Responses to different posts:
Just the notion of being "productive" is modern. If you
insist on being "productive", your only real option is to
produce babies.
Perhaps so, perhaps we're just not speaking the language, but I would think anything that one can do to make survival less work or more certain for a primitive group would be helpful, and I could consider that to be productive activity. Adding to their population without a proportional addition to their food supply would be counter-productive, unless their food supply significantly exceeds their needs.
They probably don't have written
language, you could do that, but it's probably a negative to
their culture, since oral cultures are much richer.
Oral culture is fine, but if you introduce a little basic technology into their lives, that knowledge will be better preserved by written materials -- of course, I'm assuming, probably optimistically, that reading and writing will be taught to future generations AND that they'd need that to preserve the technological information, which would likely be pretty basic and subject to pretty easy oral communication.
The following were good answers, for the most part, except for skipping the part where you observe and see what their needs are -- it may well be the case that saving labor is not a concern, and I'm assuming that if health-improving / survival aids are introduced, the island can support the increased longevity / infant survival / etc with adequate food.
So here's what I'd do in no particular order:
1. Learn the language
2. Scout the entire Island for natural resources
3. Introduce simple devices like the Archimedes Screw,
lever, water wheel, and other labor saving devices, etc...
(too long a list, I'm a history buff)
4. Work on creating paper from wood pulp. Make glue from
milk as bonding agent.
5. Attempt to give them written language and mathematics
6. Personal hygiene, and if I was successful in creating
glass lenses for magnification, show them bacteria.Depending on natural resources available--Sure they'd have
seaweed and sand.6. Show them how to make potash by burning seaweed and
distilling it.
7. Create a kiln and get to work showing them how to make
glass from silica and potash/ or quartz/potash.
8. Increase the yield of their crops by using the potash as
a fertilizer.
9. If limestone deposits were available I'd show them how
to make concrete.
10. If clay deposits were around introduce them to
pottery.
11. If they had indigenous animals, I'd pass on leather
working and tanning.
12. With metal deposits, show them how to craft metal
tools. (pottery has to come first, to forge metal you must
first have ceramic).
13. Time permitting (I'm probably old and dead by now). I'd
continue the progression from bronze age up to industrially
revolution giving them electricity, steam-power, etc...
14. If if found a wife, I would of course try to be a good
father and pass on as much of myself to my children.I would also be extremely careful to make sure their
technology didn't exceed their wisdom, and I'd do nothing to
remove their reverence of nature. I would not introduce the
concept of money. I would not create weapons for them, even
though I know how, unless they were in danger from other
tribes.>I would not introduce the concept of money. I would not

To this response, if it's serious (I expect not), I would remind everyone what the introduction of alcohol into American Indian life accommplished -- an exaggerated incidence of alcoholism (exaggerated compared to the incidence of the disease in the society introducing the alcohol to them).
