Investigation Area of Geometric Shapes
Fourth graders use triangle paper to design patterns using geometric figures and find the areas of those figures by counting units. Students are assessed by determining which figure has the greatest area and explaining their reasoning.
Curated OER
Classifying Geometric Figures
Fourth graders recognize and classify geometric figures. In this geometry instructional activity, 4th graders read the books Shape Up and The Greedy Triangle and prepare a short report on the shapes mentioned in the text. Students...
