Uh, do you really need to use a computer? Running Mathematica?"

I would like to get your opinion as I see that you are a well cited
author of over 1100 documents on the Mathematica site.

Historically, experiments at higher educational levels to introduce a
computer algebra system into a math course have resulted in consequences
like this:
1. Students, on average, resented having to learn "something else" (i.e.
using computer program) that wasn't "on the final".
2. On average they learned "no less" than students in the control group
not using computers. But "no more" either.

We are now wondering whether introducing computers will work for
kindergarten students (in 2013) learning number shapes. Two significant
changes. (a) much younger students (b) a different attitude toward
computers/smart phones -- these having been ubiquitous.

Now I am hardly an expert in very early childhood education, but I have
seen some games aimed at children. Your game sounds pretty boring, but I
have seen something like it. Showing 4 ducks. Click on each one. Game
says "4 ducks" and shows a "4". Another requires tracing out of the
digits in the right directions of the strokes.

These are probably directed to children of age 3 with access to iPad or
similar. Children of age 5 in the US who cannot count to 10 and/or think
that 3 is two backwards C's stacked, are probably rare.

However, I am not actually >> objecting << to the educational
experiment. At worst you will be exposing children to a boring game that
they will simply not play.

What I am pointing out is that better software technology for all the
parts needed is so readily available and cheap. Using Mathematica seems
totally ill-advised. Possibly depriving kids of human contact --
Johnny, you have to learn your 3's. Sit in the back of the car and use
the computer..

Just because something Could Be Done with Mathematica does not mean
(a) it should be done with Mathematica. (b) should be done at all.
