The article discusses the hands project which aims to find at least three different types of functions that model lines or curves of their hands. It presents detailed discussion on how to introduce the activity as well as tips for teacher's notes and hints in implementing the activity. Moreover, the questionnaire concerning the activity is also mentioned.

This article discusses various issues related to the law of sine and Benjamin Banneker, a self-taught mathematician, surveyor, and astronomer from Guinea. Banneker was taught how to read and write by his grandmother. Banneker learned learnt mathematics as far as double-position as well as surveying and astronomy from books he had been lent by his teacher and neighbors. He began publishing annual almanacs containing his astronomical observations and predictions. He kept his notes in journals, but only one of the journals is preserved. This journal served as his notebook for astronomical observations his diary, and his mathematics notebook. The article further elaborates the features of mathematical thinking of Banneker, and its significance for students.

The article presents a mathematical-model based technique to estimate the number of votes that a presidential candidate requires to be elected as the president of the United States. The difference in the electoral votes and popular votes influencing the election of the candidate has been highlighted through the election of U.S. president George W. Bush over Al Gore in the 2000 U.S. presidential elections because Bush received more electoral votes than Gore although he got lesser popular votes than Gore. The Consortium for Mathematics and Its Applications features such problems in its High School Mathematical Contest in Modeling.
