Ship Shape
Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.
Curated OER
Construct Figures to Find Specific Volume
Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...
