I have a student who has a bit of trouble tracking rhythms, often pausing between measures. I recently introduced eighth notes to him and we worked for a number of weeks on tapping these eighth note rhythm drills.
I then developed a series of 2-handed eighth note drills to help him track rhythms between the hands. These can also be used for rhythm duets.

Eighth Notes 2-handed 1 (or duet)
Eighth Notes 2-handed 2 (or duet)
Eighth Notes 2-handed 3 (or duet)
These exercises are such a great learning tool. My students have fun playing them on the piano!
