This publication is part of a series of teaching-learning modules developed by UNESCO and P&G Whisper India with the goal of integrating period and puberty education in school curricula. The series is structured into five modules that address key intervention areas related to MHHM, including: 1. building a curriculum that understands the biological and social impacts of puberty; 2. guiding teachers on the menstrual hygiene education curriculum; 3. providing teaching-learning materials geared towards addressing the specific needs of girls with disabilities; 4. highlighting the impact of gender inequalities on menstrual health and hygiene for both girls and boys; and 5. addressing nutritional approaches related to menstrual health and hygiene. This teaching-learning resource is designed to provide scientifically accurate content in terms of best practices and standards on MHHM from across the globe. This module creates space for critical thinking, discussion and reflection, and equips learners and facilitators with holistic information with which to start crucial conversations related to puberty and menstruation, challenge harmful ideas in and around them, and confidently support human rights for all. Ultimately, the goal of this module is to provide comprehensive, skills-based, learner-friendly MHHM education and build young people’s capacities to understand not only the biology but also the gendered nature of puberty and menstruation. Each chapter contains explanations of the subject at hand, stories, case studies, learning activities, illustrations and tables designed to provide a better understanding of the issues surrounding MHHM. A glossary is also included to ensure that you, the reader, become familiar with different terms related to menstruation.
