Autocorrecting device comprising a support; at least two constant-diameter objects that can be rotated, at least one of the objects being referred to as determinant, the other at least one object being referred to as determined, each of the objects being provided with at least one stimulus associated with an angular position of the object; a drive means for driving the objects in rotation and having an object-driving torque M; a rotational blocking means for angularly blocking a determinant object in position; a selection means for selecting an angular position of a first object with respect to a second object, the selection means applying a resistive torque Cr between the first and second objects the two objects having a coupled position in which the resistive torque is higher than the driving torque M and an uncoupled position in which the resistive torque is lower than the driving torque M.

Certain exemplary embodiments can provide a device comprising a flexible core, the flexible core having a surface that acts to resist, but not to prevent, sliding of a plurality of objects thereon. Each of the plurality of objects is slidable along the core. The device comprises first end piece is coupled to a first end of the flexible core, wherein the plurality of objects cannot move past the first end piece.

An educational kit for teaching mathematics includes easily manipulated elements, which serve as cognitive reinforcement during the learning process. These physical elements are used in conjunction with a set of grouping rules. The educational kit and corresponding grouping rules determine a model and process to represent both an algebraic linear equation and its algebraic solution. A simple element, such as an item/figure including a variable “X”, is used to denote the unknown quantity. An item/figure including a number is used to represent a numerical value. These items/figures contain the exact elements used to form the expressions of the linear equation and are not items/figures that simulate the elements that form the expressions of the equation. By the use of this educational kit and associated grouping, students learn to simplify a given linear algebraic equation to the point where the solution is obvious.
