Why not? Because at some point some things are simply a drill item. Once
you understand count bys (2,4,6,8) you memorize your math facts and do it
with TIMINGS. Not everything can be taught efficiently (or even well)
through discovery learning. Lord knows I've seen 4th graders that don't
know their multiplication math facts. Teaching them functions withing small
sets of simple multiplication facts was very limiting. Let's not even get
into addition math facts - that they did not know. These are TYPICAL 4th
graders taught using - you guessed it - discovery math.
Please don't.
You want to make it fun? Use Precision Teaching and chart their math fact
progress. When they are done, show shooting stars, a rocket blasting off -
maybe the class can have a small party when a student finishes all math
facts. If they get a high score on a particular timing, add an extra part
of a picture so they can see it quicker. There are all sorts of behavioral
motivators that can be incorporated into the XO.

Re the "Math API," really consider what's going to make the difference and
leverage the XO's use.
Merely making a "flash cards" or "Quizing" program doesn't really buy you a
whole lot. You don't need a computer to create Flash cards or quizes.
The benefits of doing things on a computer should be exploited. This is
where most drillware fails to be educational or motivational. In the XO's
case you have the other advantage of a platform that will easily support
collaborative work.
Instead of a flash card or a quiz that shows a diagram and asks a question,
why not single or shared apps that allow students to manipulate objects and
symbols to arrive at an answer. Much more interactive, constructive and
developmentally appropriate, since kids in the OLPC age group are born
experimenters. Give them 2D environments to manipulate to take them way
beyond the digital equivalent of a printed piece of cardboard.
Also Brian, remember that we're in a conceptual design and prototyping stage
in an 18 month long development timeline. At this point one of the most
useful things that can be done is to create "10 small apps that don't make
it out of a beta stage"
A technologist's first instinct is to "build the tech!" When you are
building educational software (and really any content-based software,)
prototyping various approaches and running them by your target audience is
crucial to the success of your development effort.
Those 10 small apps that test various methods of displaying objects and
symbols for students to experiment with object manipulation and formulas
tell you which directions to move in to make the right software to go beyond
alpha down the appropriate delivery for the content and the audience :-)
