Here is a practical activity you can use with a small group to encourage children to compare groups of up to 10 objects. This Year 1 Compare Groups Supporting Activity contains step-by-step instructions on a simple activity that will prompt children to check if there too many, just enough, or too few objects for each child to be given one each.
The resource is quick to set up and is perfect for using to recap previous learning, or to embed learning in a practical way during a maths lesson.
