The braille course offered by the Hadley Institute for the Blind and Visually Impaired consists of multiple parts, and you're expected to take your time with it, so I'd recommend you consider it for her.
Braille cards will have correct spacing if you buy them from a reputable supplier. I recommend MaxyAids, Independent Living Aids, LS&S and the National Federation of the Blind Independence Market.
