Mathematics for the Elementary School, Unit 4, Sets, Numbers, Numerals.
Powell, Bonnie, Ed.; And Others
The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and reinforce the other where appropriate, with common techniques and concepts being sought and exploited. Content is presented in story fashion. The stories serve to introduce concepts and lead to activities. Imbedded in the pictures that accompany the stories are examples of the concepts presented. This booklet contains a unit on numbers and set concepts. The topics include representing numbers by constructing or describing equivalent sets, using words to represent numbers and using special written symbols to represent numbers. Some of the activities are designed for using the "Minnebars," in which the length of a bar represents a number. Although the formal introduction of addition does not occur until Unit 7, the Minnebar activities serve as pre-addition exercises. Union and intersection of sets are also introduced in this unit. Worksheets and commentaries to the teacher are provided and additional activities are suggested. (JP)
