I'm Dr. Joan Kang Shin, series editor of Our World, National Geographic Learning's, most popular and bestselling series for young learners of English. I'm so excited because today, I can finally share with you something that I, my co-series editor, Dr. Jodi Crandall, and the team at National Geographic Learning have been working very hard on, Our World, Second Edition. With Our World, Second Edition, we've taken everything you love about the first edition and made it even better. More real world content, readings, and photos in every level means your students will gain even more real world exposure and cross curricular knowledge than before. We've worked hard to make sure Our World's second edition brings even more of the world into your classroom. Improved grammar charts, and updated and additional grammar activities, help you strengthen your students' grammar understanding and make it easier to teach and practice grammar functions while still teaching the grammar in context. The value and mission lessons are even more beautiful and relevant than before, and even easier to integrate into your lessons. With revised activities and lesson planner support. Units and lessons now have a little extra on-page guidance to help make it easier to keep track of where you are and plan your lessons. Our World's second edition's online practice is completely new with new and improved games for practice and comprehension, workbook activities for exams and assessment preparation and a brand new learning management system, with teacher resources, class management functionality, progress reports, assignment creation tools, and messaging features. The assessment material is updated and improved for all levels. Now, with even more support for international exams. The professional development program is refreshed and updated, covering new topics, relevant to the young learner teacher. And so much more that I can't possibly tell you here. If you'd like to learn or see more, just speak to your local National Geographic Learning representative or visit ELTNGL.com/ourworld I am so proud of the work we've done with Our World, and so thankful for you and all the schools around the world who enjoy using it to teach English to young learners. I hope that this new edition helps you bring even more of the world into your classroom and makes it even easier for you to motivate your students to achieve more and interact with the world in English.
