Gamma Geminorum is Pollux's left foot, and the third brightest star in Gemini.

To find gamma, start at Procyon (alpha Canis Minoris). With the naked eye you'll find a triangle formed by Pollux to the north and Alhena (gamma Gem) to the northwest.

In binoculars you'll see its attendant star, xi Geminorum. Now if you draw a line from xi, through gamma and to the northwest, you'll encounter mu Geminorum, the left foot of Castor. (Or just move the binoculars up, putting gamma at the bottom of your field of view; mu will be at the top.)

We can now fill in the rest of Gemini's details. From Alhena (gamma Gem), move half way up to Pollux. This is delta Geminorum (Wasat, The Middle).
