    Understanding the base ten system is a must for students. As a math coach and an interventionist, I work with students every day who do not understand our base ten system. They have no idea, “why a teacher told them to carry a one” in addition. They are totally confused. I love the concept of unitizing, it is essential. I love showing them how everything is interrelated in counting.
