Cabri II Plus is a software recognized by experts in pedagogy, specifically for its simplicity of
use and solid educational foundation.
Cabri: Software serving pedagogy
Tools for students: « from exploration to understanding »
With just a few clicks, students can:
Construct 2-D and 3-D figures, from the simplest to the most complex, by combining fundamental geometric objects such as points, angles, segments, circles, planes, solids and transformations.
Create expressions using fundamental algebraic concepts, such as numbers, variables and operations.
Connect geometry and algebra by measuring length, angles, area and volume and then attaching these numeric values directly to the figure to use them in calculations or in algebraic expressions.
Explore a figure's properties by manipulating its variable elements. Observe the effects of dynamic transformations like shrinking and enlarging. Make conjectures about algebraic and geometric properties, and then verify relationships among various parts of a figure.
Tools for teachers: « from lesson plans to assessment »
The teacher can:
Create activities that:
- facilitate the introduction and understanding of new concepts
- promote the discovery of theorems, instead of just showing them
- help model real-life situations.
Generate classroom resources by inserting text or pictures in a figure, modifying graphical elements, copying/pasting into other software and producing high-quality printouts.
Present activities to students, have them manipulate figures, observe and guide them. Using Cabri allows you to better assess individual student comprehension.
Expand online by integrating figures that can be manipulated on web pages or by incorporating Microsoft Office® documents.
Have students solve problems directly linked to the NCTM standards with possible interdisciplinary connections to physics, geography and the arts.
Focus on the features of Cabri II Plus
Building upon the features common to all Cabri products, Cabri II Plus adds:
Tools for new learning opportunities
Basic tools borrowed from traditional design tools: compass, T-square
Advanced tools:
- place and trace: display the paths of geometric figures when they are distorted.
- redefine objects: add or subtract constraints on the relationship between the objects in the figure.
Numeric and algebraic tools: coordinate points, equations of lines, graphical representations of functions and tables
Tools that can be personalized to meet each teacher's needs
Save the history of figures: simultaneously follow the work of several students by replaying each of their actions step-by-step.
Create your own tools in order to remake frequently used constructions in just a few clicks. Design « black box » tools whose functions are to be discovered by the students.
Modify the toolbar to fi t the level of the class or the planned activity.
Link between the calculator and computer
Import/export files between the teacher's computer and the students' graphing calculators, from Cabri II Plus to the free application Cabri Jr. (available on TI-83 Plus and TI-84 Plus calculators).
