These grooves still have your lead hand on the hi hat, your following hand on the snare drum (playing a 'back-beat on '2' and '4'). However, your lead hand is playing a combination of 8th notes and 16th notes. The count for this will be 1-and-a, 2-and-a, 3-and-a, 4-and-a (think ... ham-burger, ham-burger etc if it helps!). We can now start to put the bass drum underneath this pattern.
REMEMBER : The count for all 4 of the 16th notes on each beat would be '1-E-and-a, 2-E-and-a etc.
