2nd grade mathematicians are using new words in class lately to describe geometry related tools and 2-D and 3-D shapes. Terms like points, line segments, straight edges, polygons, and line symmetry, were introduced this week as students used straight edges to create line segments and polygons from given labeled points. They will also work to find line symmetry and move towards a study of 2-D and 3-D shapes. Students will soon begin to note 2-D and 3-D are all around them. Blocks, manipulatives and household items like cans and packaging offer examples of geometry right in their classrooms and homes. Students were also introduced to math station work to extend their geometry experiences after they complete mini-lesson independent work during math workshops times. Friday review sessions of our Optional Math Challenge extensions are going well as students are growing comfortable sharing the strategies they used to arrive at solutions for the weekly problem offered.
