Alex: Ye Ole Angles and More
Students will explore shapes and their attributes through a variety of resources including web sites, story books and manipulatives. Students will create a presentation of a shape adventure.
Texas Instruments
Texas Instruments: Copying an Angle
Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

Alex: Geometric Quilts
Young scholars will use a square to investigate other polygonal shapes that can be formed. Students will work with these polygons to make designs that will later constitute cooperatively designed quilts. The quilts will be made by...

Texas Instruments: Exploring Area
In this activity, students learn to calculate the area of geometric shapes. They solve real world problems involving area.
Texas Instruments
Texas Instruments: Coordinate Plane
In this activity, students use the pen feature of the calculator to draw geometric shapes in a coordinate plane.
Texas Instruments
Texas Instruments: Give Me a Hand or Leaf Me Alone
In this activity, students' find the surface area of geometric shapes cut from card paper and relate it to its mass. They use this data to find the surface area of irregularly shaped objects.

Alex: What's in a Box?
The class has been contracted to work for a box factory. They are to make cube shaped jewelry boxes. Students determine how many different nets are possible and then analyze the resulting cubes. This real-world situation helps to develop...

Nctm: Illuminations: Volume of a Cube
"The volume of a cube can be developed by considering unit cubes, a single row (longs) of unit cubes or a single layer (flats) of cubes using this applet." This easy software makes it possible to easily construct a cube and take it...

Alex: Creating a Reflection
In this lesson, the students will create geometric reflections. This is a hands on activity where the student will be able to conceptualize how geometric shapes are reflected across the x and y axis of a coordinate graph. This lesson...
Texas Instruments
Texas Instruments: What Goes Around Comes Around but Can You Measure It?
In this activity, students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.
