Young children’s proficiency in English and their vocabulary development are predictors of their early school achievement. This paper reviews general guidelines and activities that can facilitate young children’s receptive and expressive vocabulary and language development. While vocabulary development is an essential element in children using language to enhance their reasoning, it is only one element of a set of elements that connect children’s language and reasoning together. From this perspective, Marion Blank (2002) has theorized four levels of language and reasoning that are hierarchical and that can be progressed using child and adult dialogue and talk. Examples are presented on how these four levels can be incorporated into early childhood learning settings.
