What did i do wrong in this counting assignment?

Most of this, you did fine. BUT - the last bar of EVERY line should begin on 1, and have 2 and the subsequent beat numbers tied to it (some teachers - me, for example - have you use parentheses.) The third line - numbered 4 - second bar should be "1 + e 2 (3). IN the next bar, you did it correctly.

IN the last line- numbered 5 - the first bar is 1 e - e on the first beat. same in the second measure - 1 e - e. Third bar -0 you do not need the *ands*. You also wrote *ands* in the first bar of Line 4 - should just be 1 2 3. Every sound you write, shoudl reflect a NOTE written . I still do not write a NUMBER or anything else where there is no sound initiated - so even in Line 4, that sixteenth TIED to the eight - I would NOT write a 2 - or better, write it in parentheses. My basic rules are that EVERY initiation of a sound gets its correct notation under it - tied notes that fall on a beat, or multi-beat notes, also get beat numbers but in parentheses. to NOT write the numbers of every beat gets us lost!

Another thing that irks me is 1e+a. I use 1e+e. All sixteenth division get the same SOUND - there is no reason that one gets e and another gets a. That's just me - frankly,other counting systems like Gordon ( ask your teacher) work better. It's a big world - I made sure my students had some familiarly with a variety of systems.

So tell your own teacher that some retired theory teacher with multiple undergrad and graduate degrees in Music Ed and Music Theory told you this - but THEY are your teacher, and what THEY say, you do!
