See campaign details (Transitions to Z-kai website) Campaign Overview Z-kai Correspondence Education preschool course (for 3-year-olds, 4-year-olds, and 5-year-olds) values fostering children's proactive attitude towards learning, known as 'Atonobiryoku' (growth potential). In the 2026 academic year, the preschool course has been renewed. It now supports 'creating an environment full of learning' with even more enhanced teaching materials and items. Currently, all those who request materials for the preschool course will receive a free 'Trial Material' to experience the actual teaching materials, along with limited-time worksheets tailored to their child's age and 'Number Play Cards' that parents and children can enjoy together. Please take this opportunity to experience Z-kai's teaching materials. Introducing Limited-Time Gifts ● Limited-Time Worksheets (for 3-year-olds, 4-year-olds, and 5-year-olds) Carefully selected problems from Z-kai preschool course's popular 'Kangaeru Chikara Work' (Thinking Power Work) that children can tackle now. The content is designed for parents and children to enjoy together, drawing out 'I understood!' and 'Thinking is fun!' and helping children develop a positive attitude towards learning. It's also an ideal first step for children starting worksheets. ● Number Play Cards (common for all ages) [Until June 30] Parents and children can play against each other using the cards. Children can become familiar with numbers while having fun. The back of the included battle sheet introduces four ways to play. Perfect for parent-child time at home. ● Also delivering 'Trial Materials' for the preschool course You can try both the work materials and experiential learning materials that will actually be delivered upon enrollment. Samples of submission assignments are also provided, and picture book-style materials are included for 3-year-olds. The age-specific worksheets will be presented to those who apply by August 31, 2026 (Monday), and the 'Number Play Cards' to those who apply by June 30, 2026 (Tuesday). Now that the new school year has settled down a bit, if you are considering your child's learning, please take this opportunity to request materials.
