Big Idea:First graders begin to learn about plane shapes in Kindergarten. This lesson will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.
Big Idea:How many vertices? How many sides? These are important attributes I want my First Graders to identify in plane shapes. This lesson will provide practice in noting these differences and similarities.
Big Idea:We have identified plane shapes in our classroom, learned shape attributes and vocabulary, and built 3D shapes from 2D plane shapes. I'm driving this unit home by having my students identify real-life 3D objects in our classroom.
