ab: Publisher’s description: Why do some equations have one solution, other
two or even more solutions, and some no solutions? Why do we sometimes
need to “switch” the direction of an inequality symbol in solving
an inequality? What could you say if a student described a function as
an equation? How much do you know\dots and how much do you need to
know? Helping your students develop a robust understanding of
expressions, equations, and functions requires that you understand this
mathematics deeply. But what does that mean? This book focuses on
essential knowledge for teachers about expressions, equations, and
functions. It is organized around five big ideas, supported by multiple
smaller, interconnected ideas ‒ essential understandings.Taking you
beyond a simple introduction to expressions, equations, and functions,
the book will broaden and deepen your mathematical understanding of one
of the most challenging topics for students ‒ and teachers. It will
help you engage your students, anticipate their perplexities, avoid
pitfalls, and dispel misconceptions. You will also learn to develop
appropriate tasks, techniques, and tools for assessing students’
understanding of the topic. Focus on the ideas that you need to
understand thoroughly to teach confidently.
