Studying is a battle with my son - any ideas?

My son is in 4th grade, and getting him to study feels like pulling teeth. His grades are okay for now, but I know that if he keeps this attitude, it’s going to be a problem.

Have any tips that worked for your kids? I'd love to hear them.

We tried a fixed study routine, 45 mins after school before dinner. It works a bit but most of the time I think he just zones out. It's also hard maybe right after school.

We've cut down on distractions, and brought more positive screen time with interactive games like Prodigy and Brain Racers.

It's helping, I think he likes the competition of it all.

But he's not engaged with schoolwork or studying.

Let me know if you have any advice, thanks!
