Before practising, it sounds a good idea to realise the fact of:

Do you know the difference between Past Simple and Past Continuous?

I was reading the newspaper WHEN the telephone rang.

My mother was having a shower WHEN hot water finished.

Josh was playing football WHEN it started to rain.

Someone knocked at the door WHILE I was making a sandwich.

Two cars crashed WHILE I was walking the dog.

There was a power cut WHILE I was listening to music.

New tricky aspect:             Before / After

07:30 Get up                                                        I got up before I had a shower.

07:40 Have a shower                                         I brushed my teeth after I had my breakfast.

07:50 Get dressed                                              or you can also say: 

08:00 Have breakfast                                        Before I had a shower, I got up.

08:05 Brush my teeth                                        After I had my breakfast, I brushed my teeth

08:10 Comb my hair

08:15 Go to school
