This virtual learning module explores the progression of the NBT standards across grades, and how the standards require us to build students’ conceptual understanding along with their procedural skill and ﬂuency for the four operations of adding, subtracting, multiplying and dividing. Through two progressions activities, you’ll have an opportunity to more closely study the NBT standards, as well as strategies students will use to become proﬁcient with the four operations.
