After receiving some wonderful feedback from last week’s Polygon’s with The Greedy Triangle, I decided to go ahead and create a few more Math activities that correspond with this book!

Thumbs Up

At this point, you may or may not have already read The Greedy Triangle to your children.  If you have great-if you haven’t now you will!!  Prior to this activity, I recommend reviewing the different types of polygons listed in Polygon’s with The Greedy Triangle.  Afterwards, explain to your child that you will now read The Greedy Triangle to them.  Each time that they hear the name of ANY of the polygons reviewed, they are to put one thumb up into the air. (Model this for your kiddos so that they are 100% sure of your expectations!)  This is an excellent way to integrate your Read Aloud and practice Math vocabulary at the same time!

Depending on the age of your children, you may want to let them take turns reading out loud and having their siblings continue with ‘Thumbs Up” when they hear any names of Polygons!

Polygon Search

You will need:

  • Old magazines/newspapers
  • Scissors
  • Glue
  • Construction paper

After reading The Greedy Triangle, immerse your children with a variety of old magazines/newspapers and have them search for polygons within the photos.  When they find their polygons, help them cut and glue onto their construction paper.  When the glue has dried, have your child label each photograph/picture with the appropriate polygon name. Challenge: Find one photo/picture of each polygon.  If one cannot be found, one can be drawn!

When the Polygon Search is complete, hang it up in your child’s I.L.S. to use for future review.

The Greedy (Pentagon, Heptagon)

Ask your child this question, “If you could re-write this book using a different polygon, which one would you choose and why?”

Further promote this creative thinking by asking probing questions:

  1. How would this polygon react in _____situation?
  2. Why would you/wouldn’t you keep the same ending?

Now, get the paper and pencils ready!!!  Get your child excited about writing their very own The Greedy _______ Book!!  This is their opportunity to let their writing juices flow!

Extension: Take this activity one step further by promoting computer usage.  Your child will benefit from typing on the computer-they will have an opportunity to practice real-world skills, reading and writing.  When finished, print and post for all to enjoy!

Happy Learning!
