The Van Hiele levels are a theory of geometric thought development proposed by Dina van Hiele-Geldof and Pierre van Hiele in the 1950s. Clements and Batista (1994) further expanded on this theory by classifying the levels into five distinct stages.
Levels 1 to 3 of the Van Hiele levels are characterized by different levels of geometric understanding and reasoning.
Level 1: Visualization
At this level, students are able to recognize and identify basic geometric shapes and figures based on their appearance. They can visually distinguish between shapes such as circles, squares, triangles, and rectangles. However, their understanding is limited to the visual appearance of the shapes and they may struggle to describe or analyze their properties.
Example: A student at level 1 may be able to identify a square as a shape with four equal sides and four right angles based on its appearance, but may not be able to explain why these properties make it a square.
Level 2: Analysis
At this level, students begin to understand the properties and relationships between geometric shapes. They can compare and contrast different shapes based on their attributes and recognize patterns and similarities between shapes. Students at this level can also start to classify shapes based on their properties.
Example: A student at level 2 may be able to identify that a rectangle has four right angles and opposite sides that are equal in length. They can also compare a rectangle to a square and recognize that both shapes have four sides, but a square has all sides equal in length while a rectangle does not.
Level 3: Informal Deduction
At this level, students are able to make logical deductions and draw conclusions based on their understanding of geometric properties. They can use deductive reasoning to explain why certain properties hold true for specific shapes and can apply their knowledge to solve geometric problems.
Example: A student at level 3 may be able to prove that the sum of the interior angles of a triangle is always 180 degrees by drawing and manipulating different types of triangles. They can also use this knowledge to solve problems involving angles in triangles.
In conclusion, levels 1 to 3 of the Van Hiele levels represent different stages of geometric understanding and reasoning, with students progressing from basic visual recognition of shapes to more advanced analysis and deduction of geometric properties.

Van Hiele Levels 1-3
Level 1: Visualization
- Description: Students focus on the objects themselves and can recognize and name shapes.
- Examples:
- Pointing out a triangle and saying "This is a triangle."
- Sorting shapes based on their appearance (e.g., triangles vs. circles)
- Describing the shape of a real-world object (e.g., "This is a square table.")
Level 2: Analysis
- Description: Students focus on the properties of shapes, such as angles, sides, and vertices. They can identify and describe these properties, but may not yet understand the relationships between them.
- Examples:
- Counting the sides and vertices of a shape
- Identifying the angles in a triangle (e.g., right angles, acute angles)
- Describing the symmetry of a shape (e.g., line symmetry, rotational symmetry)
Level 3: Abstraction
- Description: Students begin to understand the relationships between the properties of shapes and can classify shapes based on these relationships. They can define shapes in terms of their properties.
- Examples:
- Understanding that a square is a rectangle with four equal sides
- Identifying that all parallelograms have opposite sides parallel
- Defining a triangle as a polygon with three sides
- Using Venn diagrams to classify shapes based on their properties (e.g., as polygons or non-polygons)
