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…

Discusses a meaningful experience, conceptually, of multiplication of fractions. (Author/YDS)

Describes a framework to help teachers decide when to use calculators with their students. (YDS)

Discusses a content-integration program in which Spanish is introduced while mathematics and other subjects are reinforced, creating a winning combination for students, teachers, and preservice teachers alike. (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)

Focuses on children making sense of multiplication. In an activity called "Silent Multiplication," students use what they know about easier multiplication problems to solve increasingly difficult, related problems mentally. (Author/NB)

Develops computational fluency using a game format. Activities involve a standard deck of playing cards. (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 number of transcript examples of correct and incorrect transferences by children. Considers the objects of transference including spoken words, written symbols, models and diagrams, arithmetic procedures, and structures. Discusses the use of transference in arithmetic education. (YP)

An Angoff method and a frequency estimation equipercentile equating method were compared, using data from three forms of a 200-item multiple-choice certification test. Data requirements are fewer and computational requirements less burdensome for the former than for the latter method. However, results of the two methods are not interchangeable.…

Examined Piaget's claim that young children have difficulties constructing common multiples because of an inability to abstract the number of actions performed to obtain a number of objects. Subjects were two groups of preschool children in sharing tasks. Results showed improvement in performance based on certain conditions, but the significance…

Describes activities that will help students calculate the volume of water carried by a river or stream and how to measure the amount of water wasted by leaky faucets. (MDM)

Provides measurement, estimation, and data analysis activities for grades three to four and five to six using boxes of cereal and containers of frozen yogurt. (MKR)

This study of 15 pupils (ages 7-10) with severe learning difficulties found that mental age (as measured by the British Picture Vocabulary Scale--a measure of receptive language ability) was correlated with counting performance. The study also found that being able to count accurately did not automatically lead to understanding the principles of…
