As a class we have spoken about subtraction and many of the children have had a go at taking away practically in the classroom using the resources we have in the maths area. I would like the children to watch the ppt and talk to you about what subtraction is and what it means. Show the children the symbol in case they can't remember what it looks like.
Once they have watched the ppt I have attached a different range of sheets for the children to have a go at or they can complete the activity using resources and you can make some subtraction number sentences up for them and do this in more of practical approach.
Let me know how they get on.
