Kidioms – An Introduction to Idioms for Kids The Kidioms iPad app makes learning idioms fun for children, ELL students, or anyone wishing to improve their understanding of English. The app uses an interactive notebook to present an idiom, it's meaning and an example showing the idiom used in context. Each page of the notebook also has a graphic to help illustrate the idiom’s meaning. In addition to the lessons, Kidioms offers three interactive activities to help reinforce the concepts and provide practice using and understanding the idioms. Word Drop challenges the learner to complete the idiom by choosing the correct missing word. Missing Word asks the user to spell the missing word. In Match-Up the player selects the correct idiom to fill in the blank in a larger block of text. Common Core Standard that are address by Kidioms: Vocabulary Acquisition and Use Grade 3 •L.3.5.
