## Reflection: Connection to Prior Knowledge Grandma's Cookie Production Company - Section 1: Warm-Up

I chose multiplication as my warm up for this division lesson because one of my overarching objectives in teaching division is to make a connection to multiplication. While we, as adults, readily see the connection between multiplication and division, younger children – my third grade students for example – usually don’t. Their initial development of division understanding generally starts with seeing it as “separate” from other operations.

In using the pictures of arrays for a multiplication game, the students are actually describing the division as well when they are looking at the groups the whole is made up of.  I think this is a perfect transition game to use when moving from multiplication to its relationship with division.
