Three teaching aids in astronomy are described. The first consists of a star locator with features of a transit, equatorial mount, and revolving star map for teaching celestial coordinates and identification of stars. The second is a set of black flash cards of common constellations, and the third is a rotating disc for practice in estimating standard time by the Big Dipper.
