Diagnostic Geometry Assessment
Introduction Linearity illusion, a tendency to see any relation between two quantities as a proportional or linear one, is a phenomenon in mathematics education, especially among students in lower education level.
Why teach Geometry? There are a number of reasons why geometry holds an important place in the curriculum.
Why teach Geometry? There are a number of reasons why geometry holds an important place in the curriculum. We list some of these below.
The following examples of student work illustrate achievement at the mathematics standards for years 5, 6, and 7.

Misunderstanding of ‘realistic’ Despite this clear statement about horizontal and vertical mathematization, RME became known as ‘real-world mathematics education’. This was especially true outside the Netherlands, but the same interpretation can also be found within the Netherlands.
Realistic Math Makes Sense for Students
Geometry is a branch of mathematics that is concerned with the properties of configurations of geometric objects - points , (straight) lines , and circles being the most basic of these. Although the word geometry derives from the Greek geo (earth) and metron (measure) [ Words ], which points to its practical roots, Plato already knew to differentiate between the art of mensuration which is used in building and philosophical geometry [ Philebus (57)]. Earlier in the dialogue [ Philebus (51)], Socrates mentions the matter of beauty:
EggMath: Welcome to EggMath This is the EggMath version 1.5, a collection of web modules (including many interactive applets) covering different topics in mathematics related to eggs; it is intended for use in K-12 classrooms, as in the Chickscope project at the Beckman Institute. The current modules deal with:
Visualization is an important part of geometrical thinking. It's the skill you use when you pretend to be somewhere else and imagine how that place looks, or when you fancy how a situation would look if things were just a little bit different. But visualization is especially problematic in three dimensions—perhaps because math curricula do not emphasize three-dimensional geometry.
In five interactive geometry investigations, students explore geometric solids and their properties. Throughout the unit, students analyze characteristics and properties of three-dimensional geometric shapes and develop mathematical arguments about geometric relationships. Students construct various geometric solids using an interactive tool, and explore and create nets for various geometric solids.
