This is a set of educational materials perfect for children entering first grade next year or currently in first grade, including a 4-DVD set and a learning clock. The map of Japan is for students in grades 2-4. This set teaches basic arithmetic, telling time, hiragana, and the map of Japan in an easy-to-understand way. DVD playback and viewing have been confirmed. We have watched these several times when our child was in kindergarten and first grade, so please understand that these are used items before purchasing. 【4-DVD Set】 ① DVD: Let's Learn the Japanese Alphabet! ② DVD: Let's Learn 1+1! ③ DVD: Let's Learn to Tell Time! ④ DVD: Let's Learn the Map of Japan! (Targeted for grades 2-4) - Number of DVDs: 4-disc set 【Excellent Tamaishiki Learning Clock】 This is a learning clock given at a cram school. Not for sale. You can only get it by attending a cram school event. After entering elementary school, children begin to study time in school, so we purchased this as an elementary school learning material. Unlike school materials and commercially available learning clocks, when you move the long hand, the short hand also moves along with it, allowing children to feel the movement of the clock more realistically. Specifically, if you move only the long hand as you would with a regular clock, the short hand will naturally move, and you will be able to read the time down to the minute without having to adjust or move it. This is for first-grade learning, but it's a very good clock, so you might want to keep it for learning for a long time. We have two, so we are offering one for sale. Thank you for looking. Please contact us if you have any questions.
