A game board apparatus (100) and a method of placement of tokens on the board is disclosed. The game board apparatus (100) comprises a plurality of tokens (130) with a reference image (132) at its each side, a board (110) with plurality of recesses (112) structured on the board. The recesses (112) formed on the board (110) are structured to receive the tokens on the board (110) adjacent to a token (130) already placed on the board (110) or adjacent to the boundary of the board (110) having reference images (132). The token (130) which is to be placed is identified by matching the reference image (132) on the sides of the token (130) already placed on the board (110) with the reference image (132) on the side of the token (130) which is to be placed on the board (110), thereby avoiding displacement of the token (130) on the board (110) when the board (110) is lifted. While placing a token (130) in the recess (112) at the boundary of the board (110), the token (130) which is to be placed is identified by matching reference image (132) at the boundary of the board (110) with the reference image (132) on the side of the token (130) to be placed, thereby avoiding displacement of the token (130) on the board (110) when the board (110) is lifted.

The device is a stylized board to monitor and reward children's educational and behavioral goals. The board comprises a flat surface with raised up, moving parts, where some laterally moving parts are used to track the completion or failure to complete daily goals, and the other moving parts revolve to eventually reveal a hidden image when the child achieves a particularly noteworthy success.

An improved numeracy and place-value educational device which accurately displays a range of both whole-number and decimal place-value properties. A conventional counting-wheel odometer comprising a plurality of sequentially numbered counting wheels (10a-10f) and motion transfer components (not shown) is supported by a frame (12). A decimal carrier (20) moves laterally across a portion of the frame (16). The lateral movement allows a decimal point (20) to precede or follow any numeral in a specific row displayed by the counting wheels (10a-10f). A place value band (18) displays place value names (19a-19f). Its movement, in unison with the decimal carrier (20) and a moveable comma (241, maintains the correct orientation of place-value names (19a-19f) in relation to the decimal point (20) in unalterable fashion. Force is applied to the motion transfer components which selectively rotate the counting wheels (10a-10f). A sequential, dynamic display of both whole-number and decimal place-value names, notations, and properties is presented consistently, accurately, and objectively.
