Gingerbread Cookie Arrays

In Math class today, we put our knowledge of multiplication to the test! We started learning about arrays yesterday, which are rows and columns of dots that help us to learn different multiplication facts. Today we were given a sheet of 24 gingerbread men pictures and this challenge: "Ms. Van Sickle has to bake 24 cookies. She wants to arrange them on a cookie sheet. What are the different ways that the cookies could be arranged on the sheet in rows and columns? Arrange your cookies in as many different ways that have equal columns or rows."


This student found that she could arrange them in a 2 x 12 formation.


This student is working on the 4 x 6 formation.


We were challenged through trial and error. Not every formation ended in equal amounts of rows and columns.
