Today's version has been a while coming. There was a good deal of debugging to do once I set this little quiz up. There's a long way to go still, but I think now everyone has some idea where I'm going with this. At this point, the main directions for this project are:

1. Questions that aren't quite so straightforward. For example:

A group orders 2 pizzas and has some leftover from each. 1/6 of one of the pizzas is left, and 4/9 of the other pizza is left. Show how much of a whole pizza they have when they put the leftovers together to take home, as a single fraction.

In this case, the final fraction is unknown; the player will have to type in the numerator and denominator once all the pizza is served.

I'm also going to have to make changes to accommodate questions like:

3 people order 1_2/3 pizzas. Show how to divide this amount into equal servings for the three people, and show a single fraction that represents each serving.

3/8 of a pizza is leftover. From this, someone eats an amount equal to 1/5 of a whole. Show the amount that remains, as a single fraction.

3/8 of a pizza is leftover. Someone eats 1/5 of what is left. Show the amount that remains, as a single fraction.

2.  An aspect of the game that actually teaches, rather than merely presenting. As I show this to other teachers and we discuss it, it becomes obvious to me that this is more of a presentation tool than a teaching tool. In play mode, you can easily show how fractions are added, and I think it makes an effective visual for that, on a smartboard or elsewhere. But in quiz mode, there's nothing that gives you a clue as to whether you're on the right track or not; you'll only pass the quiz if you already know everything you need to know, or if you have a whole lot of luck. I have plenty of ideas for improving this, but it will have to wait a bit.

In the meantime, enjoy the latest version, and as always, feel free to give me any suggestions. The end goal is to have a free fraction teaching tool that really works.
