Students will compare and sort a variety of regular and irregular two-dimensional and three-dimensional figures based on their similarities, differences, and positions, regardless of their orientation or size. They will also combine two-dimensional figures to form a given composite figure by using a variety of materials and pictures. In addition, students will find real-world objects that can be modeled with a given two-dimensional or three-dimensional figure.

B.E.S.T. Benchmarks:

  • MA.K.NSO.2.1 Recite the number names of 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.1.2 Compare two-dimensional figures based on their similarities, differences, and positions. Sort two-dimensional figures based on their similarities and differences. Figures are limited to circles, triangles, rectangles, and squares. 
  • MA.K.GR.1.3 Compare three-dimensional figures based on their similarities, differences, and positions. Sort three-dimensional figures based on their similarities and differences. Figures are limited to 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. 
  • MA.K.GR.1.5 Combine two-dimensional figures to form a given composite figure. Figures used to form a composite shape are limited to triangles, rectangles, and squares. 

Key Concepts:

  • Build fluency when counting to 100 by Ones and Tens
  • Sort and compare 2D and 3D shapes
  • Combine 2D shapes and find shapes in the real world
