Depending on the age I would use some of the lip slurs with a mixture of playing and buzzing from the brass and woodwinds being pitch centers, (during buzzing). Example - WW played 1235 while the brass buzzed 1 then played 345. If I had younger kids maybe only the first 2.
For more advanced lip slurs those would work in as the year progressed with a similar process to page 6.
We then would vary the exercises in the different keys depending on our goals. Early on we focused on Region scales. Later on we would target Sight-reading keys and the keys our music, (Fall, Christmas, UIL), and we would finish off the year with all of the remaining keys making sure we hit all of them every year.
When I had shorter classes we might do long tones, 1 set of lip slurs, and a few exercises in one key. When I had longer classes I could do more of the lip slurs and 2 or 3 keys worth of exercises.
