Are you trying to integrate subjects with Common Core?
This is the perfect way to integrate math, reading and writing (and many times-social studies)!
One of my guided math groups is called "math literacy". I put a children's book, math literacy card and cute stationary in a bag. Students read the book (individually), that's based on a math standard, and respond to the prompt. This set is geared toward geometry standards. Included are 12 cards. I have also included a list of books you will need and their guided reading levels (ranging from J to S). I get many of my books from the public library or our school's media center.
The math literacy cards are based on the following books:
Sir Cumference and the Great Knight of Angleland
The Greedy Triangle
If You Were a Quadrilateral
Grandfather Tang’s Story
What’s Your Angle Pythagoras?
Let’s Fly a Kite
Sir Cumference and the First Round Table
A Cloak for the Dreamer
You will need to check out the books, print the cards on card stock and laminate for durability, put them in a bag and you're ready to go!
