K-12 MATHEMATICS STANDARDS

Transcription

1 MATHEMATICS To the reader: This document presents our mathematics standards through the lens of Understanding by Design. We began by identifying the important broad understandings and the essential questions for mathematics. These particular understandings and questions allow us to answer the major question: What are the most significant ideas that we want all students to appreciate after completing the study of mathematics in the Sharon school system? We also determined the broad understandings for number sense, algebra and geometry. After that, we worked on the knowledge and skills that students K-12 need to learn. For many, this change in emphasis on the understandings of mathematics, rather than on memorizing steps is new. However, with depth of understanding, students will be more able to apply what they learn to new situations - which is truly the essential goal of education. We will revisit this document as we use it in our classrooms and consider modifications. Two appendices occur at the end of the document. The first appendix indicates the materials that are used in the K-5 classrooms for our Everyday Mathematics program. The second appendix indicates the vocabulary and important phrases that students are expected to learn in grades K-8. K-12 MATHEMATICS STANDARDS The following list of standards represents the major understandings and questions that underlie all classes in mathematics. We would like you to keep these in mind throughout your reading because they are an important part of each grade. Problem solving, making connections, estimation, patterns, and appropriate use of technology are essential ingredients throughout our program. Through modeling events in the real world, mathematics is the foundation for many aspects of society. How do we use each type of mathematics to model situations in the real world? How do we create, test and validate a model? What mathematics can be used to obtain a desired product or outcome? What models produce the best solutions for a given problem? What are the benefits & limitations of modeling situations? Successful problem solving involves flexible thinking, asking questions and taking risks. Additionally, a variety of problem solving strategies may be used to arrive at appropriate solutions. What are the most appropriate problem solving strategies for a given situation? How are visual and physical models of a mathematical idea helpful for representing concepts and solving problems?

2 What information is relevant or superfluous? Is estimation more appropriate than finding an exact answer? Is the proposed solution reasonable? Patterns & relationships can be used to represent information, interpret data and make predictions. What patterns or relationships do we see in each type of mathematics? What are the different ways to represent the patterns or relationships? What different interpretations can be obtained from a particular pattern or relationship? What predictions can the patterns or relationships support? How can we use or test our predictions? Are they valid? Are they significant? Mathematics is a language for communicating ideas. How do we translate verbal ideas to the language of mathematics? How do we translate the mathematics into English? What are the different ways of communicating mathematics with clarity? What is the most appropriate way of communicating a mathematical idea in a particular situation? Connections exist between current learning and prior understanding. Also, connections can be made to various strands of mathematics, as well as to other disciplines. What previous learning helps us to understand the new material? How does what we are learning relate to other areas of mathematics? How does what we are learning relate to other disciplines? Properties, postulates and theorems form a foundation for the structure of mathematics. Where did the properties, postulates and theorems originate? How did the properties, postulates and theorems originate? Who were some of the people responsible for developing the different theories of mathematics? Why is a universally accepted set of properties, postulates and theorems essential?

3 How are the properties, postulates and theorems used in mathematics? Technology and other resources can be used to support mathematical investigations. What technological tools or other resources are available? Which tool(s) is (are) most effective in a particular situation? How do we determine the reasonableness of technological results? When is it appropriate to use technology GRADE 12 COURSE: CALCULUS The understandings, knowledge and skills gained through the algebra, geometry and precalculus courses continue to be needed throughout calculus. In the college preparatory calculus, some minimal review of skills, functions and their graphs will occur. However, students in the advanced placement classes will be expected to be able to recall their prior mathematics without this review. Students in the AP classes will also be required to complete problems equivalent to those on the AP exams. *AB & BC do these topics in addition to what is expected of the standard classes **BC only Understanding The concept of a limit is the foundation for calculus What is meant by the concept of a limit?
