## Reflection: Developing a Conceptual Understanding Quick Flashes With Shapes - Section 5: Extra Practice

During this geometry unit, I want to continue the algebra momentum that I gained in the first few units.  Today, I included a problem titled How Many Rocks?  I wanted the students to continue to practice the story problem routine that had been created and to see which addition strategy each child was using when combining numbers.

I have included one piece of work (titled Emma) that can be found in the section resource.  This child is using the counting on strategy, but she doesn't know how to explain or illustrate her thinking.  In this case she has drawn out 8 hops and then 3 more and stated that she counted on from 8.  I called her over and we talked about her approach.  I modeled how to illustrate her counting on strategy (see the purple pen marks on the paper).

###### Three Dimensional Shapes
Big Idea: Put on your 3D glasses, sit back and enjoy the show! In this lesson, children will look at, touch, and arrange shapes, and discover that though the positions of shapes may change, their attributes do not change.

###### Prove it!
1st Grade Math » Shapes and Blocks
Big Idea: This is a great introduction to geometry in first grade or could be used as a Kinder lesson! Students use attributes to "prove" that they have a given shape.
