K.GM.1.4 Use smaller shapes to form a larger shape when there is an outline to follow.


In a Nutshell

Students should be able to take smaller shapes and build larger shapes from them.  This is very naturally accomplished with pattern blocks during exploratory time. For example, students can make a triangle out of pattern blocks in multiple ways.  After students are allowed time to explore with pattern blocks on their own, give them outlines of larger shapes that they can fill in. This can also be done by cutting up paper shapes (ex. cut a square into triangles) and have students put them back together.

Student Actions

Teacher Actions

  • Build conceptual understanding by exploring and testing different combinations of shapes to fill a given outline.

  • Communicate mathematically by discussing and sharing the shapes used to fill a given outline. 

  • Develop problem solving strategies through exploration  by turning, flipping, rotating, etc. shapes.

  • Build procedural fluency as students use shapes to fill in a variety of outlines.

  • Develop a productive mathematical disposition by playing with puzzles. 

  • Supporting productive struggle by asking questions to help guide students through any problems they encounter.

  • Facilitating meaningful discourse by encouraging students to find multiple ways to make each shape.

 

 


Key Understandings

Misconceptions

  • Properties of common shapes.

  • Smaller parts make a larger whole.
  • Full sides of shapes need to be touching. 

  • Shapes must be the same size to complete the outline.

  • Using shapes that do not fit within the outline given.
