Cluster 7

Students build a foundational understanding of the base-ten number system by creating teen numbers composed of ten ones and some more ones. This work extends and formalizes all their experiences composing, decomposing, and naming quantities throughout the year. Through various experiences students have developed a deep understanding of the relationships that exist between and among numbers 0-5. By the end of the year students will be able to accurately, efficiently, and flexibly compose and decompose numbers 0-5 with automaticity. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
