Mathematics for the Elementary School, Unit 15, Addition and Linear Translations.
Clark, Julia, Ed.; Myers, Donald E., Ed.
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 unit introduces the concept of a ray and uses it to develop addition and subtraction on a number line by directed segments. There are also exercises leading to the concept of place value and work with modular arithmetic. Geometric concepts are explored through examining scales on intersecting and parallel lines. Worksheets and commentaries to the teacher are provided and additional activities are suggested. (JP)
