Original sentence: The mighty rotor pops the helicopter into the air, lets it hover or fly any way it wants.
Correction (clear and simple): The mighty rotor lifts the helicopter into the air and lets it hover or fly wherever it wants.
Step-by-step explanation for a 7-year-old:
- The comma between the two actions is not the best choice. We need the word and to join the two actions the rotor does: lifts and lets.
- "Pops" is okay, but "lifts" is a little clearer—rotors lift the helicopter up.
- Use "wherever" instead of "any way" to mean "in any place or direction." (If you keep "any way," it must be two words: "any way.")
- "Hover" means to stay still in the air, like a hummingbird stopping in one spot.
- "Rotor" is the big spinning part on top that makes the helicopter go up and move around.
Another short child-friendly version: The strong rotor lifts the helicopter up and lets it hover or fly anywhere.
