The colouring and work-book edition!
Colour in the pictures and practice reading and writing by filling in the missing words.
Closely observing the shape and grouping of letters in order to copy them into the blank spaces -- with loving help from adults, of course -- prepares children for
both reading and writing. It makes children comfortable with books and pens, while the repetition of the task helps them memorise letters and spellings.
Because English and American spelling differs, there are two editions.
There's also a Kindle version.
