Curated OER
Learn the Shapes
Students examine and identify the similarities and differences of two-dimensional shapes. They play an I-Spy shape game, participate in a classroom Shape Search, and create illustrations of shapes for a shape collage.
Curated OER
Echolocation Lab
Students explore echolocation of animals. They examine how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight. Through experimentation, they discover how sound waves...

ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Make Your Own Shape Puzzles
Students create their own shape puzzles. They practice putting puzzle pieces together so they fit correctly. They classify and sort the different shapes as they finish the puzzle.
Curated OER
I Walk the Line
Students walk, run, jump, and hop all over and around geometric shapes. They identify the shapes by running to and standing on the called out shape.
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
Curated OER
Exploring Shapes
Young scholars practice moving over shapes they have designed. They work on trying to travel around the shapes while practicing their jumping and landing patterns.
