Difficulties encountered by a dyscalculia child are discussed and remedial activities suggested. Disturbances discussed are verbal, visual-spatial, reading and writing numbers, operations, understanding concepts, and place value. (MP)

Two inquiry-oriented lessons that involve students in numerous computations, but are also enjoyable mathematics activities, are described. Drill activities are camouflaged by the challenge of a game. (MP)

A series of lessons concerning money and place value is described and instructional techniques are analyzed. (DT)

Ways in which elementary children can learn the concept of "zero" are described. (DT)

Sidelights and extensions of factorability are presented. (DT)

Describes how one kindergarten classroom made pictographs and paper graphs of the students' acting preferences for a production of "The Wizard of Oz." Focuses on how the activity led to varied mathematics and literacy connections. Identifies implications from the Oz experience, including relating graphs to classroom contexts, using…

Enumeration and numerical reasoning levels of 19 children with specific language impairment (SLI) were compared to children matched for age and children matched for grammatical ability (GM). Children with SLI performed better than the GM group on reproduction of sets, numerosity of sets, an addition/subtraction condition, and transformation…

Interrelationships between problem solving and number sense are discussed. Suggestions are given on helping children to search for a solution process and to reject unreasonable answers. The teacher's role in developing number-sense skills with problem-solving tasks is also discussed. (MNS)

Questions students raise about the meaning of zero to the zero power present an opportunity for mathematics teachers to involve students in active participation in exploring mathematical relationships. Calculators are the needed tool to make this exploration accessible to students. How they can be used is described. (MNS)

Presents lessons and reproducible student worksheets for grades three to four and grades five to six to investigate large numbers and comprehend their magnitude. (MKR)

Presents reasons for, and examples of, addressing environmental issues in secondary mathematics classrooms. (Author/MKR)

Examines ways to integrate a discussion of lotteries into a lesson on combinatorics and probability to enhance the teaching and learning of number sense. (Author/MKR)

Presents a summary report of a discussion subgroup of the Algebra Working Group at the Seventh International Conference on Mathematics Education held in Quebec City, Canada in August 1992. Argues that pre-algebra should be viewed as a continuation of arithmetic that asks different questions about numbers. (12 references) (Author/MKR)

Discusses some of the history of casting out nines and the controversy surrounding its use as a method of checking. (17 references) (MKR)

Mildly retarded preadolescents received equality-rule training, or instruction in which identical or different numbers were applied to identical or different quantities. In tasks of conservation of number, length, weight, and volume, these preadolescents scored higher than did preadolescents who received other types of training. (BC)
