The paradiddle is a rudimentary technique for all types of drumming. It is something you should have in your repertoire. It is very simple and you should practice this regularly. A paradiddle consists of two single strokes followed by a double stroke, i.e., RLRR or LRLL. When multiple paradiddles are played in succession, the first note always alternates between right and left. Paradiddles are often used to switch hands. In the chart below, you start with your right( or dominant) hand and alternate to left(or other) hand and then hit twice with your right hand. Then alternate hands. Do this exercise with the tone only. Keep a steady beat and tempo. Increase the tempo as you get better.
Keep practicing and have fun.
