摘要：AbstractThis paper acquaints readers with the sub-results of the research survey, which was primarily devoted to the issue of acquiring pre-numerical imaginations of children with hearing impairment in pre-school age in the Czech Republic. In addition to the established time, the extent of their hearing loss, or type of a compensation aid, the indispensible factor affecting the level of pre- mathematical imagination of children is family environment and the communication mode which is either used in its natural way or selected by the parents of the child. The survey study results of 12 deaf children and the control group of intact peers confirmed the dependency between the level of acquired language skills and the level of acquired pre-mathematical imagination.
