Properties Foldable

Today we reviewed the California State Algebra standard, Properties.  Another long-time foldable.  I usually go foldable crazy at the beginning of the year.


I tried to do the properties, real numbers, and a properties card sort in one period.  Did not work.  Okay once I cut the card sort.




Made 4 Math Monday – Foldables (Expressions, PEMDAS, Decimals, Fractions and Integers)

I have been making foldables for many years after I found Dinah Zike’s books for sale online.  I own several of them and was so excited to see them used in textbooks, too.  Here are few of the basic ones I do every year, and one new one I tried that is really fun.


After seeing information on I Speak Math, I added the word “turn-around” to some of the phrases.

Order of Operations

Decimal Operations

Started making some pre-written instead of making the students write everything.  I took some key words out.

Fraction Operations

And the coolest one of all, from the Fantastic Flexible Foldables, Integer Infinity Square by Carol DeFreese .  There are some amazing ones at this website http://home.centurytel.net/cdefreese/foldables/.  I took out some information…next time I will take out some more.

*****UPDATE 9-16-15  Looks like Carol DeFreese’s page is gone!!!  I found a PDF of the foldable on my computer here:  integers infinity foldable.  Unfortunately, it has been a while since I last made it, so I hope you can figure it out from my pictures.  Sorry!  ALSO, I would edit the wording…not crazy about the whole war thing.  I can’t remember if I put that in, or if it was on her foldable.
