This is a vocabulary learning course targeted at a 6th grade level. Examples of the words included in this course are arid, thesis, hazardous, verdict, nationality and ratio. Words are examined in multiple ways to reinforce learning, since you need to be exposed to words 10-20 times in different contexts in order to understand new vocabulary and then use it appropriately. For example, words are used with their definitions as you might expect, but then word origins, sentence usage, similar words and other activities are used to help word learning. This is an ideal way to broaden your child's vocabulary in an interesting and stimulating way. Of course, the target 6th grade level is a broad estimate and most children between 5th and 8th grades should be able to improve their vocabulary to some degree with this course. It is also part of a series with a specific audiobook for each grade level.
