Kindergarten students need be able to name basic shapes and use position words.   Students need to understand what a 2d/3d shape is and be able to analyze describe each shape using appropriate mathematical terms.  Students will compare/contrast 2d/3d shapes and build models.  We had an awesome time creating 2d and 3d shapes out of toothpicks and marshmallows!  The Kinders did an amazing job and were able to describe their shapes using mathematical terms.

We used pattern blocks to show how you can put shapes together to make new shapes.  We learned that 6 triangles can join together to make a hexagon!   Two triangles make a rhombus and three rhombuses make a hexagon.  I was so impressed with their mathematical thinking 🙂

  • CCSS.Math.Content.K.G.A.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
  • CCSS.Math.Content.K.G.A.2 Correctly name shapes (regardless of their orientations or overall size.)

  • CCSS.Math.Content.K.G.A.3 Identify shapes as two-dimensional (“flat”) or three-dimensional (“solid”).

  • CCSS.Math.Content.K.G.B.4 Analyze and compare 2d and 3d shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).

  • CCSS.Math.Content.K.G.B.5 Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

  • CCSS.Math.Content.K.G.B.6 Compose simple shapes to form larger shapes. For example, “Can you join these two triangles to make a rectangle?”
