How to set the selection standards for educational institutions to purchase building blocks?

Selecting stem building blocks is not as simple as "buying a set of building blocks". it needs to match three dimensions: age group, teaching goals and classroom usage intensity.

classification by age group:

classification by usage scenario:

kindergarten daily teaching: large-sized basic building blocks + building block table base. configured according to class size, with 20-30 sets per class. early childhood education center interactive area: building block wall + large-sized basic pieces, ideal for open spaces and parent-child activities. elementary school stem curriculum: small brick military/construction series + baseplates, designed for science and technology classes and competition training.

• shopping mall/community experience class: building block wall + large capsulessuit, 5-10 sets of building block wall can support the traffic diversion activity.

The key principle for product selection is: first, determine the age range of your students and the course objectives. then, match the product line based on the size of the learning materials and the thematic focus.For children under 6, large-sized building blocks are recommended for enhanced safety. once they're over 6, you can introduce smaller-sized themed sets to increase the challenge and learning depth.

When purchasing building blocks in bulk, what qualifications and certifications must be verified?

Safety compliance is the bottom line when purchasing children's educational toys and materials.Before placing an order, educational institutions need to verify at least the following three items:

**1.3c certification (china compulsory product certification) **

Building blocks belong to the category of kids toys and must pass 3c certification before they can be sold on the market.Wange building blocks have passed 3c certification. public information shows that its 3c certification code is 2022152202041591 (visible on some product pages).When purchasing, you should ask the merchant to provide a copy of the certification report and check the certificate number, product name, scope of application and validity period.

2.Factory third-party certification

Wange factory has passed the fca certification of tuv (certification body: tuv, report number: tp1610120202).Fca certification focuses on the production capacity and quality management system of the factory, and can be used as a signal for initial screening of suppliers, but it is not equivalent to product quality certification.

3.Material and process safety

The material of wange building blocks is marked as abs plastic, which is a commonly used security material for kids toys.Recommendations for bulk purchases: -request for material testing report or msds file. Check the physical sample for smoothness of edges and corners, particle interlocking, and color consistency.

• confirm whether the packaging complies with the requirements of kids toy labeling (applicable age, warnings, etc.).

> note: the 3c certificate number and expiration date recorded in the knowledge base are from historical data, and some certificates show that they have expired.Before purchasing, be sure to ask the merchant for the original or digital copy of the current valid 3c certificate, and on the [national certification and accreditation information public service platform] (http://cx.cnca.cn/)check by yourself.

step 1: get sample for verification

Minimum order quantity of 1 piece for wange single products, perfect for testing the waters with smaller, initial batches.When taking samples, focus on verifying:

• the bite of the capsules and the feel of the assembly (too loose and easy to fall apart, too tight and difficult to remove). Color accuracy and smooth edges (a must for children's product safety).
• package integrity and labeling compliance.

step 2: trial classes in small batches

Order based on the usage of 1-2 classes (20-30 sets), and verify in actual teaching:

• whether the teaching aids match the course difficulty and student age.
• whether the loss rate is within the acceptable range.
• whether the replacement parts and after-sales response are timely.
