西班牙采购需求：国际学校，国际K12学院，国际私立学校，独立寄宿学校，私立学校，英国学校

I'm reaching out because I'm looking for educational products suitable for my kids. I have two children: an 8-year-old and a 15-year-old, currently studying in Spain. I'd like to explore options that will support their learning and development, especially considering the different age groups and educational needs. I'm particularly interested in resources that can enhance their understanding in core subjects and also provide some fun learning experiences. If you have any recommendations or products that fit these requirements, please let me know. I'd appreciate catalogues or any additional information you can share that would help me make the right choice for my kids.
