Pick-a-brick wall at the Lego store

There are walls at the Lego stores that are filled with individual Lego parts.  You can fill a bucket and pick out exactly what you need. Use this activity to get your students conferring with each other, making guesses, and explaining their reasoning.  Students try to determine the number of Lego bins on this giant wall.  Students think about arrays and multiplication as they consider a reasonable quantity of Lego bins in this three-act task. 

For Adventurer members we have a teaching suggestion and solution document.

Special thanks to math teacher Megan Schmidt for snapping and sharing the pictures for this activity!
