As a mathematical device, the infinity sign was first discovered in 1655 by John Wallis, but its significance as a religious symbol is much older. The infinity sign has its origins in the Arabic numerals that actually came from India in the first place.
Unifix cubes are the basic block for any classroom. They are made of plastic and connect to each other on two opposing sides. They can be used to teach almost all math concept areas, ranging from one-to-one correspondence, patterns and basic number operations to fractions, multi-base projects and beginning algebra. Since students can separate unifix cubes into single units, the level of abstraction of these manipulatives is very low.
