The Importance Of Using Manipulatives In Teaching Math Today, Joseph M. Furner, Nancy L. Worrell

Transformations

This paper explores the research and use of mathematics manipulatives in the teaching of mathematics today during an age of technology and standardized testing. It looks at the drawbacks and cautions educators as they use math manipulatives in their instruction. It also explores some cognitive concerns as a teacher goes about teaching with math manipulatives. The paper shares many commonly used math manipulatives used in today’s classrooms and matches them up to some of the Common Core Math Standards that are taught today in classrooms in the USA and around the world.

G96-1291 Housing For Horses Flooring For Stalls, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses various types of flooring for use in horse stalls.

Stalled horses require much greater care, attention and labor. The availability of optimal ventilation with fresh clean air circulation is essential to healthy horses. Adequate ventilation reduces the presence of air contaminants such as dust, molds and irritating gases from decomposing manure.

Materials used for stall floors can greatly influence air quality, ease of stall maintenance and manure removal. Stall floors must be made of durable material which is not slippery, yet is absorbent, easy to clean, and resistant to pawing. Whatever the materials used, floors should require …

G83-683 Quality Concrete For Swine Facilities, David P. Shelton, Gerald R. Bodman, Thomas A. Silletto

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the major items to consider when using concrete for swine facilities to help assure that quality concrete is obtained.

Concrete is widely used to construct swine production facilities. Versatility, durability, and relatively low cost are characteristics that make it ideally suited for floors, walls, foundations, pen dividers, and manure storage structures. With appropriate design, concrete can even be used for the building roof and feeders. There are, however, certain major items to consider to help assure quality concrete and years of reliable service regardless of the specific use.

G82-623 An Overview Of Concrete As A Building Material, David P. Shelton, James M. Harper

University of Nebraska-Lincoln Extension: Historical Materials

The general properties of concrete are discussed, as well as its components and their proportions. Includes decisions customers should consider before using concrete.

Concrete, specifically portland cement concrete, has the qualities of strength, durability, versatility, and economy, and can be placed or molded into virtually any shape and reproduce any surface texture. It is the most widely used construction material in the world. In the United States almost twice as much portland cement concrete is used as all other construction materials combined.

G73-31 Design And Construction Of Grain Bin Floors (Revised May 1979), Gerald R. Bodman, Thomas L. Thompson

University of Nebraska-Lincoln Extension: Historical Materials

The foundation and floor for a new or used grain bin performs several functions. In addition to supporting the grain and the bin, it protects the grain from moisture and rodents, prevents settlement of the bin, and anchors the bin. Good design and careful construction are necessary to assure that the bin will perform in a satisfactory manner. For efficient operation, a bin floor must be capable of serving as an integrated part of the total grain handling system.

Ec32-713 The Trench Silo In Nebraska, Ivan D. Wood, E.B. Lewis

University of Nebraska-Lincoln Extension: Historical Materials

The original idea of using a trench for the storing of ensilage seems to have been the outgrowth of the practice long used in several European countries of storing clover and beet tops in pits. Shortly after the World War, western Canada followed by Montana and North Dakota began to use the trench silo. In Nebraska the true trench silo made its appearance about 1925 or 1926.

The trench silo as described in this circular, unless lined with some permanent material such as brick, concrete or stone, must be considered a temporary structure which will serve for a few years …
