A mathematics teaching aid kit comprises a storage box, teachers manual, task cards, and manipulative components used to teach a mathematics program. The manipulative components comprise sets of individual thin rectangular and square plates or stair members of different colors divided into separate squares forming ten distinct shapes ranging from one square to ten composite multiple squares illustrating the numbers one to ten. The reverse side of the stair members is divided identically, but of different color or surface texture. The teaching components comprise square or rectangular tile members, some with positive numbers on one side and negative numbers on the other and others with arithmetic symbols printed on one side, and a pair of thin elongated rectangular members or number line bars, one divided into evenly spaced increments bearing positive numbers, and the other having identical increments and indicating negative numbers. A square frame or place holder represents unknown numbers, and a thin rectangular pointer bar having a different color on each side and one pointed end represents directional movement.
