Understanding Number Concepts Book Set

Understanding Numbers
3 Part Station Series
by Kathy Richardson

Grades: 3-5
Price: $36.00 Each

The Understanding Numbers series of stations are sets of 8 tasks that provide students with the meaningful practice necessary for developing an understanding of the underlying structure of numbers, number relationships and operations. The mathematics presented in the stations is foundational and crucial for developing computational fluency. These foundational concepts also provide the basis for students' understanding of the mathematics they will encounter in the future. Titles include either Place Value, Addition & Subtraction, or Decimals.

Each set of stations presents a variety of activities focused on one major concept. The tasks are designed to meet a range of needs allowing all students to work at their own level. These stations should be experienced over and over again until students have developed proficiency with the tasks. Most students will benefit from working with the appropriate set of stations for several weeks.

Each station book comes bundled with Station Cards and Task Cards — printed on colored card stock, suitable for repeated classroom use.

Posing Open-Ended Questions
in the Primary Math Classroom Book Posing Open-Ended Questions
in the Primary Math Classroom
by Christina Myren

Grades: K-2
Price: $21.95

Bring the Common Core Practice Standards to life in your classroom!

Posing Open Ended Questions in the Primary Math Classroom is an outstanding resource for teachers as they work toward making mathematics meaningful and relevant to children. This book is a collection of 15 open-ended mathematics questions for kindergarten, first, and second-grade children. It is a wonderful addition to any math curriculum because it raises the standards of K-2 mathematics and exemplifies the depth of mathematical thinking that young students are truly capable of doing. Christina Myren has provided many examples of student work that show a wide range of responses and growth over time.

The problems are open ended because they have multiple solutions and/or multiple approaches to reach one solution. Children's literature serves as a springboard for many of the lessons. Each lesson contains an overview, materials list, description, student responses and assessment discussion, and references.
