Assessing Conceptual Understanding of Rational Numbers and Constructing a Model of the Interrelated Skills and Concepts
Students continue to struggle to understand rational numbers. We need a system for identifying students’ strengths and weaknesses dealing with rational numbers in order to jump the hurdles that impede instruction. We need a model for describing learning behavior related to rational numbers – prerequisite skills and development of rational number sense – that is dynamic and allows for continuous growth and change. It would inform us of the important background knowledge that students bring with them and the prior experiences that influence their level of understanding. It would further enable us to assess students’

What is being suggested is to bring it all together in a practical way. Briefly highlighting various assessments and reports that have identified and highlighted the importance of conceptual understanding enables one to trace back to the “hatching” of the idea. In addition, outlining the course that got us to where we are today, trying to determine what it means to understand something and how understanding can be assessed assists us in continuing that course of action in the right direction.
In 1980, recommendations were made by the National Council of Teachers of Mathematics for reforming mathematics instruction in An Agenda for Action. These recommendations were based on results of the second National Assessment of Educational Progress (NAEP) and on data collected by the National Science Foundation (NSF) largely from a study called “Priorities in School Mathematics” (PRISM). Specifically in the area of fractions, NAEP contended that students’ inability to compute with fractions was the result of dependence on rote memorization of algorithms and a focus strictly on routine problems. Among eight recommendations, An Agenda for Action called for problem solving to be the focus of school mathematics in the 80’s and basic skills in mathematics to be more than computational fluency. The fourth NAEP showed improvement, but indicated that mathematics instruction still lacked depth,
This paper will demonstrate the pre-service teachers’ understanding of mathematical practices as part of the Common Core State Standards in Mathematics. It will address two specific standards for Mathematical Practices, describing the essence of both and providing a description of how teachers facilitate these practices and how students are engaged in the practices.
Algebra is a critical aspect of mathematics which provides the means to calculate unknown values. According to Bednarz, Kieran and Lee (as cited in Chick & Harris, 2007), there are three basic concepts of simple algebra: the generalisation of patterns, the understanding of numerical laws and functional situations. The understanding of these concepts by children will have an enormous bearing on their future mathematical capacity. However, conveying these algebraic concepts to children can be difficult due to the abstract symbolic nature of the math that will initially be foreign to the children. Furthermore, each child’s ability to recall learned numerical laws is vital to their proficiency in problem solving and mathematical confidence. It is obvious that teaching algebra is not a simple task. Therefore, the importance of quality early exposure to fundamental algebraic concepts is of significant importance to allow all

The aims and importance of learning provision for numeracy development are to ensure all students understand that maths is a vital part of everyday life and will continue to be used throughout their life. Primary schools will teach students to learn various methods and techniques to be able to reach the correct answer. The end goal means more students will be able to solve a mathematical problem, independently, using a method that suits them. They can then develop their learning to improve their knowledge and apply it to real life situations; such as counting in groups of numbers such as 5’s or 10’s, which in turn can be applied when paying for
Numeracy development is important for all children as maths is an important part of everyday life. The way in which maths is taught has changed greatly over the years. When I was at school we were taught one method to reach one answer. Now, particularly in early primary phase, children are taught different methods to reach an answer, which includes different methods of working out and which also develops their investigation skills. For example, by the time children reach year six, the different methods they would have been taught for addition would be number lines,
Through the Rational Number Interview I was able to gain insight into Adams mathematical understanding of fractions, decimals and percentages. As a student in year 5, Adam was able to make connections using various mathematical strategies. Adam has an understanding of infinite numbers, for example, when asked how many decimals are there between each rational number (0.1 and 0.11), he answered promptly with “many numbers”. Adam was able to acknowledge that a fraction can be shown as a division problem, “divide the pizza into fifths and each get 3 pieces”. He was able to calculate by partitioning the pizza, and by dividing each pizza into the amount of people (5). Adam shows residual thinking when building up to the whole
Similarly, the Jordan study proved a direct link between counting and focusing on strengthening number sense and increased reasoning and mathematical understanding across different forms of assessment. Most notably, the number sense group my strong and sustainable gains on story problems,
The National curriculum states that in Mathematics teachers should use every relevant subject to develop pupils’ mathematical fluency. Confidence in numeracy and other mathematical skills is
Children at this age also have different skills related to numeracy. Fostering numeracy skills in early childhood education not only predicts for later Math achievement but also for greater literacy skills (NAEYC, 2009). Since mathematical concepts are often intertwined with so many areas such as science, literacy, dramatic play, block building, and more, math learning centers offering interdisciplinary materials and activities ensure that young children grow to understand and appreciate the real life applications of mathematical concepts (Fu, 2010).
Multiplicative thinking, fractions and decimals are important aspects of mathematics required for a deep conceptual understanding. The following portfolio will discuss the key ideas of each and the strategies to enable positive teaching. It will highlight certain difficulties and misconceptions that children face and discuss resources and activities to help alleviate these. It will also acknowledge the connections between the areas of mathematics and discuss the need for succinct teaching instead of an isolated approach.
Teaching students effectively in areas of multiplicative thinking, fractions and decimals requires teachers to have a true understanding of the concepts and best ways to develop students understanding. It is also vital that teachers understand the importance of conceptual understanding and the success this often provides for many students opposed to just being taught the procedures (Reys et al., ch. 12.1). It will be further looked at the important factors to remember when developing a solid conceptual understanding and connection to multiplicative thinking, fractions and decimals.
A Year in the Life of an Elementary School: One School's Experiences in Meeting New Mathematics Standards
Mathematics, like every creation of man, have evolved without really knowing how far you can get with them: the scope of the computer, physics, chemistry, algebra, all are evidence of this. Every aspect of our culture is based in some way or another in Mathematics: language, music, dance, art, sculpture, architecture, biology, daily life. All these areas of measurements and calculations are accurate. Even in nature, everything follows a precise pattern and a precise order: a flower, a shell, a butterfly, day and night, the seasons. All this makes mathematics essential for human life and they can not be limited only to a matter within the school curriculum; here lies the importance of teaching math in a pleasure, enjoyable and understandable way. Mathematics is an aid to the development of the child and should be seen as an aid to life and not as an obstacle in their lifes.
The lack of adopted curriculum also means that most, if not all, teachers are supplementing both materials and instructional routines. These students need to pass the state-mandated Smarter Balanced Assessment (SBA) which requires completion of a problem-solving performance task. Students need to know which operation(s) to use (addition, subtraction, multiplication, and/or division) and how to apply them appropriately. This problem has
Current nationwide examination outcomes offer continuing paperwork of the should enhance the concentrate on enhancing student accomplishment in mathematics. The National Evaluation of Educational Development (NAEP) just recently launched the 2005 mathematics ratings which mirrored student accomplishment in the locations of dimension, geometry, information analysis, likelihood and algebra. Country wide, just 30 % of 8th graders were considered competent. Although mirroring a boost from previous evaluations, just 69 % of the 8th graders country wide showed a standard abilities level on the NAEP evaluation (Olson, 2005).
