Documents the experiences of two teachers and their kindergarten and first-grade students in working with calculators as an ongoing and integral component of their mathematical programs. Focuses on ways that the children and teachers use the calculator to develop ideas of number through explorations of numerals, counting, number magnitude, and…

Explores ways to help children make connections between whole-number multiplication and their notion of a fraction. Illustrates an approach to constructing fraction concepts that builds on children's whole-number knowledge using specially designed computer tools. (KHR)

Describes the Calculator-Aware Number (CAN) curriculum developed by the Primary Initiatives in Mathematics Education (PrIME) project. Summarizes the CAN curriculum as it relates to learning by children and use by teachers. (YP)

It is argued that number sense develops through meaningful, purposeful activities involving calculating, measuring, and estimating. Understandings that must be developed with each are discussed. More emphasis needs to be placed on thinking about the various procedures that can be used to solve problems and on interpreting the answers. (MNS)

Suggestions for incorporating number sense into lesson warm-ups, lesson development, and practice exercises are provided. Ideas for developing a positive climate for thinking numerically are given. Then when, where, and how to develop number sense are discussed. (MNS)

Simple experiences with probability can extend third graders' understanding of the need for fractions. Three activities are given which build on language-arts experiences and incorporate concepts in multiplication, graphs, and fractions. (MNS)

Several problem-solving activities involving only 0-9 to be used with sets of ceramic tiles are presented. Finding specified sums, differences, or products is the object of most of the problems. (MNS)

The article relates the British PrIME (Primary Initiatives in Mathematical Education) Project to children with special educational needs doing mathematics. The project's main aim is to improve the mathematical understanding and teaching skills of primary teachers. Activities using calculators are described. (DB)

Presents a covariation approach to learning exponential and logarithmic functions based on a primitive multiplicative operation labeled splitting that is not repeated addition. Suggests that students need the opportunity to build a number system from splitting structures and their geometric forms. (30 references) (MKR)

Discusses explorations that students can engage in using the interstate highway system. (MKR)

The objective of this activity is to help beginning students learn numbers and practice vocabulary and verbs in an interesting and meaningful way. In addition, the game is used to improve their listening comprehension and speaking ability. (Author/CK)

Presents an activity using base-10 blocks and the TI Explorer calculator to help fifth and sixth graders represent their ages in different numerical bases to appear older or younger than their real age. (MKR)

An algebra test administered to (n=18) first-year college students found a disregard for negative numbers, ineffective use of counterexamples, misapplication of rules, and a lack of a good grasp of relevant mathematical terminology. (12 references) (MKR)

Many students can calculate the arithmetic mean but do not understand the concept. The article presents four activities designed to help elementary and middle school students develop this concept. The activities presented assume previous exposure to the computational algorithm for the arithmetic mean. (Author/EK)

Describes a school-wide project using popcorn to gain number sense by learning more about a million. Used the books "How Much Is a Million?" and "If You Made a Million" to introduce the project. (MKR)
