PAGE COUNTY PUBLIC SCHOOLS Sixth Grade Mathematics Pacing Guide The following chart is an outline of the PWC Sixth Grade Mathematics Curriculum organized into Units of Study. The outline provides the suggested number of days required for each Unit of Study and an approximate test date. Space on the chart is provided for each teacher to keep the actual time spent on each objective. Unit of Study tests are on CMS. The key terms for each Unit of Study are also listed, with those considered most important/encompassing for this grade level in bold. Cross content vocabulary terms that are part of the mathematics curriculum and are applied in multiple units are: analyze, compare and contrast, conclude, evaluate, explain, generalize, question (inquire), sequence, solve, summarize, and synthesize.
