Laws of Exponents

Every time I teach a unit on Polynomials (I know with my population of students) that I will need to start off going over the different Laws of Exponents.  In the past it always turned out to be a jumbled mess of notes that the students could never use or refer back to because you pretty much needed deciphering key just to understand it.  I tired a good handful of different foldables to get the information across but it just never worked.  I gave up and went on a google search to find someone way smarter than me who had already figured out what I couldn't.  Lo and behold Mrs. Williams came to the rescue with an awesome foldable, check out her blog!

Here are my instructions on how to put it together and the problems I used...

Materials Needed:
2 - 8 1/2" x 11" sheets of paper (2 different colors)
Favorite writing utensil  

Start with one of your colored sheets.  Fold it in half and cut it.  Then fold one of the halves in half and cut it again.  You will need 2 of the strips you just made.

                                          So now here are the supplies each student will need!

Take the large sheet of paper and turn it so it's landscape, fold it in half, and then fold it in half again.  It should be folded like an accordion.  Lay it on the desk so that it looks like a W when you look at it from the front. (This is super important!)

Grab the middle part of the W and cut it into 4 equal sections just until the fold. (If you don't cut to the fold the smaller strips will be hard to weave in and out.)

Now lay it back down on the table, again so it's a W, and weave the two smaller pieces in.  The center should look like a checker board.  Now you are done!


The magic to this foldable is if you put the two center pieces together, to make a point in the middle, you can pull the two pieces of paper apart to reveal a secret section.  This foldable always blows the kids minds!


Here is how I used it for the Laws of Exponents.
