Practicing addition with your child is a great way to get him excited about math! Young kids who are beginning to learn addition often need to see a visual representaion of any given problem. Many kids will use their fingers and toes, but make things more fun by using counters. You can use pieces of cereal, beads, mini marshmallows or anything you would like. Kids love switching things up with large-sized counters, so bust out pillows or purses to make learning addition even more fun.
In fact, if you successfully learn a few algebra concepts then you will want to have more. Practice is really important in algebra and you ca not expect to learn everything from online courses or tutorials. You need to go through the concepts and the principles of algebra again and again in order to learn them.
