Teachers asked students to write down as many names for their favorite numbers as they could. The results were surprising, with many students performing better than their teachers had expected. (SD)

Mathematical concepts and experiences are recalled and organized in a flow chart format. The power of unifying ideas in mathematics often causes this sequence to be forgotten or assigned less importance than it should be. (SD)

Games and activities, which are fun, practical, and related to the child's world, are presented. Suggestions are given for building skills in estimating lengths, guessing how many, recognizing patterns in counting, multiplying with "waffles," classifying by attributes, and adding and subtracting with special cards, relays, and play…

A game similar to Nim is described. Students in grades three through six have played the game in conjunction with the study of modular arithmetic,and have been able to develop winning strategies. (SD)

Vertical scales of numbers in ascending order can be used to teach addition, subtraction, multiplication and division processes to mentally retarded students. (CL)

This booklet provides worksheets for children in preschool through grade one. The focus is on developing number concepts, with activities on matching numbers with pictures and on completing sequences, addition and subtraction facts, measurement ideas, fraction ideas, and identifying shapes. (MNS)

Because second grade students had difficulty in explaining what they knew about the number 15, it was suspected that they did not understand place value. Realizing every number has a place value and its place provides facility for calculation, a teacher attempted to ascertain second grade students' (N=18) knowledge of place value. Results of…

Nine problem situations involving the use of random numbers are given. Topics include cooking, hunting, bacteria contamination, waiting lines, ransom walks, and branching. In addition to the problem situation, questions are suggested which can be used to extend the investigations. (LS)

This is a supplementary unit to Mathematics for High School, Intermediate Mathematics, Part 1. In this publication, real numbers and rules for operating them are examined. The study begins by examining whole numbers and some of the properties of addition and multiplication of whole numbers. Most of the basic rules for algebra are developed from…

Worksheets for a short unit on magic squares, together with directions for their use and answer keys, are provided. They are suggested for use in grades seven through twelve. (SD)

Children were grouped according to ability to conserve number and then randomly assigned to training on arithmetic concepts or playing a game. The research hypothesis that there would be an interaction effect between conservation and effect of treatment was not confirmed. (SD)
