Hi Mariam,
Teaching English and social science to grade 4 and 5 students seems to be a good combination. I feel you're helping to lay the foundation for their literacy and understanding of the world. Integrating these subjects can be particularly effective; for instance, using historical fiction or stories set in different cultures can make social science more engaging while improving their reading skills. @ANA-M57fa474ed2 post the museum of Anna Frank for those interested in history https://www.annefrank.org/en/museum/web-and-digital/ and provides a virtual tour https://www.annefrank.org/en/anne-frank/secret-annex/
Keep up the great work shaping young minds!
