Jawaban:

My weekend was really fun. Brother and I went shopping. My sister bought a dress as a birthday presesnt for her friend. I bought a new pair of shoes, skateboard shoes. I bought shoes with my pocket money for ten months. I'm so glad I bought it myself. On sunday mornings, I wear these shoes. Then I skateboard all day. Those shoes are so comfortable. It was so much fun.

It's basically a copy of what you wrote ( btw check for spelling just in case :D ). If you didn't know, this is already in past tense!

and the pic I attached is info about Simple Past Tense / Past Simple Tense ( it's the same thing )

I hope I helped! Sorry if I got anything wrong ♡
