The University of Arizona - Institute for Mathematics & Education The Common Core State Standards in mathematics were built on progressions: narrative documents describing the progression of a topic across a number of grade levels, informed both by research on children's cognitive development and by the logical structure of mathematics. These documents were spliced together and then sliced into grade level standards. From that point on the work focused on refining and revising the grade level standards. Spell and Summon This card curiosity is attributed to Lewis Carroll. Lay down eight cards with these values: Now add the values in each column, find a card of that value in the deck, and place it on top of the lower card. Aces count as 1, jacks as 11, queens as 12, and kings as 13. Thus in the first column 1 + 2 = 3, so you’d place a 3 on top of the 2.
Weierstrass functions Weierstrass functions are famous for being continuous everywhere, but differentiable "nowhere". Here is an example of one: It is not hard to show that this series converges for all x. Math Playground Math Games - Number Puzzles - Problem Solving advertisement Grade 1 Grade 2 Grade 3
Curriki - Open Educational Resources Traditionally one of the loathsome subjects, math is often a stumbling block for students. Curriki’s Project-Based Learning (PBL), Common Core Aligned Geometry curriculum will help your students build the skills and confidence that will help them conquer any mathematical problem and develop 21st century skills such as communication, collaboration, and teamwork. And they’ll love coming to geometry class! Evaluating Technology Use in the Classroom Evaluating the use of technology in a classroom environment is not something most administrators are trained to do. It is easy to walk into a classroom and see that every student is using a computer, but how do you really assess if and what type of learning is taking place? In the past, I have had administrators tell me “I walked into the teacher’s room and all the students were on laptops.” As though just the site of students working on laptops meant they were engaged in the learning process. I have been trying to wrap my head around a simple way for administrators to evaluate the use of technology in the classroom (a thank you to Dennis Harter who got me thinking about this). When most administrators evaluate teachers during the evaluation process, they have some sort of check sheet they are working from either mental or as part of a school’s evaluation process.
Blog : The Incredible Convenience of Mathematica Image Processing It’s been possible since Version 6 of Mathematica to embed images directly into lines of code, allowing such stupid code tricks as expanding a polynomial of plots. But is this really good for anything? As with many extremely nifty technologies, this feature of Mathematica had to wait a while before the killer app for it was discovered. Triangle Dissection Paradox The above two figures are rearrangements of each other, with the corresponding triangles and polyominoes having the same areas. Nevertheless, the bottom figure has an area one unit larger than the top figure (as indicated by the grid square containing the dot). The source of this apparent paradox is that the "hypotenuse" of the overall "triangle" is not a straight line, but consists of two broken segments. As a result, the "hypotenuse" of the top figure is slightly bent in, whereas the "hypotenuse" of the bottom figure is slightly bent out.
New Jersey Student Learning Standards New Jersey Student Learning Standards In 1996, the New Jersey State Board of Education adopted the state's first set of academic standards called the Core Curriculum Content Standards. The standards described what students should know and be able to do upon completion of a thirteen-year public school education. Over the last twenty years, New Jersey's academic standards have laid the foundation for local district curricula that is used by teachers in their daily lesson plans. The Socratic Method The Socratic Method:Teaching by Asking Instead of by Tellingby Rick Garlikov The following is a transcript of a teaching experiment, using the Socratic method, with a regular third grade class in a suburban elementary school. I present my perspective and views on the session, and on the Socratic method as a teaching tool, following the transcript. The class was conducted on a Friday afternoon beginning at 1:30, late in May, with about two weeks left in the school year.
Command-line interface Command-line interfaces to computer operating systems are less widely used by casual computer users, who favor graphical user interfaces. Command-line interfaces are often preferred by more advanced computer users, as they often provide a more concise and powerful means to control a program or operating system. Programs with command-line interfaces are generally easier to automate via scripting. Tips & Tricks SMART Training This is our new 21st Century learner... wow!
