Just did two fraction animations:

Do they work OK? Any suggestions?

I don't have any *real* suggestions, but I just found a single spelling mistake for Interactive Fractions; 'Fourtieth' should be 'fortieth'.

Other than that, no mistakes.

In the Match the Fraction game, why don't equivalents apply? For instance, five sixths. I made 10 twelths, and it didn't work. Same with two quarters, I tried a half, and then I tried 4 eighths, but neither worked.

Pretty good, nonetheless.

I think that's OK. 2/4 isn't *the same* as 1/2, it's just an equal amount.

The x1 and x2 names seem a bit strange. (eg. Twenty-first, fifty-second, etc.) But then again, twenty-oneth sounds odd as well, so I don't know. But very nice pages overall.

Why did the vector cross the road?

It wanted to be normal.

Thanks! Will fix and then "publish".

aarrh! the only thing that annoys me, is you keep calling these things animations they're applications, not animations

I think an "application" is something bigger, like a spreadsheet, word processor, etc.

Perhaps there is no correct name for this. "Manipulative" sounds horrible.

Application needn't be big, but either way its a better description than animation

These are great!

The only thing that didn't work particularly well for me was the little green arrows next to 'Slices:'. Sometimes they didn't want to do anything, and I had to click a few times for them to respond.

EDIT:

Oooh, and some of the fractions containing a nine need and extra 'e'.

i.e. 'ninteenths' should be **'nineteenths'**.

'twenty-ninteenths' should be **'twenty-nineteenths'**
