Audio tape designed to help children with some addition "math facts" and with skip counting as a preparation for multiplication further down the road. Simple songs are sung without accompaniment to familiar tunes. The tunes are rather catchy and we find ourselves regularly singing them around the house. (Such as the "9s" - 9, 18 and 27, 36 and 45, 54 and 63, 72 and 81, nine of them, round the sun, make their orbit one by one, nine of them, round the sun and counting them is fun). One side of the tape includes all of the songs sung by a simple tenor voice. The other side has the same songs played at a faster speed (which sounds something like "Alvin and the Chipmunks" for you Generation Xers.) There is another tape which I haven't reviewed which uses Biblical themes and tunes for the songs.
