Procedures and results of a study involving ability grouping procedures in elementary school mathematics classes are reported. The investigators recommend that within-class ability grouping is practical in departmentalized mathematics classes. (JG)

Attribute blocks are described, with suggestions for developing sets of attribute materials. Various activities and games are described and illustrated. (MNS)

Ten activities classifying buttons are presented. Additional suggestions are given for using children's literature and for how to begin. (MNS)

Described are activities using jar lids for sorting, classifying, and graphing; ordering; and measuring circumference and diameter. (MNS)

Describes an approach which helps sixth-grade students become excited about word problems. By using the approach (which involves categorizing a problem before solving it), students master skills in the problem and also develop more positive attitudes toward solving problems. The approach is equally applicable to any intermediate/junior high grade…

Described are integrated science and mathematics activities that focus on gathering, displaying, and interpreting data on balloons. Students are involved in sampling, taking polls and surveys, doing experiments, classifying, estimating, and measuring. Included are directions, extensions, and activity sheets for students and parents. (KR)

Describes an activity in which students utilize mathematical communication and reasoning skills to develop a class constitution. Students brainstorm rules for their classroom in cooperative-learning groups, classify them into categories, and justify their decision to the class. (MDH)

Presented are activities that focus on gathering, using, and interpreting data about fingerprints as a basis for integrating mathematics and science. Patterns, classification, logical reasoning, and mathematical relationships are explored by making graphs, classifying fingerprints, and matching identical fingerprints. A parent-involvement activity…
