In this Teaching Tip I provide a link to a short YouTube video. The video describes three ways in which mathematicians express numbers: word form, standard form, and expanded form. Children are expected to learn these various forms as part of their study of place value, yet they frequently confuse the meanings of these forms. The video features three movements that you can use to help kids understand the difference between word form, standard form, and expanded form. Using movement to learn and remember academic content is always something that I strongly recommend. Give this idea a try in class with your students or at home with your children.
