Happy Hierarchies :)


Hey kids!

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.

Woooaaahhh...Woooaaahhh... Quad-ri-later-als... Quad-ri-later-als...

During our last class we learned some important vocabulary words we could use to describe a polygon:

Plane, parallelogram, congruent, quadrilateral
to name a few.

Below you will find  our lovely Polygon Brainstorm.

As with all images on this site, click on the picture for a larger view.

Now, we will take the info we already have in our brains (and notebooks), and learn to classify polygons. Here are a few images to help you get started. 

Our 5.G.3 notebook pages include vocabulary words and three handy charts. You may need several pages to fit all of the information. Check your k-mail for printable pages!


  1. 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. 

Here is the example we used in our math notebooks. 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. I enlarged the chart on this page, so you can use it to complete your math notebook page, if needed.

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.

Now, on to fractions!
