Talk to the teachers too. Studies is a parent and teacher joint effort.

Kids at this stage really want to have fun. As M kaushal said , if you make studies fun, she may take more interest.
For eg, maths . Maths is all around us . Get her exposed to some cool mini videos for maths for children and fun games. Reward her with a big hug and treat when she completes studies.
Talk about what she is studying in class. Make it less of work and chore and more about learning
