Experiments are described in which students listened to messages describing the placements of numbers in imaginable matrices. Recall was tested by having students write in the correct cells of a blank matrix. Results appear consistent with a modified level of processing approach. (Author/RM)

An imaginary journey to Planet Seven is used to introduce the concept of number systems not based on ten. Activities include making a base 7 chart, performing base 7 addition and subtraction, designing Planet Seven currency, and developing other base systems for other planets. (MT)

This paper documents a study concerned with examining the affective response to mathematics among 45 primary school students. The study sought to examine how the children's emerging beliefs, attitudes and feelings about mathematics impacted on their learning of the subject. A particular finding was that these beliefs, attitudes and feelings were…

This textbook is an introductory mathematics course. It is a treatise of arithmetic, containing all the practical parts thereof; both in whole numbers, vulgar fractions, and decimals; likewise the theory of numbers, and their principal properties, demonstrated in a plain and easy manner.

This arithmetic textbook uses small concrete numbers to lead pupils to understanding numbers' properties and relations. This work is intended as a connecting link between the Primary and Written Arithmetics of the Author. It presents a mental analysis of Arithmetic adapted to the younger pupils by its easy gradations, and to advanced pupils by its…

Research investigating the performance of students in grades 4 through 7 on varying items involving the distributive property is reported; results, showing low performance levels, are analyzed. (DT)
