"Pure Mathematics Project Ideas"

" to design and develop well-engineered assessment tools to support US schools in implementing the Common Core State Standards for Mathematics (CCSS). Tools for formative and summative assessment that make knowledge and reasoning visible, and help teachers to guide students in how to improve, and monitor their progress. These tools comprise: * Lesson Units for Formative Assessment: some focused on math concepts, others on non-routine problem solving - 20 per grade for Grades 7-12. * Professional Development Modules: to help teachers with the new pedagogical challenges that formative assessment presents. * Summative Assessment Task Collection: to illustrate the range of performance goals required by CCSS. * Prototype Summative Tests: designed to help teachers and students monitor their progress, these tests provide a model for examinations that may replace or complement current US tests."

To define a function: f = (x,y) -> x^2 + y^2 To evaluate: show f(3,4). If you exclude the arguments: show f you get: *function (x, y) { return add(pow(x, 2), pow(y, 2)); }*. That's really cool.* *Provides a great way to discuss functions both mathematically and computationally.

" include some categories as well as individual sites which gives me the excuse to mention far more than 10! Note that every site mentioned here is free to use."

Concept of Whole Numbers in Arithmetic and know the purpose of whole numbers and understand how to use them in mathematics and also know the method of representing the whole numbers in mathematical language.

The Albert Einstein Distinguished Educator Fellowship Program is now accepting applications for the 2013-2014 Fellowship Year. The Einstein Fellowship Program is available to current K-12 science, technology, engineering, and mathematics (STEM) educators with a demonstrated excellence in teaching and leadership.

"ScienceEducation.gov connects teachers and students to free, federally-funded Science, Technology, Engineering, and Mathematics (STEM) education resources."

"Engineering: An Introduction for High School is an open-source high school "flexbook" created using software developed by the CK-12 Foundation by engineering and education faculty at Arizona State University. The flexbook format allows the book to be customized for multiple audiences. The text can be updated, expanded, and repurposed as necessary to support specific standards and classroom needs. The current draft has four content chapters that cover the nature of engineering, engineering and society, engineering design, and the connection between engineering, science, and mathematics."

"Take a Spin on the Centrifuge (MIT Engineering K-12 Video Pilot) This video uses Man-Vehicle Lab's human centrifuge to discuss centripetal force and countermeasures for astronaut bone and muscle loss in space. It shows the mathematics required to calculate centripetal force, and performs an experiment on the centrifuge with an "astronaut.""

"Project Lead The Way (PLTW) is the leading provider of rigorous and innovative Science, Technology, Engineering, and Mathematics (STEM) education curricular programs used in middle and high schools across the U.S."

"PhysWiki is one of seven integral components of the STEMWiki Dynamic Textbook Project (DTP), a multi-institutional collaborative venture to develop the next generation of open-access textbooks to improve STEM education (science, technology, engineering and mathematics) at all levels of higher learning. The central aim of the DTP is to develop and disseminate free, virtual, customizable textbooks that will substitute for current, commercial paper texts"

"The Central Florida Aerospace Academy exists to provide a meaningful and content rich education that will inspire and motivate students at all levels. Students are challenged to reach high levels of achievement in science, technology, engineering and mathematics in preparation for high-tech careers in the fields of aviation and aerospace."

"JoVE Bioengineering focuses on techniques in which the principles of engineering, mathematics and physics are applied to problems associated with the life sciences."

"Portals → Technology → Engineering - The Engineering Portal Engineering is the application of science, technology, mathematics, art, and practical experience to the design and production of objects, tools or processes."
