The assumption that subjects compare symbolic stimulus magnitudes with respect to a reference point was examined. Results indicate that subjects can strategically vary the process for comparing stimuli to a reference point and can perform various types of analog arithmetic using the linear number scale or a nonlinear scale of subjective digit…

Instructional sequences are presented for teaching two-digit multiplication and division with one- and two-digit divisors using a base-oriented approach. (MN)

Investigated with three Down's Syndrome girls (aged 6-7 years) was the hypothesis that a videotape recording of a child correctly identifying numbers would serve to increase her number competency. (JYC)

Relationships between elementary analytic geometry and several types of number sequences are discussed. (JT)

Four games that provide practice with fractions are described. The games involve naming fractional parts, identifying equivalent fractions, adding fractions, and multiplying fractions. (JT)

Suggestions and examples are given for changing the passive bulletin board into an activity-oriented bulletin board which aids in teaching mathematics. (JT)

Methods that have been used with a high degree of success in correcting errors in subtraction are discussed. (JT)

Four games that reinforce the concepts of place value and ordering numbers are described. (JT)

An approach is illustrated that introduces selected models of addition and subtraction to students who have previously learned a model for either operation. (JT)

A game for two teams employs dice, meter sticks, and Cuisenaire rods. The game gives practice in number facts, regrouping, and use of rods; it can also serve as an introduction to the metric system. (SD)

Games which use dominoes, dice, and playing cards to promote computational skill are described. (SD)

The informal arithmetic inventory, an informal diagnostic technique for use with elementary age students, indicates a child's specific weaknesses in arithmetic, such as inadequate concept development, poor computational skills, or inability to apply skills in a practical problem solving situation. (SBH)

Described is a multiplication unit for intermediate aged emotionally disturbed boys which used citizen band radio terms and a drawing of a road to record individual progress. (CL)

Reports on a study to determine the development of children's understanding of seven properties of the arithmetic mean and to assess the effects of material used in the testing and the medium of presentation. Some differences were found in children's reasoning. No significant differences were found for materials or medium of presentation. (PK)

An elementary school mathematics program can be structured to allow students to practice computational skills and also become familiar with concepts that need to be mastered in algebra. The activities described begin with students' life experiences, continue through concrete and pictorial experiences, and conclude with abstract activities and…
