Are you comfortable leaving sub plans? Are you rarely out and never think about what to leave until you're in the moment? This will help!
I was always an organized teacher and adamant about leaving as many resources as possible in any sub plans........until I was out for maternity leave earlier than expected, and simply couldn't remember if I left everything needed, thus resulting in ..... THE CHECKLIST!
Even if you think you don't need it....you probably do!
