In 2011, the government's "Bolivarian" textbooks began to use socialist learning material. According to the "Associated Press", pro-government messages were "scattered through the pages of Venezuela's textbooks". Math problems included fractions involving government food programs, English lessons included "reciting where late President Hugo Chávez was born, and learn civics by explaining why the elderly should give him thanks". The Venezuelan government released 35 million books to primary and secondary schools called the "Bicentennial Collection", which have "political content" in each book, that over 5 million children had used between 2010 and 2014.
