Learn reading (in french)

The word sets are classified into 7 difficulty levels which follow the usual progression of the teaching of reading: starting by simple syllables (in P T M L R), then we go gradually towards more complex syllables. These activities were created voluntarily as part of the Afrikalan Project, which aims to make free educational software accessible in West Africa. They are distributed free of charge and in a non-commercial manner, under the terms of the GNU-GPL license.

The required Xposed variant to use is LSPosed. Other Xposed variants will not work. Additionally, this module cannot be guaranteed to work on all devices. In the worst case, it can cause a bootloop. Use at your own risk. To use Let Me Downgrade: 1. Install the JingMatrix LSposed fork. This requires your device to be rooted with Magisk or KernelSU. Installation instructions for LSPosed are available here. 2. Install Let Me Downgrade. 3. Activate the Let Me Downgrade module in the LSposed user interface. 4. Reboot your device and sign in. 5.
