Uncovering the Hidden Math in Nature
Presented by Cyndi Blankenship & Donna Kouri
Purpose
Using images from nature, your students will locate, identify, label, and create a presentation
showing geometric objects.
• Inexpensive
• Immediate and unlimited images
• Easily duplicated and stored
• Digital cameras embedded in everything
Digital
Why ?
Create
Evaluate
Analyze
Apply
Understand
Remember
• Photographs “freeze” the image
• Allow students to focus
• Intent focus invites inquiry
• Inquiry demands context
• Context is the scaffolding of knowledge
Inquiry-Based
To begin with inquiry based learning, we need to start with a base of what we know.
We know that we can identify shapes by their characteristics and properties. We know a shape
with three sides is a triangle.
Take at least 10 pictures in nature that represent geometric shapes.
Following are some suggestions:
Are You Ready?
This is an example of a close-up
Geometric shapes are shown nicely in this photo.
This could be an example of a photo that is fun!
Take at least 10 pictures in nature

What lies within this photograph?
A line is a collection of points going on and on infinitely in both directions. It has no endpoints.
Intersecting Lines
What type of line has one end point in common?

Then, begin to view one photo at a time to look for geometric figures
If at first you do NOT see something…skip it and come back later!

Benefits of Digital Photography in the Classroom
• Promotes active engagement
• Student-directed instruction
• Instant feedback for students and teachers
• Connects the classroom with real world
• Promotes collaboration between students: provides a bank of photos to be used in the future
What do you see here? Everyone might see something differently.
