I usually start from 1 year to teach my children Identification of OBJECTS IN THE HOME. I pronounce all the objects to them clearly like chair,table,cups etc. This act help to keep them focused in whatever anyone is saying to. It help build their co ordination because they will be calm while listening as you pronounce. The essence of using Educational Materials while teaching anything is to draw the attention of the learners and make them to understand fully what you are saying. With these my method Identifying anything is usually simple to them unless you didn't show them that object. Chinwe Blessing (Raise a Genius Kid Africa Facebook Group)
