This cube game set undertakes to efficiently educate and facilitate development in the area of mathematics. The objective of mathematical education is for the child get to know the surrounding world actively and explore observable relationships in it, to make them able to describe, compare and organise the elements of the world, to develop their problem sensitivity and problem-solving abilities. In summary: the child will be able to map the world using mathematical concepts and thinking. Naturally these competences can only be built from an elemental stage, the groundwork for which is already laid in nursery school mathematical education. At this age, sufficient playful practice can result in considerable developments.

József Nagy et al. cited eloquent proof of this regarding the impact assessment of PREFER/DIFER. They confirmed an acceleration of one mental year in this skill area in the past quarter century. At the same time, they emphasise that a third of children entering primary school do not reach the level of maturity necessary for successful learning in mathematics. Therefore there is a need for the multi-faceted and playful developmental education of counting skills at nursery and primary school levels. Furthermore, children with counting difficulties or disabilities (dyscalculia) will need basic developmental education at an older age as well, and the present game cube set offers exhaustive opportunity for this.

The CleverCube tool for the development of counting skills consists of 6 main groups of cubes (sets). These ensure the development of mathematical thinking in a diverse way in the following areas:

**To
track and facilitate the development of counting skills:**

- Determining more, less and equal perceptually
- Interpreting mathematical concepts, for example even, odd, etc.
- Knowledge of the number sequence
- Counting quantities
- „Navigating” the number sequence
- Knowledge of number images
- Recognising images of numerals
- Quantity invariance
- Establishing the concept of numbers
- Distinguishing between cardinal and ordinal numbers
- Applying mental operations (grouping, ordering, abstraction, comparison, differentiation, analysis, synthesis)
- Executing operations. Adding,
taking away, breaking down by transforming sets, and using number stairs (Stage
I in the development of thinking –
*see description of the stages in the manual for the Story comprehension cube set*) - Executing operations by using number images (Stage II in the development of thinking)
- Executing operations. Verbally applying addition, subtraction and breaking down numbers (Stage III in the development of thinking)
- Interpreting and applying multiplication
- Interpreting and applying division
- Interpreting the relationship between fraction and integer

**Measuring and
developing basic geometrical skills:**

- Distinguishing and identifying two-dimensional shapes
- Interpreting and applying the concept of symmetry
- Determining the location of objects and points in a coordinate system.
