1 Grade 2 Mathematics Prince William County Pacing Guide Teacher Focus Groups have assigned a given number of days to each unit based on their experiences and knowledge of the curriculum. It is critical that teachers stay as close as possible to the pacing guidelines to ensure that all of the have been taught by the end of the school-year, and that, as children move within the Division, their mathematics instruction remains coherent. Ongoing review should occur throughout the year. Prince William County Regulation describes the organization of the instructional day. Mathematics is allotted 90 minutes in Grade 2. This should include an uninterrupted 75-minute block of time for the lesson and an additional 15-minute block to be used for classroom routines, number talks, and/or other selected review activities. These types of activities are a critical element of mathematics instruction that provide essential practice and maintenance of key concepts and skills. Teachers may find the full wording of the objectives, along with the essential knowledge and skills to be learned, in the Unit Guides and in the Curriculum Guide. These documents are available on the Math Web site at Unit Guides created by the Teacher Focus Groups provide many suggestions for resources from which to choose. should be an integral part of the development of mathematics understanding. Each day should include a brief (10-15 minute), deliberate, and carefully planned time for introduction and review of key concepts and skills. The Routines section of each unit in this Pacing Guide includes suggestions for incremental development and ongoing review and practice of concepts and skills, as appropriate at that time of the year. It is not expected that all skills are addressed every day; each teacher should determine which skills and at what level may be appropriate on any given day.
