Curated OER
What Does It Take?
First graders study the attributes of circles, squares, triangles and rectangles. They sort shapes that are the same and those that are different into groups.
Curated OER
Rhombi
Learners examine the rhombi or diamond shape and compare it to the square. Students are challenged to create as many flat rhombus shapes as possible and develop a definition for the rhombus shape in 20 minutes while working in teams of...
