friday

Today was a quite relaxed day because in the morning there was a solar eclipse. At this time I was in school and there we got special glasses with which we could look into the sun directly without destroying our eyes. All in all this happening was quite unspectacular because only a part of the sun was invisible and so the sun looked like a fat half moon. However because of this incident we had less lessons. :)
In the evening a friend of my mum came to visit us and because of that my mother cooked a real good wok. After the (using "the" isn't really wrong, but it sounds more natural without it) dinner I made did some maths exercises and now I am a bit depressed because a) I feel like I forgot everything from the math lessons we just did one month ago
and b) it is Friday evening and I sit alone at home. But at the moment my friends are either ill or on vacation and I do not want to go out alone. So maybe next week I'll do it again. We will see.

"Do" is a general verb that describes any action. "Make" is a synonym with "create". Saying you made some maths excercises makes it sound like you made some questions to give to other people to solve.

"Maths" is British and Australian English. "Math" is American English. You used both in this paragraph. Incidentally, "on vacation" is American English and "on holidays" is British and Australian English.

Friday

Today was quite a relaxed day because there was a solar eclipse in the morning. I was in school at the time and we got special glasses with which we could look into the sun directly without destroying our eyes. All in all the eclipse was quite unspectacular because only part of the sun was blocked and so the sun looked like a fat half moon. However, because of this incident we had fewer lessons. :)
In the evening my mother cooked a real good wok (not sure what a wok is) because a friend hers came to visit us. After dinner, I did some maths exercises and now I am a bit depressed because a) I feel like I forgot everything from the math lessons we just had one month ago
and b) it is Friday evening and I am sitting at home alone. But at the moment my friends are either ill or on vacation and I do not want to go out alone. So maybe next week again. We will see.

thanks for the correction
