Activities involving set union and intersection, graphing solutions of open sentences, and negation are described. These activities afford students with opportunities for computational practice as well as instruction on equations and inequalities. (SD)

This booklet was written to provide role models for young people. Included are stories of 13 interesting women who have worked in careers that require substantial training in mathematics, with the hope of encouraging students to aspire to careers in fields using mathematics. Both contemporary and noncontemporary women are included to provide…

Intended for teachers of learning disabled children, the performance based learning package provides a list of steps for students to take toward obtaining competency in time and time telling. The package is broken down into eight milestones which include such steps as constructing a simple sundial as a group project, understanding that 15 minutes…

This pamphlet recommends that elementary-school teachers be provided with inservice courses which deal with probability concepts. The recommendations are based on the experiences of 120 teachers who taught probability in elementary school as part of a project of the National Science Foundation. The authors observe that probability is important…

Using a great variety of word problems drawn from many contexts can make multiplication and division rules more relevant to the student's needs. (SD)

The algorithms for finding cube roots is approached by slicing a cube. (SD)

Similar rectangles are the basis of a set of activities using newspaper. Topics arising include infinite series and Pythagorean theorem. (MP)

Discovering 3 by 3 magic squares, using numbers 1 through 9, is presented as a learning activity on three different levels. (MP)

These worksheets deal with sums of numbers. Students are asked to find the relationship between the last number in the series, the number of addends, and the sum. (MP)

Four articles are presented in this monthly column: dealing effectively with metric conversions; teaching how to round numbers; why a false statement implying a false statement is true--a discovery explanation; and a third-grade puzzle with interesting implications. (MP)

Topics covered include: a game involving dice, using curve stitching to teach number concepts, and an activity to introduce rectangular coordinate systems. (MP)

Instructional sequences are presented for teaching two-digit multiplication and division with one- and two-digit divisors using a base-oriented approach. (MN)

Four games that reinforce the concepts of place value and ordering numbers are described. (JT)

A game for two teams employs dice, meter sticks, and Cuisenaire rods. The game gives practice in number facts, regrouping, and use of rods; it can also serve as an introduction to the metric system. (SD)

Games which use dominoes, dice, and playing cards to promote computational skill are described. (SD)
