"El mundo de los deportes" SERIES: Deportes de invierno, Deportes de verano, by Isidro Sánchez and Carme Peris
These two fun books are perfect for elementary and level 1 Spanish (Deportes de Primavera and Deportes de Otoño don't seem to exist - anyone know why?) The illustrations are fun and very kid-friendly, and can be used as the basis for description activities and a seasons unit. Most of the text is simple, though some vocabulary might need tweaking and/or pre-teaching for beginning proficiency students. For example: "Siguiendo las instrucciones de monitor, no es difícil aprender a coger los bastones y a situar bien los esquíes." A lovely series published by Barron's.
