I have mentioned earlier that it is not easy for a teacher to obtain commercially published materials that will cater to his/her students' specific needs pertaining to the skills that the teacher is focusing on. Commercially published materials first of all can be quite expensive for the teacher to use in just one particular lesson.
Besides being expensive, the materials published usually do not cater to the needs of students with regards to a variety of aspects. The first one, they often do not cater to the students' local background. It is true that there is a certain benefit to learning something different but for starters, students should be introduced to things that they can readily relate to.

The last but definitely not the least is the lack of versatility of the material. A teacher would expect that a material bought (usually expensive) would have the quality of being versatile whereby it can be used for more than one purpose. However, the nature of commercially-published materials is that you have to buy different materials for the different objectives that you may have.
Hence, it is always a good idea to put in some effort to come up with one's own material that can cater to all the aspects mentioned above. Not only do these sort of materials provide the teacher with a sense of satisfaction, they also have the security of having ready resources on hand when ever they go into class.
