Although the factual presentation of the material in both additions to the True Books Series is accurate, the illustrations are prosaic. Man's transportation as presented is pretty dull reading. Both books are useful in social studies units, for they are simple reading, with large type, easy vocabulary and brief sentences. The True Book of Houses covers tents, adobe houses, grass huts, sampans, yachts, houseboats, sod houses and tepees, with text for children in the first two grades. Useful in the classroom, one could wish for less cluttered format. Firm stitching.
