Prepare your children for finding one more and one less than any given number within 20 with our Year 1 1 More and 1 Less Prior Learning activity. This covers the objective of finding one more or less from a group of up to 5 objects, which is covered in the previous year group. This will assess your pupils' basic understanding before moving them on.

Set up these activities in provision at the start of your week, or deliver in small groups as a pre-teach. The choice is yours!
