The Digital Warm-ups series of CD-ROMs features short activities that can be used as daily warm-ups in the classroom to get students motivated for new material or review what they have already learned. The warm-ups can be displayed on a classroom whiteboard, a computer projection device, or on an individual computer; they may also be printed. The activities can be completed as a class, a small group, or individually, and the topics covered include root words, prefixes and suffixes, compound words, synonyms and antonyms, parts of speech, figurative language and vocabulary. Quick links connect each warm-up to dictionary.com, and bold vocabulary words are also linked to definitions on the web. An answer key is also provided.
