We all try our best to not forget anything but sometimes we just miss things. That's why I made this post-it note 'to do' board. In an EYFS classroom there are always post-it notes around meaning they are an easy thing to write quick notes on.
When I've made a note, I can quickly stick it on my 'to do' board without much disruption to whatever I'm doing at the time. You could make this with any design using craft paper or anything that you have to hand.
