Educational system, method, and apparatus

A method, comprising:

• providing one or more first sheet members including a first side and a second side, the first side and the second side each having a plurality of first markings that each indicate a first measurement unit, and one or more first attachment portions disposed along some or substantially all of a perimeter of the one or more first sheet members;
• providing one or more second sheet members including a first side and a second side, the first side and the second side each having a plurality of second markings that each indicate a second measurement unit, and one or more second attachment portions disposed along some or substantially all of a perimeter of the one or more second sheet members;
• removably attaching the one or more first sheet members and the one or more second sheet members, via the one or more first and second attachment portions of the one or more first and second sheet members, to form a first shape;
• removably attaching the one or more first sheet members and the one or more second sheet members, via the one or more first and second attachment portions of the one or more first and second sheet members, to form a second shape, which is different from the first shape;
• summing the first measurement units and the second measurement units of the first shape to determine a first sum;
• and
• summing the first measurement units and the second measurement units of the second shape to determine a second sum;
• wherein the first measurement unit is equal to the second measurement unit;
• and
• wherein the first sum of the first shape is equal to the second sum of the second shape.

An educational apparatus, comprising:

• one or more first sheet members including a first side and a second side, the first side or the second side having a plurality of first markings that each indicate a first surface area unit, and one or more first attachment portions disposed along some or substantially all of a perimeter of the one or more first sheet members;
• and
• one or more second sheet members including a first side and a second side, the first side or the second side having a plurality of second markings that each indicate a second surface area unit, and one or more second attachment portions disposed along some or substantially all of a perimeter of the one or more second sheet members;
• wherein the one or more first sheet members and the one or more second sheet members are configured to be removably attachable to each other in a first shape by the one or more first and second attachment portions of the one or more first and second sheet members;
• wherein the one or more first sheet members and the one or more second sheet members are configured to be removably attachable to each other in a second shape, which is different from the first shape, by the one or more first and second attachment portions of the one or more first and second sheet members;
• wherein the first surface area unit is equal to the second surface area unit;
• wherein a first sum of the first surface area units and the second surface area units of the first shape is equal to a second sum of the first surface area units and the second surface area units of the second shape;
• and
• wherein each of the plurality of first markings and the plurality of second markings is one of a square having a surface area equal to the surface area unit or a triangle having a surface area equal to one-half of the surface area unit.
