In this qualitative study of students? methods of calculating Subtractions, I have used interviews, Subtraction exercises and analysis of teaching material. The purpose of my study was to explore which methods students in grade three uses when calculating Subtractions. I also wanted to highlight which strategies the students use and their comprehension of the concept of Subtraction. In the study, I also highlight the different pedagogical ideas on which the teaching material is based on and the students? choice of methods.  The study shows that the students choose to use the methods?deduct? and ?kind of number? independently.

 Title:              Not just words, classroom communication about Subtraction in year 2Language:      Swedish with summary in English.Keywords:     Communication, mathematics, Subtraction, teaching The purpose of this study is to analyze the mathematical communication in a classroom during a lesson in the field Subtraction, and to find out how students describe their perception of mathematics that is communicated in the classroom.The study consists of the observations through the videotaping of two lessons in primary school grades 2 and student and teacher interviews related to these lecture occasions.Research indicates that Swedish pupils' mathematical skill continuously deteriorates in a national and international perspective, and that student experiences of mathematics in general are negative. The literature emphasizes the importance of communicating mathematics in various forms to deepen and develop understanding of concepts and mathematical operations. Communication must be generated between teachers and students but also between student and student to have a beneficial impact for the student.Our result demonstrate the different types of communication in the classroom but that communication does not always have a clear mathematical content in spite of teachers' mathematical intentions with teaching. The result also indicates that the mathematical communication that takes place, in essence, is a one-way communication where the teacher has a great opportunity to speak. The teachers perceived as oblivious to their own ways of communicating, but stressed in the interviews with an understanding of the importance of communication learning.

Syftet med denna studie var att undersöka elevers användning av lösningsstrategier i subtraktion samt lärares och läromedlens framställning av dessa, för att kunna komma fram till hur en framgångsrik undervisning i subtraktion, med fokus på lösningsstrategier, kan se ut. Undersökningen genomfördes i tre klasser i åk 3. Metoder i studien var elevenkät, intervju med lärare och läromedelsgranskning. Data bearbetades med hjälp av en egenkonstruerad begreppsmodell utifrån olika lösningsstrategier. Resultatet visar på en större variation av lösningsstrategier i undervisningen än i elevernas uträkningar.

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.

The word mathematics is often associated to addition, Subtraction, division or multiplication. This is not the kind of mathematics that belongs to pre-school. In my essay I have chosen to write about how mathematics is used in pre-school. In the literature it is written that the best way of becoming familiar with mathematics, is to integrate it in the every day life but that there are educators that use traditional mathematics education in pre-school. The questions I would like to answer are:1.

Abstract The purpose of this degree project is to examine what impact working with physical objects has on children?s learning process concerning addition. We want to explore what addition strategies can be exercised using the game ?Twice as much?. We have observed children in school year 1.

The information technique is developing at a fast pace and almost all new technique is being welcomed with opened arms. The newest on the market is the tablet device, it´s a device used for surfing the web, sending email, watching movies and playing games. It is now also being used in some schools for educational purposes. My research goal has been to find out how the teachers feel about using the tablet device for educational purposes. I have conducted interviews to find the answers to my questions.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

Our work is based on a mathematics test which the students accomplished, interviews with student and teachers who are working on this program and the current literatures. The purposes of this work are to search the importance and the effect of the languages understanding in students learning of mathematic in the Individual high school curriculum. In total, sex students and three teachers took part in our study. Tow of the students is mother tongue language student and the remains are second language student. Our study should answer tow important questions:? Do the student in the Individual high school curriculum have the fundamental knowledge in mathematic?? How does the understanding of Swedish language effect in the understanding of the mathematic problems and in the students results in mathematic test?In order to answer those questions, the students have to complete a mathematic test that consists of four parts.
