A modified method of regrouping the minuend for subtraction is described. This more flexible method decreases the number of steps in the subtraction process and in checking the regrouping. (SD)

The mathematics associated with division is discussed, working from a theorem for the real division algorithm. Real-world, geometric, and algebraic approaches are discussed, as are related topics. (MNS)

Two difficulties that students have in computing with fractions are idenfitied. Then a procedure is described, stressing the identity element, that resolves these difficulties and increases students' understanding and retention. (MNS)

How the strategy of uninterrupted sustained silent reading, can be adapted as uninterrupted sustained arithmetic for use in mathematics classes and clinics is discussed. Several activities are described and illustrated. (MNS)

The focus is on the problem-solving strategy "write an equation." Other topics to develop problem-solving skills are included. (MNS)

Solving a problem using the work-backward strategy is discussed, with tips on other facets of problem solving. (MNS)

Reported are the findings of a study of over seven hundred fourth-, sixth-, and eighth-grade pupils' ability to understand division involving zero. Implications for the classroom are discussed, including suggested teaching strategies. (JP)

A concrete approach to subtraction problems with minuends to 19 is presented. (MP)

The use of the hundred chart is discussed as an effective means of teaching the concepts of least common multiple and greatest common factor. (MP)

A series of carefully planned activities is described for introducing first-grade students to place value with two-digit numerals. (JT)

Use of an ancient method of mental calculation with aliquot parts is illustrated. Other tips for helping children reason are also included. (MNS)

Suggestions are provided on diskette care, software worth seeing, teaching that computers can't do everything, and a debugging activity. (MNS)

Describes a strategy in which mathematics is taught using a tournament format. Planning for a tournament, tournament rules, and procedures (with sample problems) are included. (JN)

Ways in which newspapers can be used in mathematics instruction, involving cutting numbers and shapes for a variety of purposes and collecting and analyzing information, are presented and illustrated. (MNS)

Considerations of the history of similar techniques and the structure of the method itself are used to discuss this question. (MP)
