The following geometry games are suitable for elementary and middle school students.

2D Shapes (Jeopardy Game)

Classify angles as acute, right, obtuse, or straight when you play this interactive Tic Tac Toe game against the computer. Classifying Triangles Game

In this interactive game, kids will practice classifying triangles as as acute, right, or obtuse by dragging and dropping different images in the correct basket in less than two minutes. 2D Shapes Game (Concentration)
In this game students click on two cards to match the figure of a two-dimensional shape with its name. If there is a match, the problems remain on the page; if not, the cards are turned over.

Classify geometrical figures as 2-dimensional or 3-dimensional by playing this fun and interactive geometry game. Polygon or Not?

Do you know if a given geometric figure is a polygon or not? Play this fun game to demonstrate your skills! How many points can you score in one and a half minutes? 3D Shapes Game (Concentration)
Have fun matching pictures of three-dimensional shapes with the correct words. If there is a match, the problems remain on the page; if not, the cards are turned over. Types of Polygons

In this game you have to quickly name different types of polygons based on given clues. For each question you will have only 30 seconds to write your answer. Angles Jeopardy Game is a fun way to assess your knowledge about measuring and classifying angles. The game has a single-player mode and a multi-player feature. 3d Shapes Game

The following common geometry formulas are very useful when solving problems about two-dimensional figures. In the table below “b” stands for base, “h” means height, “L” stands for length, “w” represents the width, “r” is the radius of a circle, and “d” represents the diameter. When solving problems about area, perimeter, or circumference, first you need to identify the important elements in your figure. Then, find the formula that applies to your problem, and simply replace the letters with the correct values. Make the necessary computations, and don’t forget to add the unit at the end.

You can also find the area of a figure by counting the number of square units inside it (if it shows in the picture). When finding the area of a triangle (or parallelogram), you can use the length of any side as the base. The height is always perpendicular to the base.

#### Geometry Nets  http://www.kidzone.ws/math/geometry/nets/

A "Geometry Net" is a flattened  out three dimensional solid (a three dimensional shape) -- like a cube, a prism or a pyramid.  When you cut out the "net", fold it and glue it together you can see what the three dimensional shape looks like.

A three dimensional shape is called three dimensional (or 3D) because it has three dimensions:  length, width and height.

The two most common measurements we need for a three dimensional shape is:

• volume:  for example, how much water it would hold
• surface area:  for example, how much area you would have to paint to cover the entire outside of the shape

Creating paper models like these geometry nets allows children to explore the more familiar 2 dimensional shapes that go into making a three dimensional one.

I think it's particularly fun to do these during Christmas -- you can hang the three dimensional shapes on the Christmas tree.

By Shape - Platonic Solids (all the sides are identical):

Geometry Net Cubes-- all the sides are squares

Geometry Net Tetrahedrons-- all the sides are triangles

By Shape - Prisms (a 3D shape where if you sliced it like a loaf of bread, each slice would look identical):

Geometry Net Rectangular Prisms-- all the slices are rectangles

Geometry Net Square Prisms-- all the slices are squares
