Hello, Emma! Sorry if it took me a while to check these wonderful homework here. I'll give some corrections and I suggest it would be better if you write it like this.

I stay in the bedroom while my family prepares for the party. When they are ready, they will call me togo out of the room. They will sing the birthday song to me, give me presents and we eat the cake together. After that, we play games.

You constructed it good but please be mindful of the correct punctuation marks. It must be put correctly. Good job.
