Material usage in lessons in the primary schools is very important in order to enable primary
school students to concretize abstract concepts, to assist their learning process, make it easier for them to
remember new information, to encourage their involvement, to increase their self-esteem, to be cognizant
of individual student differences, to provide a useful set of underlying theoretical principles that focus and
enhance the characteristics of the planning and the pedagogies for learning (Conners, Nettle & Placing,
1990).
