Addition of whole numbers

One of the best ways to teach young children math is to add a "catchy" tune to go with it. I have seen this used very effectively in the kindergarten classroom that I work in. The kids see the same video over a course of a few days and they have it memorized in no time. One of the popular websites to find video material for the kids is You-Tube. There are many great song to teach kids a number of skills on there.
In the kindergarten class that I work in the teacher uses approximately a song a week to correlate to what the lesson plans will be for the week. She plays the video on the smart board and the kids love it so much that they are automatically engaged.

Another way to teach addition and subtraction to elementary children is the use of manipulative's. Manipulative's are a good technique to use because they are "hands on" activities. Children are able to learn the concept of additions and subtract (as well as other mathematics concepts) because of the use of a tangible item that they can move around to help them understand the concept of adding or subtracting item. I have seen this used well in my classroom. The teacher will discuss the concept of one more or one less and then add a few manipulative's in the activity that follows the introduction of the concept. The children are able to grasp the concept of one more and one less much more easily with the use of manipulative's. I will definitely be using these in my own classroom.

Still another way to teach addition and subtraction to elementary student is through the use of a number line. This is a good visual for students. Number lines are a good tool to use because students can see the affects of adding or subtracting numbers so they don't just see adding or subtracting as an abstract concept. I think I would use the number line method along with other methods and also with kids older than kindergarten. While I think that some kindergarteners could grasp the concept I think it is best for 1st grade and up.

Here are some fun math games online that kids are sure to love!!
