My 7th grade students are in the middle of exploring fractions. They are currently researching the question:

**What are fractions and how can I add, subtract, multiply and divide them?**

I'm not sure how much instruction I want to give here. Is this intuitive? What can I do to make this more usable?

Applet with more instruction is here.

**Update**

John Golden:

@dcox21 @danielpearcy worth letting students adjust estimate afterfirst fraction is shown?

Good idea. Updated version.

I like the intent. Not sure it is so intuitive on the first use, but the pieces are there. Thinking that it may be best to do the problem in steps. First, I want students to show me that they understand 4/5; then I can ask them to show me 2/3 of 4/5. Not sure how much value the initial guesses will have, if the audience is intended to be students who already have trouble "seeing" fractions.
