The school system is an institution where teachers adopt different teaching methods to impact knowledge and skills. The teaching method adopted by a class teacher has a great effect on children interest, academic achievement and brain development of a child. To support this fact the researcher used two groups of children from ten schools to carry out a study. Five schools where used as control groups while another five schools was used as experimental groups. Both groups have a population of 400 pupils in the ten schools that were selected for the study. In carrying out this research, two research questions were raised to guide the study; with two hypotheses formulated and tested at 0.05 significant levels. Findings were discussed based on observations, and recommendations were made to guide the class teachers, parents, government and children on the importance of teaching aids in the teaching and learning of child development.
