This is also very helpful as an adult who never received any formal education and studying on my own.
Through the scripted examples you can see the progression from all vs some. To use an example to from the lesson: "All triangles are _____________, but only some triangles are _______________". Students are now given the power to solidify a definition for what each shapes criteria is. This application and exploration of identifying the criteria through guidance of the teacher helps students hone in on their skills of categorizing and identify which is helpful in a myriad of life situations.
This is a great lesson to teach in a first grade classroom. I like how there are many different shapes with connections and many other examples of what are not shapes. Something I would do to add to this assignment; I would give the students wooden sticks (popsicle sticks) or clay to make the shapes on their desks to apply what they have just learned.
