About the Math

  Skills and concepts below are learning goals for this standard.

  • Identify shapes regardless of their orientation or overall size   (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres)
  • Identify shapes correctly even when their size and orientation is unusual or different.

At this level of understanding, students need to recognize shapes and begin to notice their properties. Recognizing that some shapes have three sides, four sides, no sides is an important observation. Young children need experiences with recognizing two- and three-dimensional shapes. Most materials that teach children about shapes introduce some (triangles, rectangles, and squares) in rigid ways that wind up being exemplars. Shapes should be presented in different variants and orientations. For instance, triangles should be more than equilateral and not presented with the vertex at the top. Likewise, rectangles should be introduced in a variety of ways, showing varying orientation and length of sides. As all rectangles have four straight sides and four square corners, children should be taught that a square is a special type of rectangle. Squares have four straight sides of equal lengths and square corners.

 

Progression of Standard within Kindergarten

This progression informs how to develop the standard within the grade level. This progression is provided by HCPSS Elementary Mathematics.

Progression Throughout Year
Quarter 1 Quarter 2 Quarter 3 Quarter 4
  • Identify shapes regardless of their orientation or overall size   (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres)
  • Identify shapes correctly even when their size and orientation is unusual or different.
  • Describe two-dimensional shapes (circles, triangles, rectangles, and squares) by the number of sides and corners.
  • Describe why square is a special kind of rectangle.
