This article describes a series of activities and worksheets to provide students with experience in graphing number pairs. Students at different lev els can use the activities to relate basic arithmetical operations to graphs. (Worksheets are included.) (SD)

Children at many levels enjoy using spinners to explore probabilities and practice predicting, tabulating and graphing outcomes, and observing results. Directions for making spinners, descriptions of several activities, and sample worksheets are provided. (SD)

Four activities and related worksheets are provided. The activities, all concerned with multiplication, are directed toward students at different levels, and deal with repeated addition, basic facts, and factorization. (SD)

The letters of the alphabet can be classified according to their geometric and topological characteristics on these worksheets. An additional worksheet provides for tallying the frequency of usage of the letters in three sentences. (SD)

Activities related to the place value system of numeration and regrouping decimal expressions are described. Worksheets are provided. (SD)

The use of clocks and time concepts is the theme for several activities involving graphing and arithmetic computation. (SD)

Activities for reinforcement of whole number operations are provided through games that present strategic situations for children to use their computation skills. (JP)

Worksheets are provided for activities involving associating numbers with letters (as on the telephone dial) to compute values for words. Other activities involve systematic counting of telephone numbers. (SD)

Worksheets are provided for activities involving estimation and determination of areas, perimeters and volumes. The units of measure are centimeters, square centimeters and cubic centimeters. (SD)

This set of worksheets provides exercises related to making change, spending a fixed amount of money by "buying" items at listed prices, and deciding which of two quantities of coins has greater value. (SD)

Several activities are described for students at different elementary grade levels. Some involve estimation of quantities, and others include reasoning about permutations and combinations. (SD)

Completing these worksheets leads students to discover patterns in the distribution of even numbers and numbers obtained by successive additions of 9 (primary grades). Worksheets for intermediate grades involve counting the number of factorizations for integers, and addition of the first nine whole numbers. (SD)

Using these worksheets students explore patterns in numerical and geometric processes, and predict the outcomes when the processes are iterated further. (SD)
