Transition to Holiday
Sometimes what is good and fun for some children, is chaos and anxiety for others. So, I know that I up the preferred activities. If I know that one project would present too much of a challenge for a student, I will offer an alternative product, or an alternative place to do the work. An older student could support a younger one. Especially good, is an older student who is having difficulties with behaviour in his/her class. It is a great esteem booster if they can show some leadership this way.
Another suggestion, is to let go of the project, and build in helpful activities: working in the Library. We have reduced the task demand for many of our students who act out, and they are helping out. Some teachers may feel a little funny about 'letting them get away with work', but really the alternative is anger, acting out, anxiety and consequences. I find if I give a little free time, some hands on helping tasks (delivering, picking up books, sorting blocks, inventory, cleaning shelves, collecting materials for the office, they are willing to do a short task, as a break!
It works with most kids. Try it out and let me know how you reduce the chances of negative behaviours from anxious children.
