Cabri Express Primary vs SineField Waves

Features of Cabri Express Primary include a super easy primary calculator, geometry instruments, 2D & 3D shapes plus a dynamic geometry environment. App wrapped in an intuitive app that kids love to use. The primary version distinguishes itself from the secondary version in the look and in the calculator: the division is arithmetic (per default) and decimal numbers, fractions, roots and trigonometric functions are not made extra visible. These adjustments are the results of reviews with math education experts and with ministries of education. With its friendly interface, Cabri Express allows students to visualize and manipulate abstract mathematical concepts. The app is a laboratory in which they explore, model, and investigate without any limits. Cabri is free, it is the reference software for dynamic mathematics. It has been used for more than 25 years by millions of teachers and students around the world. Good maths for students and power & ease for teachers, to teach math not the software.
