Here is a photo of my most recent Maths display centred around Place Value and Measure. I have included some things on my display which I will keep on there all year round as they are useful essentials which I will be referring to regularly in my teaching. Others will be taken down and replaced with other things relating to new maths units covered.
The middle of my display was left blank deliberately to be used as a working space where current tips and steps to success could be displayed clearly. You don't have to cover all of your displays - leave some spaces blank for success tips to be displayed each lesson. I have also pinned up some of the children's extra homework they have sent in as good examples of maths homework!
