Using Cuisenaire Rods, metric measurement, and mapping, students worked collaboratively to calculate, keep records, build, and problem solve with use of decimal fractions as a key element.

"Classroom number talks," five- to fifteen-minute conversations around purposefully crafted computation problems, are a productive tool that can be incorporated into classroom instruction to combine the essential processes and habits of mind of doing math. During number talks, students are asked to communicate their thinking when presenting and…

This article describes one teacher's journey to improve her teaching of mathematics by conducting classroom-based inquiry to meet the specific mathematical needs in her second grade classroom. Her process to develop and improve computational fluency through research-based methods is detailed. (Contains 9 figures.)

Presents a series of reflections in which a second-grade teacher recognizes the value of encouraging children to develop various computational processes as well as a range of different solution approaches. Uses the context of mentally calculating costs of menu items. (MKR)

Discusses the relationship between computational fluency and number sense in early childhood mathematical development. (Author/NB)

Suggests that algorithms, both traditional and student-invented, are proper objects of study not only as tools for computation, but also for understanding the nature of the operations of arithmetic. (Author/NB)

Describes the work that students and teachers do to develop computational fluency for subtraction. Examines the orchestration of whole-class discourse and presents a collection of common strategies. (Author/NB)

Suggests ways to increase students' computational fluency using concrete materials, engaging tasks, and reflection time to increase number automaticity, flexibility in thinking about numbers, and use of efficient problem-solving strategies to find sums and differences. (Author/NB)

Discusses classroom practices that promote the understanding of number concepts in the primary grades. (Author/NB)

Explores young children's intuitive strategies for partitioning sets of objects. (Author/NB)

Discusses how teachers can help English-language learners develop computational fluency. (Author/NB)

Discusses the positive results of incorporating two essential elements of learning--language patterns and visualization--found in Japanese classrooms into a first grade classroom in Minnesota. (Contains 12 references.) (Author/YDS)

Presents a problem involving fractions for discussing and sharing of student responses to the problem at a later date. (KHR)

Examines the philosophy behind the issue of computational fluency in "Principles and Standards." (Author)

Describes a multicultural enrichment project for 4th graders that highlights number systems and computation algorithms of various cultures. Discusses student responses and reactions. (KHR)
