All four of my kids ages 8, 6.5, 5, and 3 loved this kit. Having two of several of the activities was a fantastic way for siblings to work together while they were able to pursue what interested them most. These were developmentally appropriate for a wide variety of ages and had so much that was creative, fun, informational, and overall engaging! I love that almost all the supplies were included except for basics like scissors or glue that we had on hand. I'll be sharing about these kits with friends for sure!
