Help children read and spell longer, more complex words, by building onto root words with prefixes and suffixes. They begin by adding simple inflectional endings, then common prefixes and suffixes to root words. They might turn play, for example, into a dozen or more words, including plays, playing, playful, displaying, and playfully. Soon they are building powerful words such as con-struc-tion and de-part-ment. Once children learn to construct big words, they will be better able to deconstruct big words they see in their reading into manageable word parts. Includes 60 hands-on lessons in which students create over 500 words.
