Super Sort
Students sort objects based on one characteristic. They define the term "attribute" and give examples of attributes of objects. Students explain their reasoning for sorting objects into groups.
Curated OER
Drawing Lines of Symmetry
Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.
