Introducing the H5 masterpiece titled 'Sun Qichen' created using the online design platform Eqxiu.com. This educational piece focuses on Montessori mathematics and sensory training, designed to assist children in learning the recognition of numbers 1-9, their corresponding pairings, and the relationship between numbers and quantities. The H5 also introduces the concept of number 10, the use of red and blue number rods for 1-10, and the counting of numbers up to 100 with the help of sand tray practice. For the summer break, the H5 encourages home-based activities using toys like Lego blocks and watercolor pens for quantity practice and recognition of numbers 1-10. Family members can engage in number games and create sand trays with rice and plates for at-home practice. Additionally, the H5 covers Montessori sensory education with the learning of the four groups of cylinder blocks to perceive sizes and textures, the recognition of primary colors, and an introduction to color classification. It also teaches the basics of cool and warm tones. The H5 is an excellent tool for parents and children to engage in educational activities at home, promoting sensory development and mathematical skills.
