My chem teacher told us that the group one elements react differently than other metals?
For example, the problems were...
NaOH-->
KOH-->
and apparently the answers are not Na+OH or NaO+H2O ?
Anyone know why?

As said before it is because of the one electron in their outer electron shell but the answer he gave is wrong because if you were to write the names of these compounds it would almost be common sense as to the other reactant.
Na+H2O→NaOH + Hydrogen gas
K+H2O→KOH + Hydrogen gas
Those elements have to be stored under oil because otherwise they would form hydroxides, not oxides.

due to one electron in their outermost shell group one elements are highly reactive and they r very unstable such as sodium thats why element is placed in oil, sodium reacts with oxygen in air and form its oxide
Na donate electron and form Na+
and that electron is accepted by oxygen in air
4Na + O2 -----> 2Na2O
Na2O+H2O -----> 2 NaOH
