Math Students “Show What They Know”by doing an assessment on Topic 12 Congruence and Symmetry Envision Math - 3rd Grade - Topic 12-9 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Envision Math - 3rd Grade - Topic 12-6 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Mathematicians use objects to solve problems. Congruent Shapes Definition Two figures or objects are said to be congruent if one of them is a mirror image of the other or if both of them have the same shape and size. Envision Math - 3rd Grade - Topic 12=5 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Students use congruent shapes to build shapes that have symmetry. Envision Math - 3rd Grade - Topic 12-4 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Students create shapes with one or more lines of symmetry. Envision Math - 3rd Grade - Topic 12=3 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Envision Math - 3rd Grade - Topic 12=2 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry.ģrd Graders identify lines of symmetry in symmetric shapes. If they are similar, they should run to the right side. If they are congruent, students should run to the left side. Now take the whole class to big open space, such as outside or the gym. Students solve problems by first solving a simpler problem. Give students (or pair of students) the choice of drawing pairs of similar, congruent, or neither similar nor congruent shapes. Envision Math - 3rd Grade - Topic 12=1 MA.3.G.3.3 Build, draw, and analyze two-dimensional shapes from several orientations in order to examine and apply congruence and symmetry. Congruent shapes are the same size and same shape.
