Activities are presented that focus on attributes of numbers. The activities highlight such attributes as more than, equal to, greater than, less than, LCM, prime and factor. The activities provide practice in motivational game-oriented situations. (RH)

The authors suggest how the patterns in the digits in the multiplication tables may be exploited in the classroom. (MM)

A rationale is given for the Russian-peasant algorithm for multiplication indicating why it works as well as how it works. (DT)

The Russian-peasant algorithm for multiplication is described and then extended to developing an algorithm for renaming base ten numbers in other number bases. (DT)

Six activities useful in developing the idea of prime factorization are described. Some of these activities are best done with a calculator. (MK)

Patterns and relationships found in the multiplication table of the numbers zero through nine are discussed as a means to helping students understand certain concepts. (MP)

Activities are described which make use of rectangular arrays as a means of illustrating multiplication facts and the distributive property. (DT)

Shortcuts for multiplying by eleven are presented and explained. (DT)

Four worksheets showing how number patterns may be used to give extra practice and insight into the decimal numeration system and the basic properties of arithmetic. (MM)
