Mots sans maux - Écoles is an educational application for children who are starting to learn spelling. It is designed to teach them how to spell the sounds of the words they wish to learn. The application consists of 5 educational games on the subject of lexical spelling, with a total of 10 words. Each word is learned by repeating it 5 times and by comparing two ways of spelling the same sound.

The 5 educational games are based on the following teaching methods:

A. Error-free learning: The child is taught by repeating the sequence of sounds until he/she can correctly spell the word.

B. Spelling by regularities: The child is taught by selecting words that have a particular spelling regularity.

C. By repeated exposure: The child is taught by repeating the sequence of sounds for a certain number of times.

D. By teacher/test: The child is taught and tested in close intervals.
