1. Books and Writing Instruments Choosing appropriate books and writing instruments for children is the foundation of learning. Books should have rich knowledge content suitable for the child's age and interests. Writing instruments should be made of non-toxic, harmless, and environmentally friendly materials such as non-toxic plastic and wood. In addition, it is essential to choose easy-to-hold and write pens, such as adjustable ballpoint pens or erasable pencils. 2. Electronics and Learning Devices With the development of technology, electronics and learning devices have become auxiliary tools for children's learning. When purchasing, choose devices with a large screen, high resolution, and simple operation to protect children's vision. At the same time, ensure that the device has sufficient learning resources, such as educational applications and interactive games. II. Purchasing Pencil Sharpeners Pencil sharpeners are small tools for children's daily learning. When purchasing, pay attention to the following points: 1. Safety Performance Pencil sharpeners should have protective measures to avoid injuries to children during use. For example, the blade should have a protective cover, and the operation part should have anti-slip design. 2. Applicability Choose a suitable pencil sharpener based on the child's age and needs. For example, for younger children, choose a pencil sharpener with a shorter blade or no blade. For children who often need to replace pencils, choose a pencil sharpener with a larger capacity. 3. Durability Choose a pencil sharpener with a good brand reputation and excellent material to ensure its durability. This can reduce the frequency of replacement and save parents money.
