Eggsactly How Many?
Teaching Children Mathematics, v22 n9 p 526-528 May 2016
This investigation presents students with the challenge of determining the total number of eggs in a photograph of a stack of egg trays. The perspective of the photograph does not allow students to count all the individual eggs in the top tray but does allow them to see the number of eggs in one row and one column of the top tray. During this investigation, students have the opportunity to explore the structure of an array and how it can be used as a model for multiplication.
