Richard, I would try using objects that relate to their career fields as you move through them through the math concepts. If they are in the medical field use medical examples and manipulative objects. If construction use construction. The big difference between children and adults is that adults are taller. This means that you can use objects and involve them in a tactile way by using items that are seen as being age appropriate but still get the key math concepts across. I use a lot of games and rewards in my classes and my adult students really respond to earning rewards such as candy kisses for performing a function, task or procedure. Have fun with your thinking and your creativity will kick in. Go to websites that offer activities for teaching elementary math and you will see a host of things that you can make age appropriate and can use in your classroom. Some of my best received activities originated in the elementary classroom. Gary Gary Meers, Ed.D.
