When my son was a young boy and doing his first study time and he seemed bored, I told him to take 20 minute breaks and do what he wanted and he did;he played 20 minutes of basketball in our finished basement where he was studying. It broke his boredom during his study time. Other things that my son did during his breaks was kicked a soccer ball, played plastic tipped darts, Art with me, and played his instruments.
I recommend that you inform your child about taking 20 minute breaks between their study and explore with them their favorite activities.
I hope that All have a Very Happy and Healthy New Year!
