The history of mental computation in the elementary school curriculum is briefly described, followed by discussion of the benefits of mental computation. How thinking skills are enhanced is then illustrated. (MNS)

Use of compatible numbers resulting in easy mental computations is described, along with related teaching and testing tips. (MNS)

Activities on estimation and mental computation are presented. Patterns on a hundred chart, an amazing fact, teaching and testing tips, and other references are included. (MNS)

Four worksheets and teaching suggestions are presented, with the focus on mental computation for levels 2-3; factors, levels 3-4; and nonroutine problems, levels 5-6 and 7-8. (MNS)

Four activities focus on estimation and mental computation. Each consists of a game that can be used on an overhead projector. The content involved finding costs and estimating sums, products, and percents. (MNS)

Describes the method to solve problems called T-E-M-T-T: trial, error, and modified trial through technology. The method integrates students' skills of estimation, mental computation, and appropriate choice of calculator use. Includes 2 activities for each of grades K-4 and 5-8 that illustrate the method. (MDH)

Presents five activities focusing on mental computation and estimation for the K-3, 3-5, 4-6, and 6-8 grade levels that require the student, acting as a judge, to review solutions to problems and to pronounce and justify a verdict. Provides suggested materials, questions, possible extensions, answers, and worksheets for each activity. (MDH)

Front-end estimation is discussed, with several examples, teaching tips, testing tips, and some references on research and additional activities. (MNS)

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

Ideas are given on how to teach children to make estimates in measurement. (MNS)

Presented are activities which give practice in making estimates, gathering data, and checking the reasonableness of results. (TG)

Presents five examples of how technology can be integrated into Family Math nights. Activities involve graphing, managing money, developing mental mathematics skills, developing deductive and spatial reasoning, and using tangrams to explore patterns and spatial relationships. Includes a list of software publishers. (MDH)
