What is a Rational Number

What is a Rational Number A rational number is a number which has a numerator and a denominator. Rational numbers are also called as fractions and in some cases they can also be described as a part of the whole. Generally rational numbers are represented in a/b form where a and b are any integers except b 0. If the number in the denominator is 0, then the rational number becomes undefined and is no more called a rational number. In some cases rational numbers can be simplified further as well. Example 1: Add the given two rational numbers: 4/7+ 3/7. Given expression: 4/7+ 3/7 Here both 4/7 and 3/7 are fractions and they are being added together. In order to add or subtract two fractions, we have to make sure that the fractions have the same denominator. Both 4/7 and 3/7 have the same denominator 7, hence they can be added directly! This gives: 4/7+ 3/7= (4+ 3)/= 7/7. 7/7 can be simplified by dividing the top and the bottom by the factor 7-7/7= 1/1 Therefore, 4/7+ 3/7= 1/1= 1. Example 2: Multiply the given two rational numbers, (3/5) * (4/6) Given rational numbers: (3/5) * (4/6) Now in order to multiply the given two rational numbers, we multiply the numbers in the numerators together and the numbers in the denominators together. This gives: (3/5) * (4/6) = (3 * 4)/ (5 * 6) = 12/30 Now we can simplify 12/30 by dividing the top and the bottom with their common factor 6- 12/30 = 2/5 Hence we get: (3/5) * (4/6) = 2/5.

What to Know About the Updated SAT Suite of Assessments

What to Know About the Updated SAT Suite of Assessments The SAT, a standardized test commonly used as a measure for college admissions, has undergone many changes since its inception in 1926. Its most recent update has been its transformation to the SATSuite of Assessments, which includes four tests that span middle and high school. Regardless of your grade level, and if youve already taken an older version of the exam, heres what you need to know about the updated SAT Suite of Assessments: New tests in theSAT Suite of Assessments In addition to the already established SATand PSAT/NMSQT (National Merit Scholarship Qualifying Test), the Suite now includesthe PSAT8/9 and PSAT 10. As their names suggest, the PSAT 8/9 is intended to be taken in the fall or spring of eighth and ninth grade as a foundation for college readiness and the PSAT 10 can be taken in the spring of tenth grade, a check-in point along the continuum of student learning. The PSAT/NMSQT and SAT have been revised as well, with the latter as the anchor of the suite. The Suite of Assessments prioritizes the tracking of student progress over time, so that both teachers and students can identify areas of improvement and work on them. Content changes The redesigned SAT will no longer require essay writing, as it did very recently; instead it will offer the essay as an optional component some colleges may ask of their applicants. The four tests will have a Reading Test, a Writing and Language Test, and a Math Test, all of which are closely aligned. An important change to note is theres greater emphasis on words in context, instead of obscure or archaic vocabulary for which the SAT has been famously known. Other key content changes focus on student command of evidence, analyzing a source, essential areas of math, real-world contexts, analysis in science and social studies, and close readings of U.S. founding documents and engagement in global conversation. Be sure to use an updatedprep bookwhile reviewing for the exam. [RELATED:How is the New SAT Scored?] Revised scoring system Instead of losing a quarter point for each incorrect answer, students will no longer be penalized for guessing. In addition, all four tests will use a common score scale so that growth in certain skills can be easily tracked across assessments. As an added bonus, this scale will include more scores (subscores and cross-test scores), so students will have better information about how they are performing on the test. Lastly, in this new system, the SAT will revert back to a 1600 point scale from 2400. [RELATED: What is an Average SAT Score?] Knowing what to expect with the updated SAT Suite of Assessments is the first step toward comprehensive preparation. Watch out as the new and redesigned tests roll out in September 2015 (PSAT 8/9), October 2015 (PSAT/NMSQT), February 2016 (PSAT 10), and March 2016 (SAT). While most colleges are planning on accepting scores from old and new versions of the SAT, if youre in the current college application cycle, you may want to check with the specific college, as well as any updates from The College Board itself.

