Curated OER
"Polly"gon Pockets
Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...
Curated OER
Fun With Transformations
Demonstrate and discuss the three types of transformations: rotation, reflection, and translation. Participate in a game which helps to reinforce and practice what they learned. Groups work collaboratively to complete the game.
Curated OER

This lesson plan reviews transformations in the coordinate plane while mimicking real-world planning skills. It gives an assessment and ideas for remediation, extention as well as ways to manage behavior problems and reluctant learners.
Texas Instruments
Texas Instruments: Dimensional Figures
Students use the Explorer Draw application to draw two-dimensional figures. They understand how to write commands to draw squares and hexagons. They also calculate the perimeter of the figures drawn. [Requires Adobe Reader.]

This applet allows you to examine various two-dimensional figures to determine which ones can be folded into a cube.
University of Regina (Canada)
University of Regina: Math Central: Lesson: Mr. Z's 5 Minute Game of Geometric Pandemonium
Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...
