I was observing a little guy in preschool who had just entered school the other day. He was still working on basic skills like following directions and had limited things that he could do to engage himself independently. The teacher was working on having him do a simple put-in task of putting cards in a coffee can, but because his skills were so limited, he was completing this task repeatedly throughout his day. This wasn't the only thing he was doing and there was time in the day when he was working on discrete trials for learning readiness skills, learning to wait his turn, and working on communication through a number of activities in his day. However, one way that he was working on communicating was to use the coffee can task, that he seemed to enjoy, to have him request the cards to put in from other students. That got me thinking about one of my pet subjects over the years--creating put-in tasks that are age-appropriate and have some variety for learners who are just starting to gain other skills. These are typically the types of tasks that we start work systems with because they are easy for students to do independently. You can see from the picture a variety of types of tasks and materials you can use. I particularly like the seasonal tasks like the jack-o-lanterns that the students is putting in for 1-1 correspondence (a little more advance than just putting in).
