Laminate your game board & cards - wipe clean after each game
Something I learned when I worked in the school system: if you want to make one game board and change out the game with each lesson laminate everything. I made one board, then I took index cards and decorated them. The board and cards were laminated so that I could use a sharpie (any color will work), when I finished with that game I used fingernail polish remover to erase the writing and changed the cards. This works great for us because we are very limited on resources.
