*The case of maths rules* for primary school has arrived! You’ll find everything you need in it for revising the rules of maths and geometry, calculation procedures and summary tables with formulas!

For example, if you don’t remember how to classify, count, compare and order natural numbers or you want to revise how powers are calculated, go to the numbers section. Or let’s say you want to know how to calculate the perimeter or area of a polygon? Look up the rule in the space and shapes section, there are pictures to help you understand better too!

It’s easy to use: in each section there are plenty of rules to revise, from the easiest to the most complex. Each rule comes with an example and an easy-to-understand definition. If you don’t remember how to do a sum, check the procedures pages: you’ll find the calculation with a step-by-step explanation!

The case of maths rules

The case of maths rules contains everything you need for learning or revising the rules and definitions of maths and geometry, calculation properties and procedures, and summary tables with formulas.

Each page is dedicated to the explanation of a single **rule** or **procedure** and is introduced with a **cartoon** which illustrates the content, providing pupils with «visual hooks» which enable them to understand mathematical code better.

Each **rule** is presented on the page in the same way: the **title** of the topic, a **cartoon** which introduces the application of the rule, a numerical **example** and the **statement** of the rule.

The **solution procedures** for the calculations and problems are given step-by-step on the pages identified with the procedure label. The **title **on the top of the page identifies the topic, whilst the **numerical example** always appears alongside an **explanation **of what to do in each solution phase.

Each section has a different colour and presents the main rules of the topic it deals with

All topics follow an increasing level of difficulty in the same way as they are dealt with from year one to five at school
The case of maths rules is recommended for pupils with dyscalculia too. It can in fact be considered amongst "non-specific" or "functional" compensatory tools, which support deficient aspects of "transversal" skills such as memory, attention etc.
