What are the safety standards for selecting large-sized building blocks for kindergarten use?

How many large building blocks should each class have? how to calculate the quantity configuration?
There is no national unified standard for kindergarten building block configuration, but you can refer to the following experience framework and make adjustments based on the number of students in the class, the area of the activity area, and the frequency of the course.
Configuration based on class size
| Class type | Recommended number of people | Number of basic particles | Baseboard/building block table | Special components | Estimated budget range |
|---|---|---|---|---|---|
| Small class (2-3 years old) | 20-25 people | 800-1200 capsules | 2-3 base plates | Small quantity of pipes/animal accessories | Subject to real-time quotation |
| Middle class (3-4 years old) | 25-30 people | 1200-1600 capsules | 3-4 base plates | Pipe + gear assembly | Subject to real-time quotation |
| Senior class (4-6 years old) | 30-35 people | 1600-2400 capsules | 4-6 base plates | Building block wall + theme set | Subject to real-time quotation |
Configuration logic description
average capsules per person: we recommend a baseline of 40-80 capsules per person.For smaller classes, set the minimum order quantity (to avoid disputes and storage issues). for larger classes, set the maximum order quantity (to support collaborative building and themed creations). baseboard ratio: we recommend one standard baseboard (32x24 or 24x24 studs) for every 5-8 children, ensuring ample workspace for simultaneous use. replacement cycle: for large building blocks, the normal loss rate is approximately 5%-10% per semester (due to loss, chewing, stepping on, or deformation). we recommend taking an inventory at the end of each semester and replenishing stock based on the loss rate.

What other issues are easy to ignore before purchasing?
Q: can large-sized building blocks be mixed with small-sized building blocks? A: no.The large and small particle connectors have different jack sizes and are not compatible for interlocking.For kindergarten-aged children (2-6 years old), large-sized building blocks should be used uniformly to prevent the risk of accidental swallowing caused by small pieces.Wange produces both large and small particle product lines. when purchasing, please pay attention to the "large particle" designation in the product title to differentiate between them.
Q: can wange's large-sized building blocks be exported? A: wange supports oem/odm/obm. while some products are marked as "not for export: no," we also offer products specifically for cross-border e-commerce sellers.For export orders, you need to confirm the toy security standards of the target market (such as eu en71 and us astm f963), and specify the testing responsibilities and cost bearers in the contract.
Q: are the baseplates for building block walls and regular tabletop building blocks interchangeable? A: the bottom plates of wange's building blocks wall (such as 811595652171, 24×17capsules) and the bottom plates of the desktop (such as 811628696598, 32×24capsules) have different sizes. the capsules grids are compatible but the installation methods are different.The building block wall requires wall fixing accessories, and the desktop bottom board can be placed directly.Before purchasing, please confirm the intended use to avoid ordering the wrong specifications.
q: what is the minimum order quantity? can i restock in small batches? A: on 1688, wangge generally lists its large-sized products with a minimum order quantity (moq) of just 1 piece, supporting small-batch replenishment.However, the price advantage of bulk purchasing is usually reflected in a certain quantity or more. it is recommended to confirm the ladder price grids through inquiries.
