To restart our thinking about area, we used a routine called, 'information invasion' which is when we fill a space with our knowledge about a certain topic, in this case, "area". After students wrote their thoughts, we put a spotlight on each one to generate a class discussion. The knowledge that was shared, helped bring us to an understanding of area. For example, area is when you find the total amount of square units, and not just the sides. We found out that that is called "perimeter". Due to this thinking routine, we practiced looking for area by multiplying two numbers representing the sides of the object.
