Comparison of Length, Weight, Capacity, and Numbers to 5
In the first half of this module, students identify measurable attributes of objects in terms of length, weight, and capacity. Students learn words such as small, big, short, tall, empty, full, heavy, and light so that they will have the vocabulary needed to describe objects (PK.MD.1). The comparison of length, weight, and capacity naturally leads to discussions about quantity and number. In the second half, measurement is connected to quantity as students reason if there are enough, more than, less than, or the same number of objects in a set using matching and counting strategies (PK.CC.5). Comparing concrete sets leads to comparing quantities and abstract numbers. Children will also focus on identifying first and last in quantities up to 5 and 10 in different configurations (PK.CC.6).
