I learned three ball juggling as a kid thusly:

- with two balls in one hand, toss the ball closest to your fingers up and let the rear ball roll forward

- be able to catch the just tossed ball (or bag, or fruit) in the rear of your palm, where the other ball just rolled from

- be able to do this repeatedly in each hand. You are juggling two balls with one hand.

- now just pass the tossed ball between hands and you are juggling three balls
