Curated OER
The Gum Drop
Students find the area of three figure by the traditional formulaic methods. Then they count the number of grid squares to double check. They show an intuitive sense of Pick's Algorithm by counting every two boundary squares as one unit....

Finding the Area of Shapes
In this area of shapes unit, upper graders participate in hands-on problem solving activities to find the formulas for the area of a parallelogram, a triangle, and a trapezoid. They manipulate the geoboard to explore relationships among...
Curated OER
Fill 'Er Up
Students identify how many smaller units can be found in a later unit. In this geometry lesson, students calculate the volume and the transfer amount to a smaller unit. They solve real life problems using the formula for volume.
