Wheel and I
The wheel is man’s greatest invention. Without it, our life will be difficult. You
can find the wheel all around you.
Early Man was our ancestor. He lived thousands of years ago. He
lived like wild animals. He walked from one place to another. He
carried loads on his shoulders. He pulled heavy loads on a sledge.
He faced a great difficulty as there were no roads.
