3 Simple Rephrasings for an 8-year-old: 'Road rollers squash the bumps so the road is flat and smooth'

Here are three simple ways to say that sentence:

1. Road rollers press down the bumps so the road becomes flat and smooth.
2. The heavy roller pushes the bumps down and makes the road even and smooth.
3. Big road rollers flatten the bumps, leaving a smooth, level road.

How road rollers do this (step-by-step) — explained for an 8-year-old:

1. First, the road is bumpy and rough.
2. The road roller (a very heavy machine with a big round drum) drives over the bumps.
3. The heavy drum rolls and presses the bumps down.
4. After the roller passes several times, the road becomes flat and smooth.

Tip: Use any of the three rephrasings when you want to say the same idea in a different way.
