Here is a cute sign-up you can have out for Meet N' Greet or Open House for parents to indicate which jobs they could help with. I am more than happy to add jobs on here that you would like!
Copy Master: Can help with copies, stapling, laminating
Party Thrower: Can help with parties in the classroom
Pinterest Lover: Can create/put together the outside bulletin board or door
Fluency Timer: Can test students in their reading fluency
Fact Feeder: Test individual students in their math facts and help them record results.
Librarian: Can help organize the classroom library or run to the public library for additional items
Center Leader: Can conduct a center with given materials.
Also a spot for parents to indicate that they would like things sent home to work on!
