Mangahigh.com - Play maths, love maths Experimenting with the Mastery Flip.. In the fall of 2011, I piloted 1 class with the flip classroom. In January of 2012, I decided to roll it out with all four sections of 8th grade science and not only that (at this point, I must have lost my mind), I decided to try to the mastery flip technique. I am not going to lie, I spent most if not all of my Christmas break in 2011 assembling the pieces of trial run. Since my school district is not 1 to 1, I had to be creative and design a way that could work for my classroom. I was able to sign a laptop cart out for every Monday and Friday during the course of the unit. On the Friday, students chose how they wanted to demonstrate what they understood from the week. The mastery project was something students would continually come back to throughout the course of the unit and use it to extend their learning around a singular topic area that they would keep stretching and learning about. However, it wasn't all roses.
Math_Johnson: My wife's first #flipclass... Music Math Harmony -- Math Fun Facts It is a remarkable(!) coincidence that 27/12 is very close to 3/2. Why? Harmony occurs in music when two pitches vibrate at frequencies in small integer ratios. For instance, the notes of middle C and high C sound good together (concordant) because the latter has TWICE the frequency of the former. Well, almost! In the 16th century the popular method for tuning a piano was to a just-toned scale. So, the equal-tempered scale (in common use today), popularized by Bach, sets out to "even out" the badness by making the frequency ratios the same between all 12 notes of the chromatic scale (the white and the black keys on a piano). So to divide the ratio 2:1 from high C to middle C into 12 equal parts, we need to make the ratios between successive note frequencies 21/12:1. What a harmonious coincidence! The Math Behind the Fact: It is possible that our octave might be divided into something other than 12 equal parts if the above coincidence were not true!

Edcamp Leadership: Flipping the Faculty Meeting | Apace of Change Edcamp Leadership marked my entrance into the world of Edcamps this month, both as an attendee and an organizer. I have known most of the key players in the Edcamp Foundation for many years through traveling in the same educational circles in social media, so knowing the kinds of educators they are, it really didn’t surprise me that a) I had a blast, and b) so many attendees enjoyed it as well. I suppose the true measure of how effective it was or was not will be determined by which of the many ideas discussed actually get implemented and lead to some improvement in the attendee’s schools. In the meantime, however, what I want to record here are my thoughts on the organizational process, the session I ran that morning, and some general overall takeaways from the day. Although I specifically asked about obstacles to flipping faculty meetings, most participants only brought them up along with ideas for how to get around them.
Odd Numbers in Pascal's Triangle -- Math Fun Facts Pascal's Triangle has many surprising patterns and properties. For instance, we can ask: "how many odd numbers are in row N of Pascal's Triangle?" For rows 0, 1, ..., 20, we count: row N: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 odd #s: 1 2 2 4 2 4 4 8 2 4 04 08 04 08 08 16 02 04 04 08 04 It appears the answer is always a power of 2. THEOREM: The number of odd entries in row N of Pascal's Triangle is 2 raised to the number of 1's in the binary expansion of N. Presentation Suggestions: Prior to the class, have the students try to discover the pattern for themselves, either in HW or in group investigation. The Math Behind the Fact: Our proof makes use of the binomial theorem and modular arithmetic. (1+x)N = SUMk=0 to N (N CHOOSE k) xk. If we reduce the coefficients mod 2, then it's easy to show by induction on N that for N >= 0, (1+x)2^N = (1+x2^N) [mod 2]. Thus: (1+x)10 = (1+x)8 (1+x)2 = (1+x8)(1+x2) = 1 + x2 + x8 + x10 [mod 2]. (1+x)11 = (1+x8)(1+x2)(1+x1) [mod 2]
Flipped Classroom A New Learning Revolution There has been a growing buzz around a recently coined phrase " Flipped Classroom". This term starts to take root in education as more and more educators are discovering it. So what is this all about and what are its advantages in learning and teaching? Flipped Classroom is an inverted method of instruction where teaching and learning take place online outside of the class while homework is done in the classroom. Flipped Classroom shifts the learning responsibility and ownership from the teacher's hands into the students'. Flipped Classroom depends a lot on educational technology and web 2.0 tools such as podcasting and screencasting applications. "In most Flipped Classrooms, there is an active and intentional transfer of some of the information delivery to outside of the classroom with the goal of freeing up time to make better use of the face-to-face interaction in school. A direct and concrete example of Flipped Classroom concept is the popular Khan Academy.
The Collaborative Lecture: A Hybrid Approach to Learning As educators, we have often been led to believe that lecturing is “bad”, and it’s easy to see why. Just ask your students. They often complain of the many hours they have spent slavishly copying text from the screen directly to their notebook. And, to be honest, this practice hasn’t changed dramatically from Age of the Overhead Projector to the Epoch of PowerPoint (Generation). There have been countless critiques of PowerPoint and the “cognitive style” it propagates with its built-in templates and slide layouts. The tool I usually employ is VoiceThread, which offers either a free or paid version, and allows students to either type their comments, leave pen-like annotations, as well as record their voice or their webcam. Spiro Bolos is an 18-year veteran of the classroom, having taught a wide range of courses in Social Studies at New Trier High School.
Sums of Two Squares Ways -- Math Fun Facts In the Fun Fact Sums of Two Squares, we've seen which numbers can be written as the sum of two squares. For instance, 11 cannot, but 13 can (as 32+22). A related question, with a surprising answer, is: on average, how many ways can a number can be written as the sum of two squares? We should clarify what we mean by average. So if A(N) is the average of the numbers W(1), W(2), ..., W(N), then A(N) is the average number of ways the first N numbers can be written as the sum of two squares. A surprising fact is that this limit exists, and it is Pi! Presentation Suggestions: This might be presented after a discussion of lattice points in Pick's Theorem. The Math Behind the Fact: The proof is as neat as the result! Therefore, the sum of W(1) through W(N) counts the number of lattice points in the plane inside or on a circle of radius Sqrt(N) (except for the origin), and the average A(N) is this number of lattice points divided by N.
