The Micro and Macro World Around Us
Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Pythagorean Theorem by Graphic Manipulation
There are many different ways to show a proof of the Pythagorean Theorem. Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Perimeters, Patterns, and Conjectures
Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...
Curated OER
Triangle Explorer
Students calculate the area of triangles using a variety of materials including computer applets.
Curated OER
Geometry in Tessellations
Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Tick Around the Clock
Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
