When I've taught children (and adults!) with little programming
experience, I usually have a single import for all the things I want
them to use, something like:
from my_defined_functions import *
at the beginning of every script, usually named for the class I'm teaching.

I use the iPython Notebook now for these things.

in my universal import script I have the turtle imports, usually with
both from turtle import * and import turtle, so I have a choice.

I also make a data structure, a simple wrapper around dict, which I
call Struct, defined as:
class Struct(dict):
def __getattr__(self,name):
try:
val=self[name]
except KeyError:
val=super(Struct,self).__getattribute__(name)
return val
def __setattr__(self,name,val):
self[name]=val
then I can do:
x=Struct(a=5,b=10)
x.c=50
x['this']='that' # or access like a dict
