This is a set of Benesse's Kodomo Challenge educational materials. Thanks to these materials, my child enjoyed learning about language, communication, numbers, shapes, and more. These materials are for children aged 2-4, but they can be enjoyed for a long time afterward. I will include any other items that seem like they can be included in addition to what's pictured. The coaster making set, building blocks, and the course set have most of the parts for two people, so you can play more dynamically than usual. (Some parts are missing, so not everything is for two people.) - Books, DVDs (including main materials and trial DVDs) - Word play and shopping set - Coaster making (make courses using mechanisms) - Building blocks - Course set - Donut set - Card game - Hiragana tracing - Robot assembly The books weren't used much, but since they were used by a toddler, some may be torn or wrinkled, but they can still be read without any problems. The Hiragana tracing set also shows signs of use, so please be aware of that. Thank you for looking.
