Brian P. Cleary has written a slew of fun, informative and attractive "non-fiction" books! His Words Are Categorical books - all found in or around J 428 CLE - make grammar fun and easy. Each book handles a different part of speech - nouns, verbs, adverbs, pronouns, adjectives...the list goes on and on.
Cleary also has a math series, Math is Categorical. The Parkland Community Library only has 3 of these titles. The books can be found in Juvenile Non-Fiction in the Math section (around J 510 CLE) and, for some reason, in J 530.
Cleary also has a series of phonics books that the library has on order, Sounds Like Reading. Look for these books in late September, early October.
