Baseball Math!

My 7th graders have been busy studying factors and multiples to get ready for fractions. A few days ago, we did some baseball math. I first did this lesson with students last year and it took me forever to figure out the Baseball stats! 
The kids pick a year and write down fractions for the different stats; the number of home-runs divided by the number of times at bat. Or how many triples divided by the number of times at bat. The denominator stays the same for all four fractions and the numerator depends on the number of home-runs, triples, doubles, or singles. When they write down their fractions, they convert them into decimals and number of squares (for 0.03 it would be 3 squares). There is a 10x10 game board where the students fill in random squares with the number of HR (home-runs), 3B (triples), 2B doubles, and 1B (singles). When the squares are filled in, they use a spinner twice to help them locate a certain square on the game board (like Battleship in a way). If the square is empty, they have a strike, but if it has one of their symbols, they may have a run or be stuck on a base until someone else is up to bat. It took the students so long to figure out the fractions, we did not have much time to play. Next time, my plan is for them all to fill in stats for the same card and then they fill in their game boards differently and we play together. 
For the students who need more of a challenge, they can fill in another card and game board before playing. 
And we might need some chewing gum 'cause that is what came with those packages of baseball cards when I was a kid! At least for my brothers! I did not care about the cards, just the chewing gum! ;)
