TEKS Audience: First Grade. Behavior: Sort and classify shapes. Condition: Using attributes and informal geometric language. I believe this activity matches the TEKS because this anchor chart teaches students to look at shapes and their attributes.
A Place Called Kindergarten: math.love this as a center for sorting shapes! (Could also make shape mats all white or black so the children are only using the shape without the color cues after they master it with colors)
