Abstract
Abstract A numbers teaching aid particularly useful in teaching single digit numbers to children. The teaching aid comprises a series of flip cards in which each flip card illustrates a number in the number sequence of 0-10, and a plurality of beads equal in number to the highest flip card number. The beads are aligned on a rod in an unchangeable sequence, and are slidable on that rod relative one to another between a storage position and a number equivalent position. The numbers on the flip cards are colored different colors, and the beads are likewise colored different colors, the color of each bead in the number equivalent position being the same as the color of that flip card number to which that bead is an equivalent.

A numbers teaching aid for teaching the significance of numbers, said aid comprising, a series of flip cards positioned in a set and unchangeable sequence, each card having single digit indicia only thereon, said flip cards being arranged in numerical order as determined by the single digit indicia, and the color of each digit being different from the color of every other digit, and a plurality of beads positioned in a set and unchangeable sequence, the number of beads being equal in number to the number of flip cards if no flip card is provided with the digit 0 and equal in number to the number of flip cards minus one if one of the flip cards is provided with the digit 0, the color of each bead being different from the color of every other bead, the color sequence of said beads being the same as the color sequence of said digits, and said beads being movable from a storage position into a number equivalent position where the color of the last bead moved to the number equivalent position from the storage position will be the same as the color of that number on an exposed flip card where the number of beads so moved is equal to the digit on the flip card.
