The Whole Truth About Whole Numbers is an introduction to the field of Number Theory for students in non-math and non-science majors who have studied at least two years of high school algebra. Rather than giving brief introductions to a wide variety of topics, this book provides an in-depth introduction to the field of Number Theory. The topics covered are many of those included in an introductory Number Theory course for mathematics majors, but the presentation is carefully tailored to meet the needs of elementary education, liberal arts, and other non-mathematical majors. The text covers logic and proofs, as well as major concepts in Number Theory, and contains an abundance of worked examples and exercises to both clearly illustrate concepts and evaluate the students’ mastery of the material.
"How do you see India? Fuelled by a surge of migration to cities, the country's growth appears to be defined by urbanisation and by its growing, prosperous middle class. It is also defined by progressive and liberal young Indians, who vote beyond the constraints of identity, and paradoxically, by an unchecked population explosion and rising crimes against women. Is it, though? In 2020, the annual population growth was down to under 1 per cent. Only thirty-one of hundred Indians live in a city today and just 5 per cent live outside the city of their birth. As recently as 2016, only 4 per cent of young, married respondents in a survey said their spouse belonged to a different caste group. Over 45 per cent of voters said in a pre-2014 election survey that it was important to them that a candidate of their own caste wins elections in their constituency. A large share of reported sexual assaults across India are actually consensual relationships criminalised by parents. And staggeringly, spending more than Rs 8,500 a month puts you in the top 5 per cent of urban India. Data-journalism pioneer Rukmini S. draws on nearly two decades of on-ground reporting experience to piece together a picture that looks nothing like the one you might expect. There is a mountain of data available on India, but it remains opaque, hard to access and harder yet to read, and it does not inform public conversation. Rukmini marshals this information - some of it never before reported - alongside probing interviews with experts and ordinary citizens, to see what the numbers can tell us about India. As she interrogates how data works, and how the push and pull of social and political forces affect it, she creates a blueprint to understand the changes of the last few years and the ones to come - a toolkit for India."-- dust jacket.

This twenty-third ICMI Study addresses for the first time mathematics teaching and learning in the primary school (and pre-school) setting, while also taking international perspectives, socio-cultural diversity and institutional constraints into account. One of the main challenges of designing the first ICMI primary school study of this kind is the complex nature of mathematics at the early level. Accordingly, a focus area that is central to the discussion was chosen, together with a number of related questions. The broad area of Whole Number Arithmetic (WNA), including operations and relations and arithmetic word problems, forms the core content of all primary mathematics curricula. The study of this core content area is often regarded as foundational for later mathematics learning. However, the principles and main goals of instruction on the foundational concepts and skills in WNA are far from universally agreed upon, and practice varies substantially from country to country. As such, this study presents a meta-level analysis and synthesis of what is currently known about WNA, providing a useful base from which to gauge gaps and shortcomings, as well as an opportunity to learn from the practices of different countries and contexts.

Prealgebra 2e is designed to meet scope and sequence requirements for a one-semester prealgebra course. The text introduces the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics. Students who are taking basic mathematics and prealgebra classes in college present a unique set of challenges. Many students in these classes have been unsuccessful in their prior math classes. They may think they know some math, but their core knowledge is full of holes. Furthermore, these students need to learn much more than the course content. They need to learn study skills, time management, and how to deal with math anxiety. Some students lack basic reading and arithmetic skills. The organization of Prealgebra makes it easy to adapt the book to suit a variety of course syllabi.
Through error analysis and targeted instruction, you can uncover students' misconceptions in addition, subtraction, multiplication, and division and help students understand and correct their own mistakes!
Does your classroom run the way you want? Most people enter the teaching profession wanting to make a difference in young people's lives. However, more and more teachers feel lost, frustrated, and overwhelmed with everything they're required to do. It's hard to be successful without a clear plan on getting control of your classroom, empowering your students, and making the learning experience more enjoyable for you and your students. These 18 chapters are crucial for any educator who wants to take their teaching to the next level. Teacher, Principal, Director, Dean, and YouTube/TikTok teacher, Tyler Tarver knows that education is more than just standing in front of students lecturing them on a specific topic - it's a culture of learning that educators foster to train the next generation. If you are attempting to be the best educator you can in the environment you're in, you need ideas and encouragement from someone who's been exactly where you are. Even if you had the time, money, and support we know teachers deserve, we know that applying any knowledge always has a greater impact when you're able to give personal and practical application to the ideas you know matter. Besides sitting through 60+ hours a year of professional development, there is another way to incrementally improve your teaching week after week. Spoiler Alert: It can also be fun. Tyler Tarver learned how to create the culture he wanted in his classroom. He was able to pass this on to any educator who wanted to get excited about teaching and have a deeper impact on their students. He wrote The Baller Teacher Playbook to teach others what it takes to expand your teaching and create a community of happy and engaged learners. These short, weekly chapters and accompanying resources will add enormous value to your classroom and the school you work for.

