When I first started teaching (only a year ago!) I hated how long I spent making morning activities and then the children coming up and asking 'what do we do?' It is on the board of course but they never looked at it! So I started doing something similar to this half way through the year and found it was really helpful that the children knew what they were doing without being directed to the board as such!
It definitely takes a bit of training and some slides do need changing weekly BUT it takes a matter of minutes to change them.
There are further notes on some of the slides.
Oh and of course POLKA DOTS!
