Presented are worksheets designed to be duplicated and used in the classroom. Included are sheets for three levels: (a) grades 1-3, addition drill using a dot puzzle; (b) grades 4-6, multiplication drill using a cross-number puzzle; (c) grades 6-8, practice with fractions using a number grid. (RS)

Presents worksheets on geometric concepts for use in the mathematics classroom: congruent polygons (grades 1-8), polygons and edges of solid figures (3-8), and surface area of prisms (5-8). (RS)

Activities designed for levels 1-4 give experience in recognizing shape and form after standard transformations are applied to geometric figures. The activities for the upper levels use a physical projection to provide experience with the properties of similarity. (DT)

Worksheets for the lower grades use the number line to relate basic units of measure within the metric system. Upper level activities use the number line to relate English units and metric units. (DT)

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

Worksheets for the lower grades involve locating numbers on the number line; the activities for the upper levels focus on the estimation of sums and products. (DT)

Presented are two self-contained worksheets and teacher guides for open-ended experiences in recording and reading data which require the use of basic addition facts. One is for grades 1-3; the other for grades 4-8. (CT)

Worksheets utilize a paper geoboard to provide a variety of experiences with basic geometric concepts. (JP)

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)

Worksheets are provided which use basic geometric forms as a vehicle for student discovery of efficient counting procedures and of counting patterns. (DT)

Mathematical worksheets are presented for use in the elementary school classroom. The sheets deal with arithmetic and number patterns, one being for the primary grades, the other for grades 4 to 8. (RS)

The theme for the column is composing and solving problems. One section has teacher-developed problems for the primary grades. The other section contains student-authored problems for the upper grades, submitted for a student problem contest. (LS)

Included are worksheets on visualization of three dimensions for use in the classroom. The activities include: counting cubes in an arrangement (grades 1-3), constructing a cube with paper (4-6), and visualizing a large cube constructed with smaller cubes (6-8). (RS)

The focus of these worksheets is on problem solving. Verbal problems involving number concepts are presented for primary levels; worksheets for the intermediate grades draw on geometric concepts, measurement, and elementary logic. (DT)

Worksheets provide activities with a modified number line and involve ordering numbers, number facts, and estimation. A suggestion for a bulletin board display is included. Two problem posters are also provided. (DT)
