Students will identify two-dimensional figures, including circles, triangles, rectangles, and squares, and they will recognize squares as special rectangles. They will use formal and informal geometric language to identify the attributes of two-dimensional figures. In addition, students will find real-world objects that can be modeled by a given two-dimensional figure. Students will begin identifying three-dimensional figures, including spheres, cubes, cones, and cylinders, in the real world. They will take notice of examples of these figures that they are exposed to in everyday life to determine how each of these types of figures have common attributes. They will use their knowledge of two-dimensional figures to identify the components of three-dimensional figures.

B.E.S.T. Benchmarks:

  • MA.K.NSO.2.1 Recite the number names of 40 100 by ones and by tens. Starting at a given number, count forward within 100 and backward within 20 
  • MA.K.GR.1.1 Identify two- and three-dimensional figures regardless of their size or orientation. Figures are limited to circles, triangles, rectangles, squares, spheres, cubes, cones, and cylinders. 
  • MA.K.GR.1.4 Find real-world objects that can be modeled by a given two- or three-dimensional figure. Figures are limited to circles, triangles, rectangles, squares, spheres, cubes, cones, and cylinders. 

Key Concepts:

  • Build fluency when counting to 40 by ones and tens 
  • Identify, Name, Describe, and Classify 2D Shapes   
  • Identify, Name, Describe, and Classify 3D Shapes
