With Tangia, students learn vocabulary through a study of English words with Greek and Latin etymologies, of which 80-85% of the more difficult English words are composed. With each set of key prefixes and roots, students move through eight different learning modes, culminating in a challenging game at the end. One or two students can log in at each computer station and full data tracking exists for all of their scores. There are two units (Greek and Latin) with 10 lengthy parts in each.
