Described is a bingo-like game for classroom drill with fractions and their equivalents. (RS)

Included are two curriculum guides, Section D and Section E, which continue instruction of the three guides in SE 012 723. Counting (by ones, by twos, by threes, ..., by twelves) is extended to 144 in Section D and to 1000 in Section E. The creation and manipulation of more complex equations are taught, including the notion of substitution. The…

Students use a spinner device to generate numbers, which they then insert into given open sentences and search for true statements. (MM)

This guide continues instruction of the three guides in SE 012 723 and of the two guides included in SE 012 724. Counting skills, appreciation of pattern and order, and understanding of place value are extended to numbers up to one million, and the associative, commutative and distributive laws are made explicit. Manipulation of equations is…

The column presents activities for grades K-8 focusing on the concept of equality. A geometric-puzzle motif is used, with basic number facts reviewed for the lower grades and equivalent fractions for the upper levels. Four worksheets and a problem poster are included. (DT)

One chapter of the fifth unit in this SMSG series for the general mathematics student covers the topics of writing equations, solving linear equations, using graphs to solve equations, inequalities, and solving inequalities. The second chapter discusses ratios and percents, decimal notation, decimal representation for rational numbers, rounding…

Specific mathematics lab activities involving fractions and measurement at the seventh grade level are described. (DT)

Worksheets on 3 x 3 magic squares are provided: one emphasizes recognition of results when a square is flipped or rotated; the other two give practice in computation with whole numbers, fractions, decimals, and integers. (DT)

This monograph focuses upon the teaching of fractional concepts. The introduction to fractional concepts is treated through sets, number lines, and area. Included are three diagnostic pretests, one of which can be administered to a nonreader. The major core of the monograph consists of 23 worksheets which can be removed for duplication. The…

The purpose of the study was to examine the effect of instruction using Dienes' perceptual variability principles on primitive generalization and mathematical generalization. The following was studied: the effect of achievement-to-criterion on one, two, or three non-symbolic embodiments of an objective using a selected class of variables on the…

The purpose of the study was to examine the effect of instruction using Dienes' perceptual variability principle on the development of ability to operate with symbols in a meaningful way. The following was studied: whether an increase in the number of enactive and/or iconic embodiments of a concept utilized in an instructional episode will produce…
