The Greedy Triangle

I love the book, The Greedy Triangle, by Marilyn Burns to help young children with geometry.  Here is a great activity from the blog Fun in First Grade that pairs writing and math.

Geometry

Here is a free resource from Math Learning Center you might want to check out. It is a free resource guide for using geometric blocks. My friend Kim also came up with the idea of going on a shape scavenger hunt with the iPod Touches. The children will go around school and take pictures of certain shapes. I will post more about this once we have figured out all the details.

Math Flashcards

Here is a great resource for all different types of Flashcards from the site Have Fun Teaching.

Teaching Math Videos

This link has free videos about teaching math from the Annenberg Foundation website.

Online Games

The blog First Grade in the Desert recently posted a link to the Investigations online math game site.  There you will find games for counting/numbers, addition/subtraction, geometry, data, and patterns.

Geometry-Pondering Polygons and Virtual Geoboard

Here is a virtual geoboard to use on your computer.  The next resource is by Laura Candler and it is Pondering Polygons.  I like this page because it has the students pair math with writing.  They are given a shape and asked a question about the shape.  The student has to answer yes or no and give a reason for the answer.

Geometry-Polygon Song

I love this fun song about polygons.  It takes a boring square and changes him into all different shapes.  This is great to review vocabulary, but it will stick in your brain!

Geometry Lesson On Polygons and Symmetry

This is an interesting site. I like the flip book that the chilren make.  They choose shapes and then write yes or no on the inside if it is a polygon or not.  This is from the blog love2learn2day.

Interesting activity using Legos to help children learn about symmetry.

Cool Geometry Site

Check this site out!  It is called Math Cats. One of its features is something called Math Cats' Crafts.  If you are looking for ways to get your kids excited about geometry, you should check it out!
