A first measurement scale is provided in which a plurality of uniquely color-coded base units of measurement are periodically disposed on the base medium. A second measurement scale, uniformly aligned and adjacent to the first measurement scale includes a plurality of color-coded subunits of measurement periodically disposed on the base medium. Each set of subunits equaling one half of each base unit and color-coded in a color shade corresponding to the color of the base unit. An elongated element is provided to receive the base medium.

Abstract: A teaching aid is disclosed herein that includes at least one gallon container, two half-gallon containers, four quart containers, two pint containers, and two half-pint containers. Each equivalent measurement may be attached to one another thus showing and teaching students equivalencies of each measurement in volume and capacity. A method for teaching students is also disclosed herein, using the teaching aid in conjunction with associated lesson plans and study guides.

Abstract: A method for presenting media on an electronic device. A landmark is identified based on a landmark sensor of the electronic device. Media is selected based on the landmark. The media is presented on the electronic device.

Abstract: Different types of measuring devices detachably built up with different elements are provided. The elements for forming the built-up measuring devices include suitable numbers of connecting rule elements, corner elements, swing elements, fixing bars, and fixing sleeves. The measuring devices that may be built up with the elements include but not limit to ruler, square, three-dimensional square, and arithmetic balance. These measuring devices integrate functions of many commercially available intellectual aids and can be used to take linear, area and cubic measures, practice four fundamental operations, and learn concepts about coordinates.

Abstract: A visual teaching aid adapted for the versatile teaching of various mathematical relationships, incremental scales, and other sequential and educational concepts. The teaching aid includes an elongated board, a plurality of elongated insert cards each being interchangeably mountable on the board and having numerical indicia on a face thereof, and at least two pointers that are supported for movement along the board for pointing selected indicia on the insert card and for movement relative to each other. The insert cards are removably mountable on the board without removal and replacement of auxiliary fastening means and can be used in conjunction with relatively small sized base or whole number insert cards to assist in drills of mathematical relationships.

Abstract: A teaching aid for increasing the memorization of a large number of equations comprising a front cover having a vertical column of horizontally disposed completed equations visible thereon and which front cover forms a cut out portion adjacent the vertical column and a writing sheet which is removable and positionable under the cut out portion of said front cover for providing a replaceable writing area accessible through said cut out portion.

Abstract: A visual teaching aid adapted for teaching groups of students in a classroom environment how to read rules and understand dimensional relationships. The teaching aid includes a relatively large sized elongated board adapted for horizontal wall mounting. The board has a scale along the length thereof depicting known units of length proportionally larger than the actual units and a selectively positionable pointer carried in depending fashion from a slide track mounted along the top of the board. A draw cord arrangement, which is operable from either end of the board, is adapted for moving the slide in the track to selectively position the pointer at desired locations along the scale.

Abstract: A metric block toy comprising ten blocks of varying colors, each block being a one tenth of a meter cube, and having indicia designating ten centimeter increments along one edge of each block, together with other legends designating the length of the edge invarying metric terms.

Abstract: The present invention is directed to a method and apparatus for teaching fractions to school age children. The invention provides an instrument having a base with at least two aligned scales of corresponding numerical indicia subdivided into different fractional units, as for example halves, thirds, quarters, sixths, and eighths. The base defines a space or gap between the different fractional scales so that a writing media, such as a piece of paper, may be inserted between the scales and moved either horizontally or vertically relative to one or more of the scales. The instrument provides an easy manner for a student to compare fractional units of the same integer and also to add and subtract both fractions and mixed numbers. In the preferred embodiment of the invention, the base of the instrument may be transparent so that all fractional scales are visible to the student simultaneously.

The deck comprises a plurality of suits of cards; each suit includes a plurality of cards with each card within a suit having a back side and a front side. On the front side, a relative metric prefix value indicates the value of each card. The deck comprises four suits of thirteen cards in each suit thereby facilitating use of the cards in playing traditional card games. According to one embodiment, the front of each card includes a list of the values of all cards within the suit in order and, the value of that particular card is distinguished in the list of values. The invention also includes a plurality of decks of cards which are dividable into decks having different levels of difficulty.
