Common Core State Standards

522 Words3 Pages

The Common Core state standard used through this learning segment is 8.EE.A.4: Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology. For this learning segment, we will only be covering the first part of the standard where students will be performing operations in scientific notation. This standard addresses conceptual understanding because students must understand the meaning of scientific notation in order to perform operations …show more content…

It also addresses procedural fluency in that students, with conceptual understanding, will “perform operations,” building on the arithmetic skills they already have with their procedural fluency of exponent laws. Students will use problem-solving skills when they must decipher context to find relevant information in order to perform operations in scientific notation. The lesson 1 learning objective, “given a very large or small number, scholars will be able to write an expression equal to it using a power of 10 and identify whether or not a number is written in scientific notation,” will address conceptual understanding and mathematical reasoning as students make a connection between powers of 10 and their prior knowledge of place value, understanding that the power of 10 has meaning. Students must then use mathematical reasoning to judge how large or small a power of 10 is. In this comparison, they will show conceptual understanding on the meaning of exponents as repeated multiplication. Procedural fluency will be addressed in students being able to recognize that a number is correctly written in scientific notation and being able to

    Reading this question, I experienced a high level of mathematics anxiety, I realised I could solve this question however I hesitated. I was contemplating ‘how I was going to communicate and explain my thinking?’ Initially to solve this question I utilised ‘the order of operations’, this is a knowledge I previously developed and indicates ‘multiplication and division are always completed before addition and subtraction’ in mathematics. I referred to a text book to extend my understanding, and according to Van de Walle (2010), ‘the power of two’ is an exponent which in this question is merely a shorthand interpretation for repeated multiplication of a number, times by itself.

  • How Does Scratch Code Affect The Ability Of Fourth Grade Math Students?

    182 Words  | 1 Pages

    My research will study the impact of coding on the ability of fourth graders to recall multiplication facts. The question I will answer is, How does Scratch code impact multiplication fact automaticity in fourth grade math students? I will determine whether the use of Scratch coding can increase the ability of fourth grade students to recall basic multiplication facts within a specific time period. To do so I will have students complete a timed assessment of 50 basic multiplication facts between 0 and 9. I will also study student comfort levels with learning math, and in particular recalling multiplication facts.

    It was discovered that in education there were certain areas that were universal and common among learning. The two main subjects of concern were English language arts and mathematics. Common core is the new curriculum implemented now in school systems to develop learning. Common Core Standards are a clear set of shared goals and expectations for the knowledge and skills students need in English language arts and mathematics at each grade level so they can be prepared to succeed in college, career, and life. Although, Common Core seems to be here to stay this article addresses concerns in reference to content, instruction, and assessment.

    In February of 2015, the state of Georgia revised the Common Core Georgia Performance Standards and renamed them the Georgia Standards of Excellence ("Georgia Standards of Excellence (GSE)," 2015). Georgia’s transition from Common Core to GSE created instructional shifts. One of the areas affected by the shift is in the area of English Language Arts. More specifically, the role of the principal has shifted from an overall manager to that of instructional leader. In addition, principals now more than ever are being held accountable for student learning.

Some students have problem with it when they think about repeated addition and repeated multiplication. If I teach the basic rules of exponents, students will understand the difference between the multiplication and exponents. The other problem students mostly have trouble with in exponents is variables. Students need to understand the basics of solving exponential equation with variables.

    Throughout the lesson different techniques were practiced and certain mathematical concepts involving exponential functions were taught to an Algebra I class, consisting of nine students. As a student teacher, I was able to recognize the students level of comprehension by asking them probing questions during the lesson. In the classroom, the concept was taught by gradually increasing the comprehension level of the lesson. Programs such as Demos, Geogebra were used throughout the lesson by the student teacher to reinforce the ideas with a visual graph. The student teacher, Mee-Lai also encouraged students to be able to use their Inspire calculator which helped them check their answers.

  • Why Is It Important To Use MN Academic Standards For Mathematics

    351 Words  | 2 Pages

    There are many reasons why it is important to use the MN Academic Standards for Mathematics when designing units and lessons. The first reason why units/lessons should utilize state standards is that the standards can assist teachers when organizing instruction throughout the school year and across grade levels as state standards outline what key ideas are necessary to be taught and also provide the sequence and/or order in which those concepts should be taught. Understanding these standards help prevent students’ from not learning a concept because of the assumptions that teachers’ may make about what students’ have already learned it or will they should learn it in higher grades. Ultimately, the students’ doesn’t learn the specific topic

    The newest push in American education is a nationalized curriculum, otherwise known as Common Core. It has been adopted in 46 states and the District of Columbia, and implementation will begin in the fall of 2014 (Ravich “Why”). Common Core makes widespread changes to math and language standards, as well as reading content. One of the major changes national educational experts have made is regarding the types of texts students read. Common Core places a greater emphasis on informational texts rather than fictional text.

  • Manipulatives Are Beneficial To Student Learning

    271 Words  | 2 Pages

    The final way that manipulatives are beneficial to student learning is that they help students to communicate their understanding of concepts in an easy to understand and universal way. Manipulatives help students to “communicate their mathematical thinking”, even when words evade them (p. 78 NCTM). Sometimes students struggle to put their mathematical thinking into words, but with the use of manipulatives they can show their thinking and working through the manipulatives can help them to verbalize their thinking. Manipulatives help to break down concepts into their most simplistic forms, which allows the students to gain the fundamentals they need in that area of learning in order to succeed and be able to explain more complex concepts later

    Something that is new to me is that in Kentucky Core Academic Standards there is school expectations in it. An example is that a school must increase student attendance rate and reduce physical and mental health barriers to learning. Something that I read that surprised me was that the KY Core Academic Standards is only an outline of the minimum content standards required for all students before graduating from a public high school in Kentucky. I believed that the KY Core Academic Standards expressed all required content standards that students must know before graduating. In the KY Core Academic Standards, it explains how it helps to ensure that all students are being provided with common content and receive the same opportunities to learn.
