This beautiful book by Michael Grejniee follows two children through their day using opposites. The vocabulary is practical and it is wonderfully supported by the illustrations. The meaning of each simple sentence is reinforced by the contrast to the opposite.

For example: Estoy adentro. (I’m inside.) The illustration shows the little girl playing in the house. Estoy afuera. (I’m outside.) The illustration shows the little boy playing in the yard.
