◇ Fun and Engaging Arithmetic ◇ Arithmetic that encourages thinking through hands-on activities ◇ Arithmetic where you "see" calculations using teaching aids ◇ Arithmetic where you verify answers through experiments This is what you'll find here. This is arithmetic from the "Fami-Sen" series, which is fun and engaging, and is different from both cram schools and "school arithmetic." Moreover, the biggest feature of the "Fami-Sen" series is that by using this text, "parents can become the teachers." The texts in this series are designed so that anyone in the family can take on the role of teacher. Just study with your child, following the text. ○ The learning content is deeper than the textbooks. Parents can teach content that is more in-depth than what is studied in school. ○ Learning games are often incorporated into the text. Through games, the whole family can enjoy learning and solidify their understanding. The discussion begins with the difference between "kado" (corner) and "kaku" (angle), and then simple teaching aids are made to create various angles using those aids. Next, we consider how to express the size of an angle numerically. We use a right angle as a basis and divide it equally, but we also touch upon the number "360" and angles as conceived by ancient people. Two types of right triangles are made with origami, and the angles of each are investigated. Finally, as a summary of the learning, an angle card game and "King's Orders" (rotating the whole body to the commanded angle) are enjoyed. When using this, the parent should act as the teacher. The printouts are not bound. The text is not given all at once, but one page at a time. It is written as if the child is reading the sentences, but if they don't understand after reading it once, have them read it again, or have the parent read it in a way that is easy to understand. However, important explanations are written on the following pages, so there is no need to add explanations. Even if the understanding is shallow at that time, the plan is designed to deepen the understanding as you read on. Please proceed as is. Disclaimer: While using the "Fami-Sen" series of texts aims to improve your child's academic ability, it does not necessarily guarantee an improvement in academic ability. (Page 33)