Because fluency practice is not a worksheet. Fluency in mathematics is more than basic facts or using algorithms. It is not about recall or speed. Real fluency is about choosing strategies that are efficient, flexible, lead to accurate solutions, and are appropriate for the given situation. Developing fluency is a matter of equity and access for all learners. The landmark book Figuring Out Fluency in Mathematics Teaching and Learning offered educators the inspiration to develop a deeper understanding of procedural fluency. It explained the seven Significant Strategies for fluency and offered a plethora of pragmatic tools for shifting classrooms toward a greater fluency approach. However, in order to become truly adept with these strategies, children must first have certain underlying foundational concepts and skills in place. Figuring Out Fluency-Ten Underlying Foundations for Reasoning Strategies with Whole Numbers explores the ideas that are essential to reasoning: Number Relationships; Subitizing and Decomposing; Distance to 10, 100, and 1,000; Counting and Skip-Counting; Properties of Addition and Its Inverse Relationship with Subtraction; Properties of Multiplication and Its Inverse Relationship with Division; Multiplying by 10s and 100s; Multiples and Factors; Doubling and Halving; and Computational Estimation. With this book, elementary teachers can Help children develop these foundational understandings, critical to reasoning and number sense. Leverage over 100 classroom-ready routines, centers, and games to develop these concepts both in first instruction, practice, and intervention. Download all of the needed support tools, game boards, and other resources from the companion website for immediate implementation Develop each and every students’ knowledge and power to become skilled and confident mathematical thinkers and doers.
This book offers a theory for the analysis of how children learn and are taught about whole numbers. Two meanings of numbers are distinguished – the analytical meaning, defined by the number system, and the representational meaning, identified by the use of numbers as conventional signs that stand for quantities. This framework makes it possible to compare different approaches to making numbers meaningful in the classroom and contrast the outcomes of these diverse aspects of teaching. The book identifies themes and trends in empirical research on the teaching and learning of whole numbers since the launch of the major journals in mathematics education research in the 1970s. It documents a shift in focus in the teaching of arithmetic from research about teaching written algorithms to teaching arithmetic in ways that result in flexible approaches to calculation. The analysis of studies on quantitative reasoning reveals classifications of problem types that are related to different cognitive demands and rates of success in both additive and multiplicative reasoning. Three different approaches to quantitative reasoning education illustrate current thinking on teaching problem solving: teaching reasoning before arithmetic, schema-based instruction, and the use of pre-designed diagrams. The book also includes a summary of contemporary approaches to the description of the knowledge of numbers and arithmetic that teachers need to be effective teachers of these aspects of mathematics in primary school. The concluding section includes a brief summary of the major themes addressed and the challenges for the future. The new theoretical framework presented offers researchers in mathematics education novel insights into the differences between empirical studies in this domain. At the same time the description of the two meanings of numbers helps teachers distinguish between the different aims of teaching about numbers supported by diverse methods used in primary school. The framework is a valuable tool for comparing the different methods and identifying the various assumptions about teaching and learning.
