This package includes parent letter, supplies list, and copies of the recipe. I have done this activity several ways. If you have enough adults, set up several stations where small groups of students are making cookies at the same time. If you are the only adult, set this up as 1 rotation along with some other learning centers. It will take at least 30 minutes to complete the activity.
When you are ready to have students bag up the cookies to take home, make sure you have them figure out how to divide the cookies evenly. It is a great real life problem!
