Role for Instructional materials

I learned this very important information when I had my masteral studies. As teacher it is a must for us to have an instructional materials for our students to learn more. There are learners who are visual means they learn most when they see drawings, videos or writings. Like in my case I am handling grade 7. They are like elementary they dont understand mostly if you just talk that is why you need to write on the board or present a powerpoint or visual aid. As teacher it is not easy to prepare such instructional materials but it will help us to deliver the lesson in time and much easier because it serves as a guide much more to the neophyte teachers.
