Rules & Geometry

From primary school and throughout their education, mastering mathematics requires learning precision drawing. For a student, having to draw perfect circles or measure an angle with faulty equipment can quickly become a source of frustration. A ruler that breaks easily at the bottom of a backpack, or a compass that slips during drawing due to a loose hinge, are recurring problems that hinder concentration in class. Equipping oneself with reliable, durable, and easy-to-handle tracing instruments is therefore an essential step in preparing for the back-to-school season with peace of mind and ensuring success in scientific subjects.

The Rulers & Geometry collection offered by Wlidaty brings together the excellence of school supplies to meet the requirements of students and teachers. We have selected reference brands such as Maped, Staedtler, and Erichkrause, recognized for the robustness and precision of their geometric measurement tools. Whether you are looking for an unbreakable ruler capable of withstanding the busy life of a schoolchild, or a high-precision mechanical compass for technical drawing in middle school, our range covers all school math equipment, combining functionality, safety, and attractive design.

Essential equipment for a complete geometry kit

Our catalog offers a variety of solutions to adapt to each school level:

• Rulers and double decimeters: available from 15 to 50 cm, in a classic rigid version or in flexible material (Twist'n Flex) that bends without breaking. They feature UV-resistant graduation for perfect readability over time.
• Learning and precision compasses: from simple ring models to fit any pencil, to metal versions equipped with a locking system (Stop System) to maintain a constant radius without tension.
• Set squares and protractors: available in transparent plastic to facilitate the reading of underlying drawings, the plastic set square (45° or 60°) and the 180° protractor are the pillars of geometric construction.
• Geometry sets: complete tracing kits, often offered in cases or a metal storage box, gathering everything needed so nothing is forgotten at home.

Our tips for choosing and maintaining your child's equipment

To ensure the longevity of your technical drawing supplies and facilitate your child's daily life, here are some useful recommendations:

• For young children in primary school, prioritize flexible material (like the Twist'n Flex range). It resists twisting and avoids the problem of a broken set square in the backpack, which is very common at this age.
• Choose rulers with an ergonomic non-slip grip or clear visual cues (like a mark every 5 cm) to help the child if they have difficulty reading measurements.
• For middle school, opt for a metal compass with a branch locking system. This prevents the distance from changing during rotation, guaranteeing flawless circular arcs.
• Always keep instruments with a point (compass) in their protective case to avoid puncturing the pencil case or injuring the child's hand when they look for their equipment.

What is the difference between a 45° set square and a 60° set square?

The 45° set square is shaped like an isosceles triangle (two sides of the same length and two 45° angles). The 60° set square (or scalene set square) forms a right triangle with 90°, 60°, and 30° angles. Teachers often ask students to have both to perform all the geometric constructions in the curriculum.

How does a compass with "Stop System" work?

This innovation (common at Maped) allows for locking the width of the compass branches. Once the radius is chosen on the ruler, the child lowers a small lever or a thumbwheel. The compass then remains fixed in this position, preventing the lead from slipping or the angle from closing while drawing the circle.

Why choose a transparent plastic ruler rather than a metal one?

The transparent plastic ruler is ideal for learning because it allows the student to see what is underneath the instrument. They can thus perfectly align the edge of their ruler with a point or a line already drawn on the sheet, ensuring much better precision in their work.

Do the graduations on rulers fade over time?

On entry-level equipment, friction in the pencil case can erase the ink. However, the rulers selected in our catalog benefit from high-quality marking, often embedded in the plastic or treated to resist friction and UV rays, guaranteeing optimal durability.

What is the price of a good geometry kit on Wlidaty?

Prices depend on the technical nature of the products, the material (flexible plastic, metal), and the composition of the sets. We invite you to browse the detailed sheets of our online store to discover the prices of our compasses, rulers, and geometry sets currently in stock.

Offering quality instruments to your child gives them the confidence necessary to approach mathematics with enthusiasm and precision.
