In a Hindi language textbook at primary level, which do you consider most important?

A good primary-level Hindi textbook should expose children to the rich diversity of Hindi—different genres, registers, dialects, regional flavors, prose and poetry styles. This broadens linguistic exposure and develops genuine language competence. Famous writers may not be developmentally appropriate, moralistic content is pedagogically narrow, and abundant exercises are mechanical. Diversity of language forms best supports rich language development.
