Good Coaches know how to play the game.
If you're going to coach, read the rules. Know how the game works. Discover the strategy of the game. Your team looks to you not only to help them with the math, they want to know what you know about MathGym 1-D.
Unfortunately most people don't learn to play a game by reading the rules, they learn by playing. Somebody needs to take the time to go through the "How to Play" portion of the website. When you have gone through the tutorials, PLAY THE GAME. After you understand how to move smoothly around the board, then you can teach someone else. MathGym 1-D requires a different type of thinking. It's not merely about answering a few math questions, but rather about knowing the answer you seek and discovering how to mathematically express that answer using the tiles you have been dealt. For instance, 12 is another way of saying 3 X 4, or 3 X 2 X 2, or (5 + 1) X 2, and so on.
Tell your players that the object of the game is to accumulate more money than their opponents. It doesn't matter which direction they go, as long as they keep making money.
