A graphing activity which allows students to work independently of the teacher and the textbook is described. The activity involves providing data in order to develop the skills necessary for interpreting the collected information. (JT)

Specific suggestions for teaching young children (ages 5-7) mathematical principles are offered, covering such concepts as addition, subtraction, multiplication, division, arithmetical laws, and utilizing a story to teach various mathematical concepts and skills. (DB)

Activities that are helpful for teachers and pupils alike in getting the feel for how big a million really is are suggested. (DT)

Plastic Easter eggs are useful devices for teaching basic mathematics skills, from counting activities to graphing. Eggs are used to reinforce addition, subtraction, and multiplication skills; column addition, estimation, statistics, and other topics are introduced. Sample activities are described. (JL)

A general method and a variant for divisibility are presented, with specific examples. (MNS)

An ant city is used as the basis for counting and other numerical activities. (DT)

An investigation of these numbers is shown to give students an opportunity to make use of such mathematical skills as algebraic substitution, modular arithmetic, counting arguments, and mathematical induction. (MP)

Two algorithms are developed for finding the square roots of numbers. One is based on the rule that x square is the sum of the first x odd numbers; the other is algebraic. (MP)

A number of activities are suggested that provide motivation and increases the confidence of students involved in practicing numerical skills. (MP)

A method of multiplying using fingers is described and an explanation given. The method is then generalized to other number bases. (MP)

Presents a project in which one science class, curious about large numbers, created one million marks on paper. Discusses other concrete representations of one million and other large numbers. (MKR)

Describes public key cryptography, also known as RSA, which is a system using two keys, one used to put a message into cipher and another used to decipher the message. Presents examples using small prime numbers. (MKR)

A classroom activity in which numbers are assigned to words on the basis of geometric configuration of the letters is described. (SD)

Three topics related to teaching mathematics are discussed: a problem with the order of operations, teaching fractions, and an application of the distributive property. (MP)
