Here are some grammar exercises for your child to complete. There are two sets. The Grammar 1 is a little easier, and Grammar 2 a bit more challenging. Choose the exercises which you think suits your child's ability. You could always start with the easier ones, and move on to the more difficult work when they become more confident.
Don't worry if you can't print the sheets out. Just use the worksheets on the screen, and your child can complete the tasks on paper.
