In order to make it culture-friendly educational materials were prepared with two widely used languages, Amharic and Afan Oromoo. First, the teaching materials were prepared in English then translated to Amharic and Afan Oromoo separately by bilingual experts. Then, different bilingual experts back translated to English. Finally, with these experts, common discussion was made and the final teaching materials were produced. The package of teaching materials includes booklets, fliers, and posters prepared in both languages.
