About the GoalsThis packet contains a list of goals/objectives for each cluster of content in the Common Core State Standards for Grade 6 mathematics. Cluster headings are taken directly from CCSS documents, and each cluster has 3 to 9 goals. The goals are clear and concise, in the style of typical chapter or lesson objectives. These were written by Angie Seltzer, a mathematics curriculum specialist with many years of educational publishing experience.
To view these goals online and see related materials, visit www.mathpaths.com. Goals for Grades K-8 are available as checklists, posters, signs, and in Excel Goal Tracker spreadsheets.
For many goals, sets of Multi-Match game cards are available to help students relate models to expressions. These cards can be used by students of all ability levels for review and/or remediation.
About the Review QuestionsFor each goal there are one or more review questions, usually in short-answer format. Multiple choice questions are included when a short-answer question could be ambiguous or confusing. Some questions require a drawing, a graph, or an explanation.
There are also multiple response questions (with checkboxes) because that problem type is included in new multi-state assessments. This packet contains a total of 95 review questions that provide an excellent overview of all CCSS content for Grade 6.
Using Self-AssessmentBeside the goals are item numbers of the related questions. For each goal, students should circle Yes or No to indicate whether they understand the concept.
About the Domain IconsEach domain is represented by a letter-shaped icon that includes elements to denote key content. For example, the “E” icon includes variables and the “S” icon includes a circle graph and a spinner. Domain icons provide a quick way to identify the domain or strand of content on the pages.
