The study compared two methods of teaching an initial place value skill: a concrete, semiconcrete, abstract teaching sequence and an abstract-only presentation. Learning-disabled elementary and middle school students (N=24) using the concrete to abstract teaching sequence performed significantly better on three posttests than students taught the…

Two experiments involving a total of 40 three and 39 four year olds were undertaken to determine subjects' ability to sort and compare numbers according to magnitude. Results indicate that readiness skills for early childhood mathematics education should include development of appropriate concepts of number magnitude. (TJH)

Investigates the relationship between the home experiences of six children aged five years and their level of numerical understanding. High scorers were characterized by exposure to a wide range of number experiences, a strong family orientation towards numeracy, and the opportunity to observe their mothers using numbers to solve everyday…

Elementary and middle school education majors in Australia (n=326) and the United States (n=378) were asked to arrange a list of decimals in order from smallest to largest. Only about half of these preservice teachers in each country were able to complete the task correctly. (MKR)

Presents five teaching ideas which incorporate ideas related to baseball. Includes student worksheets. (MKR)

Eight students with Down's syndrome, aged 11 through 13, were taught to add by counting-on in a 5-day teaching program. Teaching included instruction in component skills and use of precision teaching techniques. All students continued to use the technique six months later and generalized the technique to other materials. (Author/DB)

Preschoolers' performance on two tasks demonstrated that, given a perceptually available set of dolls, they were able to use number words to determine the quantity of a hidden or nonexistent set of items that was in a known ratio to the available set. (MM)
