SHADE or SHADOW?

A shadow is the silhouette cast by an object that blocks a source of light. You can see your shadow on the ground or a wall or whatever you are blocking from the light source. You can make shadow puppets with your hands. A shadow can be cast by any light source such as a candle, a flashlight, an overhead light, a spotlight, or the sun.

Shade is the "darkness" created by a shadow and only really applies to shadows created outside by the sun. Underneath a tree on a sunny day would be "in the shade". Inside a building would be "out of the sun" and not "in the shade." However, under a roof with no walls (like a picnic shelter) would be "in the shade."
