Geometry! Common core -ified!

Geometry has always been one of the most fun units in first grade math.  We took this  unit  and Common-core-ified it up to make it more rigorous but we kept the fun!  

The standards that we worked with are 1.G.1 and 1.G.2:

1. Distinguish between defining attributes (e.g., triangles are closed and

three-sided) versus non-defining attributes (e.g., color, orientation,

overall size); build and draw shapes to possess defining attributes.

2. Compose two-dimensional shapes  or three-dimensional shapes

 to create a composite shape, and compose new shapes from

the composite shape.

We pulled out every kind of manipulative we had and came up with activities for them!   One of the kids favorites was building the shapes out of playdoh and tooth picks!  Here are some of the 2D shapes we built!

Tip: You have to have larger vertices made out of the playdoh or they will fall apart too easily and the kids get frustrated!
and...  don't buy 6000 toothpicks!  1 box of 1000 was way more than enough! 
(Learned that one the hard way!) #overachiever  

 And in Common core fashion, we wrote on a recording sheet to explain what we knew about our shapes! 
There is a LOT of writing in this unit! 
I made a point of explaining that the playdoh balls were called vertices or corners.  They picked u;p the terms pretty quickly! 
We did this a few days later using 3D shapes.
They also loved our "Shape Snack!"

The kids all brought in food "shapes" and we ate them as a snack!

and of course, writing to tell about it!  We had so much food we did this all week!  and... wrote about it every time!  By the end of the week, I was getting some GREAT! sentences! (I made them write a sentence before they could dig in!  #willbeengagedforfood)

The super cutest thing about it all?  They kept on talking about what shapes they were eating at lunch and snacks!

We watched "Spookly the Square Pumpkin"

this led us to a discussion about whether or not he was indeed a square! (lol this was not intended!)
We decided that they called him a square because his face was a square- but he was really a cube!  Nice segway into the faces on a 3D shape!  I love when the stars allign for these teachable moments! 

And we made Amy Lemons cute little Owl Craftivity!

We discussed the shapes it takes to make the owl.  This fit wonderfully into our Owl Unit we are working on!  I found this Red Ribbon Week display to put on our bulletin board! 

We finished up with daily building and tangrams taskcards to make our composite shapes!  It was a lot of fun Hands-on activities!  I could not be happier! 

All of these activities into my best selling unit.

I included every manipulative I could and wrote assessments to end each of the standards.  I also included a page of technology links and a sample lesson plan to explain how I used it!

Hope you have a great night!
