Re: fourth grade geometry question???

The way I would approach this, and the way I anticipate a grade four
student should approach this is with imagination and examples. Try
some shapes (with a drawing program, with some sticks, etc.) Look at a
variety of examples and find one that fits the properties listed.
Take a parallelogram and say -what if I take these edges in a different
order?
Do I still have pairs of sides of equal length? What changes, what is
the same?
Doing this kind of playing around, and asking what if, is good
mathematics. Giving examples in a reference book does little to assist
the essential learning which can happen here. In fact, it feeds a
misperception of what mathematics is, and what children can do in
mathematics.
There may be a gap in communicating this sense of play, and
experimentation to children (and parents) - but the goal is great and I
encourage this approach.

I know you posted this last week but I am in the same boat. My 4th
grader as a geometry sheet for homework and I am lost. We do not have
a book to go by either. What is wrong with this system?? It has been
almost 20 yrs. since graduated much less did geometry. I am looking to
fing out what type of shape has four sides that are not equal.
