Review: This site is designed to help children practice writing numbers in expanded and standard forms. First you will see a brief description of how expanded form works. Scroll down and there is a box for practicing. You must push start. Then, the computer will give you three digit numbers written in expanded form. The child needs to write the number in standard form and push enter. I have noticed as a teacher, that some kids have a tough time grasping this concept. I think that if your child falls into that category, this would be excellent practice. It gives some easier and some tougher problems to help them practice on all kinds of numbers. The down side is that I did not find a place to practice going the other direction (turning standard form into expanded form.)
