父さんは昨日家の前庭に家事があったので、私の手伝いが欲しかった。
My father had some housework

to do in the front yard, so he asked my help.

お草花が植えたかったし、雑草が来ないのため造園織物も据えた。
We planted some new flowering plants, and also laid out some landscape fabric to prevent weeds.

それをした間に、息子も子供の電気車で乗って遊んだ
While we were doing that, my son was having fun driving a children’s electric vehicle.
