The Yoshimoto Orton-Gillingham Maths Kit is a comprehensive set of colourful manipulatives that are used to assist in the development of the core mathematical concepts of number sense and number operations. They are an integral part of the multisensory maths program, linking the abstract mathematical skills taught with concrete manipulatives to support the development of conceptual understandings that can be difficult for some students to grasp. The materials can be used to develop knowledge on a range of concepts, from friends of 10 to multi digit multiplication and division, making their use versatile across a range of ages and learning stages. The kit has 3 levels of manipulative materials that are organised in coloured sets. They are stored in a strong case equipped with a carry handle that makes the kit easy to move from location to location..
