Yesterday we looked at different types of polygons and some ideas that you could use to help your students categorize shapes. I wanted to extend this idea a bit further and introduce Gribbles to you :-D.
Okay you may be wondering what Gribbles are, but I’m not going to tell you. That’s for you and your students to work out. Below is how you can use the idea of Gribbles to get your students to explore and classify shapes.
Here are some Gribbles
Here are some shapes which are not Gribbles
Which of these are Gribbles?
Here are some questions and other ideas that you can use to extend the concept further:
- In your own words, describe the features common to all Gribbles.
- Why are the members of the second group not Gribbles?
- Draw two Gribbles of your own.
- Draw your own set of Gribbles and non-Gribbles. See if a classmate can identify your Gribbles.
So what’s stopping you….get Gribbling 😉
