Hi All I've been asked to develop a new, whole school approach to mental maths as it's been identified as an area of development. I've been told that each class will have a weekly lesson, dedicated to mental maths. Just wondered if any of you already do this, have any suggestions or advice as to what has/hasn't worked in your schools. Also, any resources/schemes that you have experience of. Just would really appreciate any ideas before I launch anything. Thanks!
