Why is it important to use a variety of materials in the classroom?

People in general learn differently. Each person have a learning style that will predominate to favor learning in a specific way. Using only textbooks in the classroom will only help those students who have that certain type of  learning style but what about the other students who need more visual aids and interaction in order to learn? 
As teachers we face a challenge of providing our students with enough learning scenarios and opportunities so they develop integrally and learn in meaningful ways.
Teachers as well as school administrators are responsible for choosing materials that are age and developmentally appropriate for them and that will guide them through paths of learning. 
This blog has been designed with the purpose of sharing some ideas that we have as future teachers in order to make changes to our teaching practices and show some aspects we have been learning about that might help other teachers on this matter too.
