1. Can someone give me an example of a word problem involving the multiplication of two negative numbers?

2. I have to do the "make a model" activity with about 5 Tiger Cubs next week. I am sick of little wood models that you buy and the kids nail together (POUND POUND POUND) and then paint (dripping paint in car on the way home . . .). The model can be anything--wood, paper, clay, etc. Anyone have any interesting ideas for me? They have about an hour to do the project.

If you owe \$5 to two people, that would be the equivalent of having 2 x -5.

If you are forgiven a debt of \$5 to two people, that would be equivalent of having -2 x -5.

That's the best example I can come up with for a multiplication problem with two negative numbers.

No ideas on the model thing.

I just googled and found this webpage with some word problem examples of multiplying with negative numbers:

It's not great, since I generally show how multiplication works, then the word problems involve numbers that are negative, but I can't think of any in texts that just have two numbers (and not algebraic expressions), but here's an attempt....

You spend \$5 each day. How much did you have 4 days ago?

So (\$ spent)*(# days) = (-5)(-4) = 20

When my brother was a scout they sometimes did things like lace together pieces of leather to make a pouch or once they did a small macrame project (can't remember what it was) as a way to practice knots.

No help on the math...

No hammers or nails needed. :)
