Mentor Text-Linky

Happy Monday to you all!  I am joining up with the Collaboration Cuties for their Math Mentor Text Linky!  If you haven't checked it out, PLEASE DO!  I have gotten tons of ideas!  I got THIS idea from one of my brilliant inductees who did an activity that used the Marilyn Burns text The Greedy Triangle.    So, I had to test it out myself!   A dissatisfied triangle ventures out to become different shapes by adding a side and vertex each time.  The text shows the different places we might see such shape, like a pentagon on the soccer ball.  As the Greedy Triangle transformed shapes, I had my students add a side (pretzel) and a vertex (marshmallow) to create the new shape, and then record that information on THIS WORKSHEET.  They loved it!  They were amazed at how easily the new shapes were made.  They also enjoyed eating the snack afterwards!  See pics below! 

Here's what you need + the Text.
Have kids create the shapes by adding a side and vertex at a time.  Record the number of each for the shape.   

As a challenge, I asked them to make 3D shapes!

Voila!  Great activity, the kids were engaged the entire time!!  You can get the worksheet I used by downloading HERE.  If you would like to link up, head on over to the Collaboration Cuties! 


  1. I love this book! I haven't used it with marshmallows and pretzel sticks! That is a cute idea! I love that you had them switch to 3-D shapes! Very fun!

    Thank you for linking up!

    1. Thank you for the opportunity! I have so many new book ideas for next year now!

  2. I have never read this book. I'll have to check it out.
    I'm sure your kids loved making all of those shapes.
    Thanks so much for sharing. I'm a new follower.
