Code secret

The tablet application offers for each referenced student the discovery of a secret in the form of: - word (in uppercase script, lowercase script or lowercase cursive), - number, - result of an operation (addition, subtraction, multiplication or division) Aids can be activated or not for each student: - the letters / numbers can be displayed or not beforehand as you go, - the letters / numbers can be pronounced or not to help the search, - the keys with the letters / numbers are presented in alphabetical order or randomly mixed (in a different way for each child, so that a child passing after another does not identify the key by its position on the keyboard)
