Vocabulary List revisited

Vocabulary List is one of my 3 original apps I published about a year ago.

Get Vocabulary List here.

This is a great app to carry a list of vocabulary to study where ever you go. Log new words, quiz yourself. At the $1 price tag, there are very few downloads. Everyone (including me) wants free stuff.

I want this to be useful for students! Now it is free:
Get Vocabulary List Lite here.

The $1 version now has an additional feature to import/export lists to your gmail account. You can send yourself a pipe-delimited vocabulary|definition list you crafted on your computer and then study on your phone.

Visual Math Quiz

In America, we test kids every year and say they FAIL. Yes, many of them do fail. They don't know their stuff expected at their grade. But we never bother to teach them well in the first place.

There are poor teachers. There are problems at home. There is little motivation.

We test them but we don't go over test with them. Why are old Iowa Test/ACT/SAT with answers and explanation not given to kids so they may learn what they did wrong? After all, the whole point of education is learn?

Here is the Visual Math Quiz of basic arithmetic. I may make it a series to cover math topics beyond basic arithmetic.

Why is it easier to learn the basic operations if you WATCH a teacher do it on the board? That's because the teacher can do it one step at a time. Sure, you can tell the teacher to do another example, but the teacher can only do so much. So, the calculator can do this, but it doesn't show you the steps.

How about you enter 2 numbers and select an operation and see it carry out the steps.

How about clearing up the confusion of integer arithmetic in number line demonstration. See, adding means count to the right, subtraction means count to the left.
