A game based on "skittles" can provide practice on basic facts. (SD)

Several bicentennial games and puzzles, all using the number 1776, are 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)

Outlined is the preparation and use of graph paper for activities in counting' approximation, making bar graphs, and decimals. (MP)

Children ranging in age from three to six years counted 7, 10, and 14 items arranged in columns or in rows. Developmental changes in the spatial strategy and the relation of strategy to accuracy were examined. (JMB)

Parents should stop teaching preschoolers to say "one, two, three, four" and challenge them to see and think groups. School administrators, teachers, teachers of teachers, and textbook writers should pitch that number line in the trash and allow students to learn how to learn by thinking groups. (Author/JC)

The role of mental age (MA) and visual-perceptual ability in number concept development was examined with 48 nonretarded and retarded children from regular school settings. (Author)

Twenty nonconserving retarded adults were assigned to equated training and control groups (n=10 in each group). (Author)

A six-step method of teaching subtraction by renaming is presented, using money as the learning vehicle. (MP)

Greatest common factor and least common multiple are the concepts used to play this game that has football as its basis. Rules and examples are given. (MP)

The operation of rounding is shown to lead into an investigation of an abstract mathematical system. Properties of the system are discussed and graphs of the rounding function are drawn. Some questions for discussion are given. (MP)

Computer programs for solving alphametics are discussed. A fortran program for solving a general additive alphametic is given. (MP)

A broad definition of numeracy is suggested that involves the use of mathematical knowledge. (MP)

A computer program is given that will guess any number between 1 and 1,000,000 in no more than 20 guesses. Suggestions and materials for related instruction are included. (MP)
