Sometimes the best way to understand a concept is to consider a non-example, or opposite. This series of bilingual readers does just that.  Colorful pictures illustrate “Up and Down”, and the bold text sentences describe the pictures. Seesaws go up and down, just as kites go up and down and dogs can jump up and down.  This series would be useful in Kindergarten, where the concept of opposites is taught. It would also be a great idea in first grade, supporting the acquisition of Spanish, while reinforcing the concept of “opposite”. Picture glossary and index included. No A.R. test located.
