Ordering and Sequencing & Number before and Number after . This is a good one to practice when you are out and about. When you spot a number (door, road sign, number plate etc) say what the number before/after is or the number 10 before /after. If you are up for a challenge you could say the number 1.5 or 2.25 before/ after!
