There are many misconceptions about how the animal kingdom is classified. We like to begin the unit by brainstorming what the kids already know. This seems like a good way to organize what they already know in order to eventually come up with a visual representation of the classification of the animal kingdom.

I must have classification in my head today. In math, students know what the 2D shapes are but have a hard time articulating their similarities and differences. For example, what do rhombus and squares have in common and how are they different. I think this format may help students in two ways: to not feel pressured to answer right away and to be able to look at other students' posts in order to get rid of common misconceptions.
