This week 5th graders are continuing a study of polygons in math class. If you need a refresher as to what a quadrilateral is, check out this movie. I apologize in advance if it gets stuck in your head for, like, ever.
ˈhī(ə)rärkē/
noun
- a system or organization in which people or groups are ranked one above the other according to status or authority.
A hierarchy in geometry is very similar to the definition above. Except instead of talking about people (like military ranks), we are classifying shapes based on their properties. You start with a broad category at the top of the chart, like "Polygons." As you add branches, you split off to define specific properties of shapes.
In the chart below, "Quadrilaterals" is at the top of the hierarchy. As you branch off from that general term, you get more and more specific.
Here is another hierarchy chart I found online. I know how you like happy shapes, so you may want to add this chart to your math notebook. That's what I'm going to do! Click on the image for a printable version. Thanks Ms. BBZ!
Awwwww... Such a cute and happy polygon family!
Here are four fun and interesting math resources that have to do with this week's math concept.
