The magnetic board was what prompted me to make a purchase. Sadly, the number of words available are either too repetitive (ie, at, the, is, of), or so limited that they don’t even offer basic words such as “those, that, there, where, when” enough so a child can explore sentence structure with their vocabularies with the magnetic board. The book, however, was very well structured and theory based, more suitable for school age children around age 7 when they have achieved a good foundation of the English language.
