Item description

One of the most iconic geometry and sensorial materials in a Montessori classroom is the Geometry Cabinet.

This material is suitable for any classroom, homeschool, or educational environment – you do not have to be a Montessori teacher. Save yourself HOURS of work.

This resource includes:

  • Geometry cabinet material analysis
  • 10 presentations that include all of the geometry insets
  • Detailed step-by-step presentation instructions
  • Illustrations and photographs
  • Etymology of the shape names
  • With each presentation is given the purpose, direct aim(s), indirect aim(s), control of error, and points of consciousness

Please note that the preview only shows a few pages of the manual – I have included the Table of Contents in the preview. Please reach out if there are any questions. 

This resource is the 2nd unit of the Montessori Geometry Curriculum for 6-9 year olds.



Classify two-dimensional figures in a hierarchy based on properties.

Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).

Correctly name shapes regardless of their orientations or overall size.

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.

*Homeschoolers and regular classroom teachers can use these lessons with printable insets if a geometry cabinet is not available. These printable insets are not included in this resource, but are readily available online. Please message me if you have any questions; I am happy to help.
