Shapes on the Geoboard
Create fun shapes on the Geoboard! Your young scholars will have a blast discovering new ways to form familiar and unfamiliar shapes using rubber bands. They choose a favorite shape and record it, then write about their shape. Use these...
Curated OER
Learning by Logic - Total Surface Area
Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.
Curated OER
Developing an Understanding for Square Roots
For this algebra worksheet, students discover properties of squares while making squares with a Geoboard. There are two charts to complete and 15 questions.
Curated OER
Geoboard Squares
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...
Curated OER
Ship Shape
Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.
