'brush your teeth' pupils continually reminded

I found this poster in front of a classroom at Mwambao primary school in Bagamoyo district- Tanzania. I felt it was relevant as a starter "Brush your teeth daily using a tooth brush made from a tree 'stick' or a plastic one" to the local settings and it was placed at the right place with all the prominency - in front of the classroom, just beneath the school timetable adjuscent to the writing 'black' board.
