Math Games offers online games and printable worksheets to make learning math fun. Kids from pre-K to 8th grade can practice math skills recommended by the Common Core State Standards in exciting game formats. Never associated learning algebra with rescuing animals or destroying zombies? Time to think again!

Kids learn better when they're having fun. They also learn better when they get to practice new skills repeatedly. Math Games lets them do both - in school or at home.

Teachers and parents can create custom assignments that assess or review particular math skills. Activities are tailored so pupils work at appropriate grade levels. Worksheets can be downloaded and printed for classroom use, or activities can be completed and automatically graded online.

The main thing I feel is that I'm not organizing my mind and my derivations as clear as I could, because I don't have the best "math habits". I feel like if I could develop better math habits, I could significantly improve both my time efficiency and the quality of my thinking.

To show what I mean, I'll compare it with the skill of writing: I used to write in a very unstructured way: I simply started writing with some vague idea of what I wanted to write. Then after having written a paragraph, I would generally be somewhat confused. After 2 paragraphs I'd be more confused. Eventually I didn't have a clear idea of what to write because my mind was so cluttered, as if all my neural pathways were firing un-synchronously, creating a senseless mess. I have now solved this by developing better habits: I started making bullet point lists of my papers that contained the central argument, before I wrote the actual paragraphs. I then wrote one paragraph at a time, focusing only on what that particular one had to convey. Also, I developed a more structured way of structuring paragraphs: rather than just "writing it", I thought about the first sentence separately, and then its relation to the second, and so on... After developing these better habits, I felt like my brain had a much more "lean" and "uncluttered" process it was following, as if my neural pathways fired synchronously, in harmony.

I feel like right now with maths, I am in a similar stage that I used to be with writing. I understand math concepts, and I know how to do many of the methods, and I'm progressing. But whenever I'm working on a math problem, I feel like I'm getting confused, not just because the problem is new and difficult, but because my mind is cluttering and confusing itself, as if I don't have a "process" that is optimized for figuring out new math.

One way this shows, though I don't know if its a cause or a symptom, is that my derivations look like a plate of spaghetti. Yet if I try to write things more structuredly, I'm held back even more, because it puts me into a very "fearful" and paralyzed state of mind (fearful to write something wrong).

So I'm looking for habits that I can develop that will, just like I did with my writing process, turn my "cluttered" mind, into a "harmonic" one. That doesn't mean math will suddenly be easy, but at least the difficulty will be due to the complexity of the math, rather than due to me working against myself.

So I'm interested if any of you have experienced this same thing, and whether there have been specific habits or other things that have helped you overcome this.

To give an example of something that recently has actually helped me somewhat: Whenever I now derive an intermediate result, I write big boxes around it, with a big dense filled circle in the corner, in order to signify that it is an important result. This somewhat declutters my mind, because I no longer have to wade through all the intermediate steps, looking for the important stuff.

ps. I hope this question is not too general or subjective. I know that subjective questions are not the purpose of math.stackexchange, but I thought: there certainly are some objective principles behind what kind of habits work and don't work. And I wouldn't be surprised if I'm not the only one who could benefit.

I think this is a great question and you've already made an important step in addressing the problem - realizing that you are not satisfied with your math working process and searching for ways to improve it. Here are some ideas and suggestions which I found helpful:

Play with simplified models. This is something I really learned in graduate school and I wish I would have been told explicitly much earlier. If you are facing a problem that you have no idea how to approach and you feel paralyzed, try to work on a simplified (even trivial) model. For example, let's say you need to prove some statement about a linear map $T$ on some vector space $V$ and you have no idea what to do. Can you solve the problem if you assume in addition that $V$ is one-dimensional? Even better, if $V$ is zero-dimensional? Can you do it if $T$ is diagonalizable? If you are asked to prove something about a continuous function, can you do it if the function is a particularly simple one? Say a constant one? Or a linear one? Or a polynomial? Or maybe you can do it if you assume in addition it is differentiable?

Applying this idea has two advantages. First, more often than not you'll actually manage to solve the simplified problem (and if not, try to simplify even more!). This will increase your self-confidence and help you feel better so that you won't give up early on the harder problem. In addition, the solution of the simplified problem will often give you some hints on how to tackle the general one. You might be able to perform an induction argument, or identify which properties you needed to use and then realize those properties actually apply in a more general context, etc.

EDIT: I misunderstood the OP at first, and the first half of my answer gives advice on how to approach proving an unknown problem. I then tie this into the organizational question the OP is really asking below the line.

Every time you see a theorem, first seriously commit yourself to finding a counter example. Find almost-counterexamples that show why every assumption in the problem is necessary. Then for each of those almost-counterexamples find an example that is extremely similar, except satisfies the assumption the counterexample was missing. Now you're ready to prove the theorem or read its proof, and in all likelihood you're already close to the proof.

One day in his office, I happened to mention Bezout's theorem which basically says that two curves of degree $m$ and $n$ respectively intersect in $nm$ points. He says he never heard of it and seems galvanized by it. He jumps up and heads to the blackboard, saying "Let's see if I can disprove that" Disprove it?! "Wait a minute!" I say, "that theorem is nearly two centuries old! You can't disprove anything... really..." As he begins to working on some counterexamples at the blackboard I see my well-meant words are simply static.
