The exercise book "Math Stars, Basic Training" for the 1st grade offers a comprehensive and playful introduction to the world of mathematics. It is aimed at children who want to learn fundamental mathematical concepts. Through a variety of self-explanatory tasks, learners can work independently, whether in class, at home, or on the go. The use of concrete visual aids promotes understanding and application of what has been learned. A special highlight is the opportunity to make learning successes visible by collecting star stickers, which increases children's motivation. The owl Eulalia accompanies the learners and provides valuable tips, while integrated solutions allow for easy self-assessment. New features also include digital materials and explanatory videos that support and deepen the learning process. The book can be used independently of any teaching materials and is ideal for daily practice and self-study.
