Name Number
You will be designing and building a gingerbread house, using several geometric shapes and symmetry that we have learned this year. Your grade will be based on your identification and definitions of the different geometry concepts on your own Geo-
Bread House.
In order to make this project a success, you will need some supplies. Please have all supplies to school by Monday, December 19 th . Each of you will need to bring in an
empty box of tissues or another small cardboard box to use as a base for your house.
You will also need a box of plain graham crackers and a container of ready-to-spread
white frosting. Also, each of you will bring in a candy to share with the whole class that will be used to decorate the houses. Please contribute to our gingerbread house supplies by bringing in .
You will have some time in class to plan your Geo-Bread House design so that you can be sure to include all of the required geometric elements (on the back of this page).
