Bilingual Hispanic kindergartners do not automatically read pictures silently in their second language, English. The students may not understand what “apple” means, but the general outlook in education is to give them the tool and say, “They’ve got to grow into it.” However, there is a more efficient method.
But alternative Pan-American images have space for a Spanish self-voice. “B is for boat/barco” present a common sound (B). This is not a tool they have to grow into.
Learning familiar Spanish/English letter sounds becomes overly complex if bilingual Hispanics are only exposed to traditional sound clues with conflicting letter sounds – BEAR (oso), BUTTERFLY (mariposa), etc. There is an ABC fast track option available to Hispanics which other ESL students do not enjoy, and those are Cognates.
In addition, the English-only requirement of traditional examples is so difficult for bilingual five-year-olds that a “Forget Spanish” message is sometimes perceived, carrying another set of perils.
