Unit 18 — Walking Somewhere

Walking Somewhere

Dan walked on the sidewalk.

Sometimes he stepped over dirt or puddles.

Once, he tripped on a crack in the sidewalk.

At a corner, he stopped at the curb and waited for traffic to pass.

Then he crossed the street by walking in the crosswalk.

Once he took a shortcut across a parking lot.

When he could, he ran because he was late.

He crossed a busy street by using a pedestrian overpass.
