Mix it up a little.
For some kids, studying is tough because they need to learn material in different ways. If your child is having a hard time with a writing assignment, help him talk it through or act it out first. Use vocabulary words in everyday conversation—even if you have to be silly about it.
For math, use household items to help him figure out problems. Teach fractions with slices of pizza, for example. And help your child learn spelling words by letting him text them to you. You can even help him master new facts by setting them to music!
