In Second Grade

  • Students in second grade classified and sorted three-dimensional solids and polygons as well as created two-dimensional shapes and three-dimensional shapes. Students also decomposed two-dimensional shapes.

In Third Grade

  • In third grade, students will use attributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as example of quadrilaterals, and classify and sort two-and three-dimensional figures based on their attributes. These figures include cones, cylinders, spheres, triangle prisms, rectangular prisms, and cubes.
    Students will also decompose composite figures into non-overlapping rectangles to determine the area of the original figure, decompose two congruent two-dimensional figures into parts with equal areas, and determine the area of rectangles using the length of the sides.

In Fourth Grade

  • Fourth grade students will identify points, lines, line segments, rays, angles, parallel lines, perpendicular lines, one of more lines of symmetry, and solve problems involving perimeter and area.
    Students will also classify two-dimensional figures based on the presence or absence of parallel lines, perpendicular lines, or angles of a specified size, identify rights, acute, and obtuse triangles based on their knowledge of right angles, and use a protractor to measure angles.
