I you have x + i/f = d - 5, it would be great to be able to subtract i/f rather than multiplying by f and dividing by i. I know this isn't taught in the 5+ version, but would it be possible to make it allowable anyway?

Make it possible to make your own avatar. I don't like any of the offered ones. The avatars are all dark and disturbing if you want more parents to go for this make the images more kid friendly.

Our school is looking into replacing our expensive and hard to manage laptops with Chromebooks. App availability is somewhat spotty, though, and I see DragonBox as the main headline app, so it would be great to have it available. (Or better yet, an HTML5 version so we don't have to worry quite so much about platform.)

Just a grammar fix for the last congrat's page.

Perhaps do a new power thing, showing that dragging a to -a turns it into the spiral galaxy. Many kids would probably intuit it, and get there by trial and error, but showing it like I said would help kids with difficulty with abstraction, or those who hadn't been introduced to negative numbers.

When you finish all the worlds, enable an in-app purchase that has for instance 20 new worlds. Purpose: makes the kid practice more. I would be happy to pay 1-2 dollar per world.

Level 5 should be able to slide the negative one die on top of f to make it -f (and combine) before moving to the opposite of the equation. Level 5-17?).

Level 5 - perhaps in addition to double clicking to clear 1/-1 or object/ opposite object fractions (which seemed random at points because we couldn't tell which one to click to make it turn over consistently), students could combine the number and its opposite to get a negative one die or -1.

I'd like to be able to make my own levels, to use for solving problems from other sources, for instance. It would be a great way to work through a problem before solving it on paper.

If a student enters a color piece when a b&w should have been entered, they get stuck.

It is great that you have plans for release on Windows Phone. We hope that it will be available soon. Thanks!

Where the fractions are object/opposite object or night object/object could have it turn into a dark 'one' die so that students can understand it can be -1 instead of not able to simplify.

I dont know exactly how to do it, but i would like to take the reality in building a house, meassuring a distance or throwing a ball, and to create a connection between the important mechanics of solving an equation and the important skill of understanding to what problems you need to use what equations. My 7 years old kid. has finnished your first app and did found the second one and has completed level 8. (He likes math and strctures). I am now wondering how i can help him taking the next step and what that would be.

Level 3-19 You should be able to add 2/c + -2/c directly to get zero instead of having to multiply both by c and then add the opposite.

I would like to see the avatar/profile saved in Game Center or something and show up on whatever device is used, iPad, iPhone, iPod...

I teach 3rd grade. I only have one I-pad. My students work hard to meet goals that earn playing time with Dragon Box2. While this game is perfect for them, I am addicted, too. Although this game remains a challenge for my students, I am craving the next challenge.

One suggestion. I would love a tally that keeps count of the times I beat the game: my words for "solved in fewer moves." Maybe at a certain tally point my dragon could spit fire or fly.

When you have bought one app you should have been able to upgrade insted of bying new apps as the kids are growing. It becomes to expensive.
