This Smart Notebook Lesson is a fun culminating activity on unit rate. Using the 12 Days of Christmas song, students will go through 12 different presents they will buy for you, their teacher! ;) Students must calculate the unit rate of each day's gifts, and write it using the proper notation. This lesson can be completed using the attached word document with colored pictures, or you can be even more creative and have students cut out each day's gifts to create a foldable book.
