Independence and time management

I find that prioritising and time management can be very hard for some of the children in my class (especially since some lack a sense of time and anything longer than 5 minutes may as well be hours). For these kids I help to list ‘must dos’ in priority order. However, they will usually only get through one task (and only in the last 5 minutes of the session) and never have any time to get to choose ‘can dos’. They recognise that they are missing out on getting to choose, but can’t plan ahead enough to complete their work. The only way I’ve found to work is to have them working close to me so they think I’m keeping tabs on them.

What are some strategies you have with helping children manage their time and work independently?
