Teaching Number Composition in the Early Years

Often referred to as trusting the count, number composition is one of the most important understandings we can build in the early years—it underpins everything students go on to do in mathematics.

In this webinar, we’ll look at how students develop this understanding through subitising and partitioning, and how this fits within a clear instructional hierarchy.

We’ll work through the full journey together—what this looks like in planning, how it plays out in the classroom, and how to assess whether students are actually developing secure understanding. This includes looking closely at examples and non-examples, as well as practical, ready-to-use tasks.

The focus is on making this work clear, manageable and immediately applicable, so you can support students to move beyond counting and genuinely trust the count.
