A device for teaching counting binary numbers (base 2) includes a frame having a plurality grooves with sliders deployed within said grooves. The device bears a plurality of zero indicia, each indicia aligned with one of the grooves. Extending from the slider is a label “1” which overlays the corresponding zero indicia when the slider is moved to a first end of the groove to indicate that its value is operative. Each of the sliders are labelled in binary progression (1, 2, 4, 8, 16, etc.). In use, the device can teach the 0's and 1's representation of a decimal base number by correlating the visible 0's and 1's on the device with the sum of the numbers displayed on the sliders. In addition to decimal numbers, the device may also be used to convert binary numbers into hexadecimal numbers and other base systems, and to convert binary numbers into text.

A method of using a math manipulative configured to help a user organize a breakdown of a given number into its prime factors, the method including using a board comprising columns, each column assigned to a different prime number and configured to accommodate chips, the board giving a visual picture of the prime factors of the given number to the user, and adding the chips in each of the columns by the user, wherein a number of chip added in each of the columns is the number of times the prime number corresponding to each column is a prime factor of the given number.

A teaching aid for binary programming language contains: a Rubik's cube including six surfaces. Each side has fourth corner pieces, four side pieces, and a center piece which are rotatable. Each of the four side pieces is defined among any two adjacent corner pieces and the center piece, and the center piece is defined among the four corner pieces and the four side pieces. The center piece has a calculation sign, and each of the fourth corner pieces and the four side pieces has a binary number.

A lever system teaching tool includes a frame and an elongate member that is releasably coupled to the frame. The elongate member defines a plurality of mounting stations along its length. The elongate member can be pivotally or rotatably coupled to the fulcrum of the frame at any of the mounting stations. The elongate member includes repositories at opposite ends of the elongate member. The repositories are sized and shaped to retain one or more incremental loads.

An information processing method includes causing an electronic apparatus to display an arithmetic setting frame in a screen of a display of the electronic apparatus. The method further includes causing the electronic apparatus to send, to outside of the electronic apparatus, mathematical expression data on a mathematical expression formed in the arithmetic setting frame by at least a part of coordinate icons being selected by a user operation. The method further includes executing an arithmetic operation based on the mathematical expression data sent from the electronic apparatus, and sending, to the electronic apparatus, arithmetic result data of the mathematical expression as a result of the arithmetic operation. The method further includes causing the electronic apparatus to display an arithmetic result of the mathematical expression based on the arithmetic result data in the screen.

Systems and methods to define a scenario of conditions comprising the steps of defining at least one condition for at least one educational objective, the at least one condition being represented by a constraint and scheduling the conditions into a scenario of conditions. In some embodiments, the scheduling is performed by analyzing the constraints using constraint programming. In some embodiments, the constraints comprise mathematical or computational constraints representing a range of variables. Also disclosed are systems and methods to monitor a scenario of conditions.

Disclosed is a digital pen that tracks the user's writing and provides useful feedback based on the user's writing. In one embodiment, the pen may provide feedback when the user has written a misspelled word, invalid mathematical expression, or any noncompliant expression. The pen may also provide feedback relating to the user's handwriting. The feedback may be visual, auditory, or tactile, and may be realtime or delayed. Statistics relating to the user's performance may be tracked, uploaded to external devices, and shared with others. This allows the user and interested parties to track the user's progress over time. The disclosed pen will be useful in educational settings.
