 Hello, my name is Carol Handyside and I'm Louise Langford. We would like to share with you our new publication, A Deep Sense of Number, Starting with Docs. We have developed this resource out of our shared experience of teaching maths. We discovered that an underlying lack of number sense has a marked impact on progress, which presents itself with difficulties in many different areas such as place value, problem solving, estimation and an understanding of the four operations, which ultimately impacts on understanding and success in concepts such as fractions and algebra. In our experience, number sense is the foundation of later mathematical concepts and therefore so important to secure early in a child's maths journey. If you are interested in making a difference by ensuring all your pupils have a deep understanding of number sense through developing their conceptual understanding of number, then this accessible book full of practical, tried and tested activities is definitely for you. This resource combines many years of research practice from a range of specialists, such as Jenny Beck, who we are very grateful to for the confirmation that the ideas are founded on sound research. The book is ideal for early years and Key Stage 1 teachers, learning support assistants and specialists, as well as professionals working with older pupils to not only appreciate the development of number sense and how future concepts can be built on these early ideas, but also support any pupils who may have missed out on the early acquisition of number sense. The resource guides teachers through activities to develop number sense, beginning with guidance on how to draw on children's innate skills of subortising or just knowing the amount without having to count. The structure of the book follows a child's development of number sense, incorporating discovery learning and mathematical reasoning. The activities can be accessed at any point depending on the needs of the child. Fingers are a key component of early maths teaching and there are activities to encourage efficient and effective use of finger patterns. The book then develops a deep sense of number, initially securing familiarity with dice patterns linked to finger patterns and introducing the Hungarian number frame. There are loads of activities to develop a more flexible representation of the same number and allow children to see numbers both as composite parts and as a whole. All activities are easy to follow and can be used with readily available materials. The resource includes printouts of the frames in the appendix. The resource is perfect for those new to using the Hungarian number frame or anyone looking for more ideas on how to use it effectively. There are activities that model how to link the Hungarian number frame to the tens frame using both the five-wise and the pair-wise pattern. Using a variety of activities in the book with the different frames, you are able to support children to internalise and visualise the dot patterns in order to develop number sense. The book helps you to choose the structures to expose the relevant maths as well as encouraging mathematical talk and reasoning. The activities within the book promote a blended multi-sensory concrete pictorial abstract approach that incorporates application and communication in every lesson. The book then builds on this, exploring the four operations through activities that enable children to make connections and verbalise their thinking. Firstly, looking at addition and subtraction. Then multiplication and division. The activities build on the idea of part-whole relationships in order to support the children with using numbers flexibly to calculate, not count when solving calculations. The book is packed with a collection of innovative ideas to develop number knowledge and how to support children to derive new facts from known facts as well as apply this to calculations. From our experience, we know that through exploring the range of activities, practitioners will build an understanding of how these early skills and number sense lay solid foundations for future concepts and this will give children the best start in their mathematical journey.
