Unit 10: Finalizing Understanding of Classifying 2-D Figures
Essential Questions
What can we learn about shapes by sorting them in different ways?
How do I know what name to call a shape?
Students will be able to…
Classify two-dimensional figures in a hierarchy of sets and subsets with graphic organizers.
Computational Fluency TEKS: 10 - 15 minutes every day
