Abstract
A blocks assembly is provided. The assembly is formed of a base with an arch attached thereto. A number of blocks are slideably attached to the arch and confined by the base. The blocks can be slid from one side of the arch to the other. Markings on each side of the arch indicate how many blocks are on each side of the arch. Addition, subtraction, and general mathematical principles and relationships can be taught by movement and manipulation of the blocks.

A blocks assembly consisting of:
- a base;
- an arch comprising two legs and a connector joining the legs at a proximal end of each of the two legs, each of the two legs being connected to the base at a distal end of the respective leg;
- a plurality of sequential numerical markings on each of the two legs, the numerical markings arranged in sequential order starting from the base and increasing in number as the numbering approaches the connector;
- a quantity of ten blocks, each block defining an aperture through a height, the arch passing through the aperture of each of the ten blocks, wherein each of the ten blocks is slideable along the arch between one leg and the other leg;
- wherein a quantity of the plurality of numerical markings is equal to one greater than the quantity of blocks, the plurality of numerical markings starting at zero and counting up to a number which is equal to the number of blocks, each of the plurality of numerical markings spaced apart from an adjacent one of the plurality of numerical markings by a distance that is equal to a height of one of the plurality of blocks.

A blocks assembly consisting of:
- a base;
- a sliding track comprising two legs and a connector joining the legs at a proximal end of each of the two legs, each of the two legs being connected to the base at a distal end of the respective leg;
- eleven sequential numerical markings positioned on each of the two legs, the numerical markings arranged in sequential order starting from zero at the base and increasing in number to ten as the numbering approaches the connector;
- ten blocks, each of the blocks slideably connected to the sliding track allowing movement of each of the blocks between one leg and the other leg;
- wherein each of the numerical markings is spaced apart from an adjacent numerical marking by a distance that is equal to a height of one of the ten blocks.
