Paper clip
A paper clip (or sometimes paperclip) is an instrument used to hold sheets of paper together, usually made of steel wire bent to a looped shape.
 Most paper clips are variations of the "Gem" type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire.
 Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper.
 When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together. Day After Reading

Singapore math (or Singapore maths in British English) is a teaching method based on the national mathematics curriculum used for kindergarten through sixth grade in Singapore.
 The term was coined in the United States to describe an approach originally developed in Singapore to teach students to learn and master fewer mathematical concepts at greater detail as well as having them learn these concepts using a three-step learning process: concrete, pictorial, and abstract.
 In the concrete step, students engage in hands-on learning experiences using concrete objects such as chips, dice, or paper clips.
 This is followed by drawing pictorial representations of mathematical concepts.
 Students then solve mathematical problems in an abstract way by using numbers and symbols. Highrise (documentary)
