This book builds on the foundation laid in our earlier books Subitizing — Laying the foundations for number sense and Conceptual Subitizing — Laying the foundations for mental computation.
Subitizing and number strategies are now further developed to include rainbow facts, near doubles and near-rainbow facts. Use of the Secret Code and mini-chunking further extends this thinking. It is crucial that students have fluency and flexibility with number facts to 12 in the first instance and then to 20 as all later operations are built around these.
This page is where you can buy this book and its accompanying dot and number cards as a bundle.
