I grabbed a selection of bits from around the house, there is really no need to go out and buy anything especially. Don't have a white board? Use paper. Don't have any flashcards? Make your own. Add dinosaur figures to make it an inviting play space. I provided D's in an assortment of fonts as an extension (no photos, but I printed them of from google!) of this activity for Jenson and Evie, as I know that at school they try to show that no all letters are written how they think they are written.
This little station went down really well and stayed up for a good few days before they started to get bored of it, I will definitly try it again when we move our focus onto space next month.
