The Classically Cursive series teaches a handwriting style quite similar to that of D'Nealian. It does not teach manuscript, except in a very cursory fashion in Book I, and focuses entirely on cursive. The four books offer a fair amount of content, working with letter shapes, connections, and then words, before it goes on to some Bible verses (NKJV), the ten commandments, catechism questions and attributes of God.
Book IV should also be called a copy book. It concludes the series with questions and answers regarding the attributes of God—His existance, omnipresence, immutability, holiness, power, wisdom, dominion, love, goodness, and patience are all discussed.
