- 1. 8th Grade Math Curriculum Map 8th Grade Math Curriculum Map IntroductionThis document contains all mandated 2010 Arizona Mathematical Standards for 8th grade mathematics. The standards have been organized intounits and clusters. The units represent the major domain under which the identified standards fall. The cluster represents the collection of similarconcepts within the larger domain. Within these units and clusters the performance objectives have been sequenced to represent a logical progressionof the content knowledge. It is expected that all teachers follow the sequence of units and clusters as described in the following document. OrganizationApproximate TimeApproximate times are based on a 60-minute instructional session for grades 6-8. All units and clusters must be taught prior to the 2013 AIMSassessment.Essential QuestionsEssential Questions are to be posed to the students at the beginning of the cluster and revisited throughout the cluster. They are designed to facilitateconceptual development of the content and can be used as a tool for making connections, higher order thinking and inquiry. The students should beable to answer these on their own by the end of the cluster.Big IdeasBig Ideas are the essential understandings that are critical for students’ learning. These are the enduring understandings we want students to carrywith them from grade level to grade level. Answering the Essential Questions is indicative of a student mastering the Big Idea, however they are notalways synonymous. Thus, in cases that the answer to the Essential Question does not include all components of the Big Idea, the Big Idea (for teacheruse) has been provided in italics.Common MisconceptionsThese are common misunderstandings students bring to the learning process. Being aware of such misconceptions allows us to plan for them duringinstruction.Content Standards and Mathematical PracticesThis document has been organized by content standards and mathematical practices. The content standards are those that represent knowledgespecific to the mathematical standard (The five domains). The mathematical practices describe varieties of expertise that mathematics educators atall levels should seek to develop in their students. These practices rest on important “processes and proficiencies” with longstanding importance inmathematics education. The content standards and mathematical standards have been paired to represent possible combinations of content standardswith mathematical practices. As described in the Arizona state standards, the content standards are not intended to be taught in isolation; thus, thepairing of these standards provides a possible context for teaching these standards. Each time, the performance objective should be taught to adeeper level of understanding and/or should be connected to the other standards in the cluster.9/10/2012 1 Isaac Elementary School District
- 2. 8th Grade Math Curriculum MapCommon Core/Cross CurricularThe standards in the Common Core/Cross Curricular column represent possible reading, writing, math and language standards that can be reinforcedor taught through the mathematical content standards with which they are paired.PriorityWith input from grade level teachers, standards have been prioritized in two ways. The content standards have been prioritized using a three-pointscale. Essential standards represent those that are heavily weighted on state/national exams, foundational, and/or applicable in multiple contexts.Important standards are those that are applicable in many contexts and less heavily weighted on state/national exams. Useful standards are thosewith the least weight on state/national exams and are likely only useful in a specific context. This is denoted in the priority column with the codes E(essential), I (important) and U (useful). This label applies to the content standards only. The skill/process standards that are a priority for thisgrade level are highlighted in blue and are expected to be mastered at this grade level.Key VocabularyThe key vocabulary that should be taught for each of the performance objectives is listed under key vocabulary. These vocabulary words are codedas tier one (1), tier two (2) or tier three (3). Tier one words are those that are very common and should not be explicitly taught. Tier two words arehigh utility words that can be used across content areas or contexts. Tier three words are content specific words.ResourcesThe two types of resources listed are the Web Resources resources and the Core Resources. All are suggestions that teachers may use to supportinstruction. They are aligned to the standards listed in the same row. The web resources are useful Internet links that can be used for the teacher’sedification prior to instruction or as a tool during instruction. The core resources are suggested pages from the adopted texts.Unit/Cluster ProjectThe Unit/Cluster Projects are possible projects that teachers can use to support students in making connections, critical thinking, higher order thinking,and/or spiraling curriculum. Unit projects support standards from all clusters within a unit while cluster project support the standards in a particularcluster. While it is not required that a teacher do a project with every unit or cluster these resources will support project-based instruction andpractice should the teacher choose to implement them.AssessmentThe assessment section of the map has been left blank for teachers to plan the dates that they will give a formative assessment for the cluster. It isexpected that each cluster be assessed using a common formative assessment.OtherStandards may appear more than once. Each time they should be taught within the context of the cluster and/or revisited to a deeper level ofknowledge. Underlined segments of a standard indicate an additional piece of the standard that was likely not covered in previous clusters.[Brackets] will occasionally appear though out the document and indicate clarification of the Standard. Bracketed information is not a part of thestandard itself.9/10/2012 2 Isaac Elementary School District

The types of angle relationships are vertical, complementary, supplementary, alternate interior, alternate exterior, corresponding. How can you use angle relationships to solve real world problems? Once you have one or more pieces of information about an angle relationship, you can deduce an unknown angle measure.9/10/2012 30 Isaac Elementary School District

The more trial an experiment conducts the closer the experimental probability and the theoretical probabily become. Probability ranges from 0 to 1 or impossible to certain. Probability can be expressed as a decimal, percent, or a fraction. What is the difference between a permutation and a combinations? If the order of an arrangement matters, it is a permutation. If the order of an arraggement does not matter it is a combination. In other words, a permutation is an ordered combination.9/10/2012 32 Isaac Elementary School District
