I have been using the educational materials from coreknowledge.org for a while now, and I must say, they are top-notch. The resources are well-designed, informative, and cover a wide range of subjects. The best part is that they are constantly updating and adding new content, ensuring that the materials are always relevant and up-to-date. My students have shown significant improvement since we started using Core Knowledge Foundation's resources. I highly recommend them to all educators!
