stay put rather than balls that roll.
  • Test a building to find out if it works (does it stand, does it hold the toy?).
  • Change one thing after a test and try again, following the order build, try, change, try again.
