Digital Cameras 

Digital
cameras are excellent tools for enhancing the math classroom.
They can also assist with applications under the current math reform
movement, moving away from isolated problems in a drillandpractice
format to authentic experiences and problem solving. Digital
images can be used to help demonstrate accomplishment of standards
such as National Council for Teachers of Mathematics (NCTM) standards
for Algebra, Geometry and Measurement. For example, you could
apply standards by having images that allow students to measure and
compare sides, shape and angles by using images as models. Digital

Additionally, digital cameras can be used for math applications covering topics such as direct and indirect measurement, manmade and natural geometry, money and counting, measurement and scale, and the congruency and similarity. 

Use your digital
camera to demonstrate perspective by showing objects situated at
different distances, or set up a discrepant event as displayed in
this image where a known larger object appears smaller than a
comparative known smaller object. 

Scale and
measurements: Use your camera to capture objects at the same
distance to calculate the height of an unknown object or to
calculate the volume of an object. Geometric shapes are shown here
with the lighthouses as cylinder and conic sections. 

You can enhance
through photomanipulation existing geometric shapes by adding
highlights to the images to outline the shapes. In this image,
a picture of the front of a building was enhanced to show the basic
shapes on the building, including the triangle, rectangle,
semicircle, square, and others. 

Show objects that
demonstrate structural strength, tension, and construction using
geometry. In these photos a bridge which uses the basic
structural shape of triangles with the tension wires in the shape of
the bridge. 

Demonstrate math
manipulatives. Using a camera with live video output, students can
participate in problemsolving while watching the steps on a large
screen TV. The images can then be included in assessment
tools, with the advantage of being more authentic. 

Show objects or shapes that demonstrate understanding of congruency and similarity. 

Take pictures that show geometric transformations: Flips, Slide and Turns. Use the images to create a multimedia presentation.
