For over 40 years now, UNESCO has been celebrating International Literacy Day by reminding the international community that literacy is a human right and the foundation of all learning. The theme of the 2017 day was Literacy in a digital world. You can download a poster from the Unesco website. For further information visit the UN's International Literacy Day and the UNESCO Literacy Programme websites. The issue of literacy is a key component of the UN's Sustainable Development Goals and the UN's 2030 Agenda for Sustainable Development. One of the targets of Sustainable Development Goal 4 is ensuring all young people achieve literacy and numeracy and that adults who lack these skills are given the opportunity to acquire them. There is a useful 'infographic' showing facts about world literacy and why it is important - download as PDF from UNESCO website. There are also resources and activity kits available on the International Literacy Association website. The United Nations Association – UK (UNA-UK) has a page with background information and teaching activities for International Literacy Day. For additional ideas to help you mark International Literacy Day, browse through the teaching resources listed on the Global Dimension database under the topic 'Education'. You can also find resources relevant to SDG 4 in the World's Largest Lesson section.
