That is really an answer only you will know mama. 🙂 We did Learning About Birds last year and I considered my 3rd grader a younger child. However, not all 3rd graders are the same. So, take a look at the assignments and decide if she is ready for more. The goal is to challenge but not frustrate. You could always select assignments assigned to older children and go deeper with her if the interest is there and you think she could do it. Btw…. I LOVE Learning About Birds! All of our kids, ages 6 – 11 enjoyed it so much. I am amazed at both their knowledge and interest in birds. They are now able to identify so many birds. And they still call every crow Blacky. 🙂
