tks for the advise…

Hi all, my girl is in primary one this year. Just in the first few weeks, I already struggling with her mandrian Hanyu Pinyin. Does anyone know whether is it appropriate to buy an electronic chinese dictionary now? So that I can actually check the pronounication and teaches her at home. And does anyone have any suggestion on the brand? Do you all think the school will suggest the buying at a later stage? Pls help…tks…
