Two games and one activity designed to be used with a hand-held calculator are presented. (MK)

An algorithm for multiplying natural numbers is described. The algorithm provides a chance for some unusual drill and might serve as an enrichment topic. (MK)

Ways to use popsicle sticks as concrete models of multiplication and division of fractions are given. (MK)

The multiplication and division algorithms that are taught in German schools are presented. It is suggested that these algorithms may be better than standard algorithms in terms of development of useful concepts and processes. (MK)

Some techniques for developing the ability to multiply and divide by powers of ten with ease and understanding are presented. (Author/MK)

A method of teaching multiplication facts to remedial students using fingers and an alternate geometric proof developed by students are suggested. (MK)

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

Drill activities for addition, subtraction, multiplication, and division that are derived from the history of mathematics are suggested. (MK)

A new approach to teaching the division of common fractions is described. The approach is related to the multiplication operation and involves children working with concrete materials. (MK)

Directions for making a device that parents can use to help children practice basic skills are given. (MK)

Two posters that can be used to provide experience in recognizing patterns in sequences of numbers are provided. Suggested number sequences for different grade levels are given. (MK)
