Preparing for Halloween

On Friday October 27th Mrs. Barker will be taking her children to a Halloween Party.   She has offered to purchase the candy for the pinata.    There will be 30 children at the party.   Mrs. Barker went to London Drugs to buy the candy and noticed each bag of candy has 35 pieces.   How many bags will Mrs. Barker need to purchase so that every child at the party gets between 10 and 12 pieces of candy?  

Don't forget to share how you got your answer...

How many pies?

Mrs. Barker has offer to bring pumpkin pie to Thanksgiving dinner at her mother's.   There will be 19 people at dinner.   One pie can be cut into 8 pieces.   How many pies do I need to make?

Also, some people in my family love my pie and like to have 2 pieces and one of the people coming is a baby who won't be able to eat my pie.

Can you help me?  Please respond by commenting below and be sure to share your thinking.
