Unit 2 is typically an eight-week unit taught from November to January.
Measurement is an area of mathematics that is used in many aspects of everyday life. The study of measurement concepts provides opportunities for making connections to other mathematical concepts. For example, experiences with measurement can help students develop their understanding of number and operations. Likewise, students apply concepts of number to facilitate processes of measurement.
The big ideas in the primary grades for developing the process of measuring are: recognizing that objects have measurable attributes, making comparisons, selecting a measurable attribute, choosing an appropriate unit of measurement, and determining the number of units. Experiences should include opportunities to use measurement in a variety of ways.
Students also extend their understanding of addition and subtraction concepts in the unit. Students should have opportunities to model addition and subtracting concepts using concrete objects. Modeling will help students to develop an understanding that the sum of two numbers is the same regardless of the order in which they are added. Students also see that addition models can be used for subtraction. This knowledge is essential for developing mastery of basic fact families and provides a foundation for future work with computation.
