The focus is on suggestions for teaching rounding wisely as an estimation strategy. (MNS)

Comments on the history of negative numbers, some methods that can be used to introduce the multiplication of negative numbers to students, and an explanation of why the product of two negative numbers is a positive number are included. (MNS)

Practice in adding single digits is provided by puzzles called Totalines. The Magic Pentagram and Hexagram and the Distance Chart extend the addition practice. (MNS)

A collection of games and puzzles that teachers can use to replace or supplement the usual textbook subtraction examples involving large numbers is given. Most of the nine activities are self-checking. (MNS)

Ways in which classroom calculators enriched, supplemented, supported, and motivated the regular sixth-grade mathematics program are discussed. (DT)

A game with dice that can be adapted for use at various levels of understanding is presented. (MS)

"Capture" is a game that requires players to perform several computations on each turn and to choose an optimal move, thus promoting higher-order thinking and probability notions. Rules are given, playing is described, and extension activities are noted. (MNS)

A finger method for subtraction that has proved successful with many young subtraction-troubled mathematics students is presented. (MP)

Ways elementary school teachers might use calculators to help students are noted. A total of nine activities, listed under place value, computation, and estimation, are provided to assist the classroom instructor in effectively employing calculators. (MP)

A game designed as a take-off on tenpin bowling is described which allows children to review all four operations while playing. Three dice are rolled and a pin is knocked down when numbers can be combined to the value of that pin position. Scoring is similar to standard bowling. (MP)

Mathematics instruction can be approached as a cognitive skill, as illustrated by these elementary-level classroom activities. (LH)

Solutions to difficult equations are illustrated with numerical techniques that can be used easily on calculators. Flowcharts and programs for computers and calculators are included. (MP)

Four categories of abuses are discussed: calculations, games and puzzles; mystical button pushing; and checking answers. Useful activities are illustrated for the categories of calculations, patterns, exploration, applications, and new content. (MP)

Describes the incorporation of math concepts into snacktime for prekindergarten students through a self-serve center with a snack menu. Children gain experience in counting, sequencing, and measuring continuous quantities; understand the concepts of sets, uniform units, more and less, equal quantities, fractions, zero, and patterns. (KB)

Describes an activity for computing the volume of water in a blanket of snow, focusing on measuring and controlling variables, and then using critical thinking skills to analyze data. (HTH)
