Ann  has  6  small  square  pieces  of  paper.  2  squares  are  grey.  Ann  cuts  the  2  grey  squares  in  half  with  a  diagonal  line  from  one  corner  to  the  other.

a. What  shapes  does  she  have  now?  

b.            How  many  of  each  shape  does  she  have?  

c. Use  all  the  shapes  with  no  overlaps.  Draw  at  least  2  different  ways  Ann’s  set  of  shapes  might  look.  What  fraction  of  the  figure  is  grey?
