Music sure has the power to keep facts in our memories! I can still recite the names of the islands of the Pacific just from hearing the song a few times. 23 melodies are catchy, not rock. Great for car trips or background while children are drawing. Soon they'll know the continents, oceans, famous landmarks, planets and 225 countries without much effort. Accompanying 69 page workbook has puzzles, maps, crosswords, and other activities to correspond with each song. A very useful geography help!
