This past year the first grade classes in the school I worked with were mastering place value positions. There were many games, worksheets, and other reminder methods to teach the students what each position stood for. Learning the position values provides a basic foundational skill for the rest of their lives. Estimation and value operations depend on place values.
An extra assistant that I had not learned until lately was to add numbers using expanded notation. Prior to learning this method, I was just lining the numbers on top of each other carefully making sure that the ones position lined up. The following clip guides a first time user of expanded notation through the steps and provides practice examples. This would be a resource that I would encourage a guardian to watch with their child so the guardian would be able to better understand what it is that I am asking the children to learn.
Not only is it a good idea to introduce younger children to the concept of expanded and scientific notion, it is something that can be integrated at a young age. By teaching the children to line their numbers according to position value with the 10 and supporting exponent in place, the students are exploring pre-algebraic ideas. It maybe one are that students may try to make harder than it is if they are given that opportunity. The best way to head off any potential fears the students may have is to be prepared with many differentiated versions of the concept, websites for parental involvement at home, and as many fun projects as you can think of that illustrate the main goal. It is much easier to introduce this and allow them years to perfect before they are working with more unpredictable exponent rules in high school.
