Standards for Mathematical Practice "Does this make sense?" Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary.

Announcing a New Education Widget: GeoGebra! Math teachers rejoice: one of your favorite online tools now comes embedded right in your Wikispaces page! We’re very pleased to announce a new Widget available in the Education Gallery: GeoGebra. GeoGebra is a free, multi-platform online tool that allows students to visualize mathematical concepts. Fun Kids Online Math Games "Sheppard offers everything from early math to pre-algebra. The lessons include interactive activities to practice concepts. Students can shoot fruit, pop balloons, and even play math man (the math version of pac man!). Fractions, place value, money, and basic operations are some of the areas that are covered.

Model Curriculum: Mathematics (K-12) Mathematics (K-12) REVISED Model Curriculum – June 2014 The model curriculum is intended as a tool to support districts in their own curricular planning. During its development, teams of educators used all available information about the Common Core State Standards and PARCC to appropriately organize and sequence the standards across five units.

One-time Pad Cipher The one-time pad is a long sequence of random letters. These letters are combined with the plaintext message to produce the ciphertext. To decipher the message, a person must have a copy of the one-time pad to reverse the process. A one-time pad should be used only once (hence the name) and then destroyed. This is the first and only encryption algorithm that has been proven to be unbreakable. Graphing Calculator Untitled Graph Create AccountorSign In π for Education: Google Classroom: Introduction Google Classroom helps teachers create, assign, and collect student classwork and homework paperlessly. With Google Classroom, teachers can seamlessly integrate Google Docs, Google Drive, and Gmail to create assignments, provide feedback for in progress and completed work, and communicate with their students directly and with whole class announcements--all without using a single piece of paper. Students can work on assignments in Google Docs and turn it in with a few clicks. When teachers create assignments, folders are automatically created in Google Drive for each student. They can choose to share a single document (like project instructions), or automatically make a copy for each student (like a project template).

Brain Teasers Sliding Triangle The triangle at left lies on a flat surface and is pushed at the top vertex. The length of the congruent sides does not change, but the angle between the two congruent sides will increase, and the base will stretch. Initially, the area of the triangle will increase, but eventually the area will decrease, continuing until the triangle collapses. What is the maximum area achieved during this process? And, what is the length of the base when this process is used to create a different triangle whose area is the same as the triangle above?

Factorization of Quadratic Expressions with Negative Coefficients ( Read ) What if you had a quadratic expression like or in which some or all the coefficients were negative? How could you factor that expression? After completing this Concept, you'll be able to factor quadratic expressions like these for various negative coefficient values. Watch This
