Identity as the first unit of the year.
The first three weeks of every Spanish class are the same. Names, ages, where everyone is from. The teachers who do it well treat identity not as a vocabulary list but as the most important thing the class will talk about all year. These resources are built that way. Heritage variants. Real questions. No worksheets that ask which of these is your favorite color.

The first one is a four-day mini-unit on La identidad personal (AP Theme 5) that doubles as the first unit of a Spanish 3 year. The Novice version (Mi familia y yo) follows. Both ship before August.
Every Spanish teacher hits the morning when the kid is throwing up at 5:30am and you have not even thought about what period 1 is going to do.
A good single lesson is not a worksheet.
A mini-unit is the right unit of work for most of the year.
AP Spanish is the test that pretends to be a course.
