We learned about solid shapes.
We learned about flat shapes.
We described and named shapes.
This shape has 3 straight sides and 3 corners.
So, it is a triangle.
These shapes have 4 straight sides and 4 square corners.
So, they are all rectangles.
These shapes all have 4 straight sides that are the same length and 4 square corners.
So, they are all squares.
We built larger shapes from smaller shapes.
