Mathematical Functions 3 FREE

An introduction to mathematical functions, suitable for Mathematics students from grade 8 onwards. This educational game uses 60 images to help students to recognize the graphs of the basic mathematical functions, y = x, sin(x), cos(x), tan(x), exp(x), log(x) and sinc(x) and their reciprocals, reflections and powers.

Students hear the name of a function and choose the matching graph. After six right in a row, Race Mode starts automatically. It asks questions at speed to test the students' memory and comprehension of the functions just covered, before continuing with new functions. At the end of the race, students can see how well they have done relative to their other races. The game gradually focuses on any functions that the students have difficulty recognizing, and speeds up as competence is gained.

By contrast to Race Mode, Story Mode slowly introduces new functions by saying them as the graphs are shown, allowing students to quietly look, listen and learn.

The game is controlled by on-screen gestures which are simple to demonstrate and easy to use, and the game can be played without voice prompts.
