This is a lesson plan that will help educators teach Kindergarten students about 2D and 3D shapes, how to identify, sort them and design their own using marshmallows and toothpicks. Assessments and Rubrics are included to assess students on identifying, sorting, and designing 2D and 3D shapes.The image used in the Image Title was a screen shot taken from the Youtube Assessment that is linked to the lesson plan.

This hands-on activity helps students develop spatial sense and scaling concepts. Students use interlocking cubes to build first a chair and then a table of appropriate size for the chair. The student goes on to build two other sets of chairs and tables to make three different sizes in all. The Teachers' Notes page includes suggestions for implementation, discussion questions, and ideas for extension.
This activity asks students to recognize differences in shapes and sort them. They are given a set of 15 shape cards that they can sort by the criteria of color, size and shape. Ideas for implementation, extension and support are included along with a printable sheet of the cards.
Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.
