The data presented here belongs to a teaching experiment in which the use of relational thinking when solving number sentences was explicitly promoted. Carpenter, T.

Thinking Mathematically : Integrating Arithmetic & Algebra in Elementary School
Sitting in Mrs. Peavey's Algebra I class, I experienced algebra much like millions of other Americans—as an intensive study of the last three letters of the alphabet. I failed to grasp the importance of algebra—how it provides support for almost all of mathematics or to understand its power as a tool for analytical thinking. It was a course I endured to get into college. Thirty years later, algebra is not just for those who plan to attend college, but for everyone. Robert Moses, founder of the Algebra Project, says that in today's technological society, algebra has become a gatekeeper for citizenship and economic access. As the world has become more technological, the reasoning and problem solving that algebra demands are required in a variety of workplace settings.
In Stock. In Children's Mathematics: Cognitively Guided Instruction , Thomas Carpenter, Megan Franke, and Linda Levi helped hundreds of thousands of teachers understand children's intuitive problem-solving and computational processes and how to use that knowledge to enhance students' understanding of arithmetic. In Thinking Mathematically , the same author team shows how Operations and Algebraic Thinking can be viewed as a unified field by understanding how children's intuitive strategies naturally draw upon the properties of operations and other algebraic concepts. This book also shows how teachers can increase their own knowledge of mathematics in the process of interacting with their children and reflecting about their practice. Thinking Mathematically provides numerous examples of classroom dialogues that indicate how properties of operations and other algebraic ideas emerge in children's thinking and what problems and questions help to elicit them. Special features of the book help teachers develop their own understanding of mathematics along with their students':.
Algebraic reasoning is an essential habit of mind for building conceptual knowledge in K mathematics, yet little is known about how middle school mathematics teachers think about algebraic reasoning. In this article we describe a research project examining how algebraic reasoning was considered by grades 6, 7, or 8 mathematics teachers in a two-week professional development and over the following two months. We found these 21 teachers initially described algebraic reasoning in a way requiring only procedural knowledge to solve problems with a single solution, solution strategy, or representation. Teachers reported three activities influenced a shift in their thinking about algebraic reasoning, specifically by requiring conceptual knowledge to solve problems using multiple solutions, solution strategies, or representations. While some teachers also associated aspects of generalization and functional thinking as part of algebraic reasoning, two months after the professional development no teachers continued to associate these aspects as part of algebraic reasoning.

This paper aims to optimize Sundanese ethnomathematics learning by improving the creative thinking ability of mathematics, geometry thinking, and algebra of primary school students. Teaching materials prepared by qualitative research, the didactical design research method. The research subject which used in the learning obstacle test is the fifth-grade primary school students with a total of 71 students.
It's Elementary: Introducing Algebraic Thinking Before High School
We have characterized what we call relational thinking to include looking at expressions and equations in their entirety rather than as procedures to be carried out step by step. For the last 8 years, we have been studying how to provide opportunities for students to engage in relational thinking in elementary classrooms and how to use relational thinking to learn arithmetic. In this article, we present interviews with two third-grade students from classrooms that foster the use of relational thinking.
In this paper, we provide evidence of the impact of early algebra EA over time. We document this impact in the following ways: a by showing the performance over time of an experimental group of 15 children on an algebra assessment, from 3 rd to 5 th grade; and b by showing how the performance on an algebra assessment of children from an experimental group differs from the performance of a group of comparison students from their same elementary school who did not receive EA instruction from 3 rd to 5 th grade. Our results highlight the positive impact of an early access to algebra, indicating that this early access is associated, when we compare 3 rd graders to 5 th graders, with increased scores on items that involve inequalities and graphs. When comparing experimental to comparison-group students we find increased scores on items that involve variables, functional relations, intra-mathematical contexts, tables, and algebraic expressions. The study adds to a body of literature that has been arguing for EA as well as a need to thread algebra throughout the mathematics curriculum, starting in the earliest grades. Bednarz, N.
This study mainly focused on the relationship between number sense and algebraic thinking. Previous studies have provided evidence that number sense plays an important role in developing algebraic thinking. The role of symbol and pattern sense are yet to discover in relation to number sense and algebraic thinking. To do so, two mathematics tests were carried out among year five pupils in the district of Malacca, Malaysia. The collected data were analysed using a partial least squares-structural equation modeling approach. The data collected were analysed using SPSS
