Here is a great resource to help you reinforce what you are teaching in math. SoftSchools.com is chock full of fun math games and math worksheets. They also breaks the games down into categories by grade. Here I will hightlight just a few that we've enjoyed.
Remember, depending on the curriculum you are using, some games may be too advanced (even if they are a grade or two lower) and others in a particular grade may be too advanced. I don't know how they have determined their grade categories. So be sure to check out the game before your child to be sure they have learned the skills, this will help you avoid frustration or discouragement.