How Much Time Should I Spend Practicing Guitar

How Much Time Should I Spend Practicing Guitar Suzy S. When youre beginning to learn guitar, you also have to learn how to practice. Follow this expert advice from guitar teacher Mike B. to find the proper amount of practice time you need to achieve your guitar goals   As a guitar instructor, one of the most common questions I get asked is how often should I practice? Students are told various amounts of time that are deemed proper to practice each day. Some say a half hour, some say an hour, some say more, some say less. With all of these conflicting guitar practice tips how can you make the proper decision regarding the amount of time you spend with your instrument each day? As an instructor, and as a person who practices every day, I feel it all comes down to the individual. Since every person has different interests, different levels of ability, and different goals, it would make sense for everyone to have a different practice schedule. In my opinion, the amount of time one spends practicing should be dictated primarily by your current goals. Your current goals can be defined as the material you need to get through before the next lesson, or any material you want to master outside of your guitar lessons. When you are just starting out and have only been assigned a few chords or melodies to work through it may not make sense to spend an hour a day practicing. It may make more sense to spend fifteen or twenty minutes a day practicing since there isnt much material available to work through. On the other side of the coin, a much more advanced student that has a lot of material to get through should spend more time practicing. The more material you have available to play should equal more time practicing. In an ideal world you should spend however much time is necessary to get through your material each day. In the real world that simply is not always possible, for a few reasons. First, people have schedules, commitments, social lives, and other responsibilities to occupy their day, so they simply can not spend the majority of each day practicing. Second, if you practiced the same exact material every day you would most likely get pretty sick of it. What is important in this situation is to set aside an amount of time that you can commit to each day, and prioritize what needs to be worked on each day. Time When it comes to time spent on the instrument, consistency is key. If you can devote an hour a day Monday through Friday to practice thats great. If you can only devote a half hour a day that works too. Whatever you can come up with will work, as long as you are consistent. Practicing five hours one day and then not touching the guitar for a week will not do you anywhere near as much good as simply playing every day. Material Once you have decided how much time you can realistically devote to the instrument each day, I find it very helpful to list out the material you are seeking to master. For example, say an intermediate student is currently working on chords, scales, arpeggios, a few songs, technique, and reading music. This student has decided to devote forty-five minutes every day to practicing. Within a forty-five minute span of time every one of these subjects could be touched upon. However, it might make more sense for the student to divide these subjects over the span of two days, rather than just one, and alternate his or her practice schedules. When doing this, prioritize what needs the most work, what needs to least amount of work, and assign each subject an amount of time. Some material may need to be touched upon on both days. Some material may be touched upon on both days but in different forms(Major and minor chords for example). For example: Day One     Minor Chords 15 minutes Song 1 10 minutes Scales 5 minutes Technique 10 minutes Reading music 5 minutes Day Two Major Chords 5 minutes Reading music 10 minutes Song 2 5 minutes Song 3 10 minutes Arpeggios 15 minutes By breaking up the material over two days you can spend more time on each subject, and keep your practice schedule fresh and interesting. I dont feel there is a magic answer when it comes to the question how much time should I spend practicing? The right guitar practice tips depend on the student and their goals. Focused and consistent practice will yield the best results. Quality of time spent can be a lot more important that quantity of time spent.

Making the Tutorfair TV Ad

Making the Tutorfair TV Ad We filmed our very first TV advert at Bishop Challoner Catholic Collegiate School (BCCCS) on Commercial Road, back in November 2015. Our ad will air in January, watch it below! BCCCS is a Tutorfair Foundation partner school, The head teacher Nick Soar, kindly lent us an Art room, a Maths room, and their Library for filming. We also had some of BCCCS’s best drama students and teachers take part on the day, who are the stars of our TV ad! Scene 1: The “Primary Class” In my opinion this is the best scene in the Tutorfair TV ad, maybe because it was the most elaborate scene we filmed, the first scene we filmed and the opening scene in the ad! Before 9am the Year 7 students had already been to hair and make-up (with Bella the make-up artist), taken their seats and practiced the scene a few times before filming! The girls and boys were all giggling and chatting away; the energy in the room was fantastic! Isabella, the star of this scene, plays a student who has missed something in class. After a few more trial runs, Mike the director calls out “Film rolling? OK, action!” Bringing home the reality that we were on a REAL film set! Very. Exciting. The class teacher asks the class “How does Tommo feel about Charlie and Molly?” This question I later discovered, referred to the book called “Private Peaceful” that the students were reading for English Literature. Isabella’s classmates all raise their hands to answer, whilst Isabella shows off her top acting skills and plays a student who feels a little left behind. It’s surprisingly difficult to act without speaking, without overacting or under-acting, with all the lights shinning on you, a fluffy microphone boom above your head, and no less than 9 “grown-ups” standing behind the camera staring at you! So we were all more than impressed with Isabella’s composure, relaxed attitude and expert drama skills, as she didn’t need much direction at all! #nailedit Isabella is in fact one of BCCCS’s top year 7 students; she reads one book every week, loves story writing and problem solving, aims to take her GCSEs early, and in her spare time she is a pro-baton twirler! When asked if she was enjoying the day, she exclaimed “Yes! I am really loving all the attention!” as she really was the leading lady! Personally, my wow moment was when I saw the camera platform, which was attached to a track on the floor. When “action” was called, it was slowly pushed to the right by the camera assistant, which gives the scene a slow and steady panning effect across the classroom. Simple things… But I was dying to have a go! In the final edit of the television ad, this scene is only a few seconds long, but it took roughly 2.5 hours to set up and film, with the class practicing and repeating the scene roughly 10 to 12 times! So by the end of the filming I was desperate to find out for myself how “Tommo was feeling about Charlie and Molly”! Scenes at Home Before the filming day we visited BCCCS and chose some rooms to film in. One of the rooms chosen was the staff meeting room. As we saw the room during half term, it was being repainted and was largely empty. We chose this room to film all the “home tuition” scenes in. Once we'd finished filming the first scene, we walked over to the staff meeting room to set up the next scenes. When we opened the door and we were faced with a huge (brand new) boardroom style table that filled the room and was screwed into the floor... There was no moving that table, we had to think of another option! Thinking on our feet, we had an idea, and went to the Library! We hadn’t arranged to be in the library until after lunch, so the students studying that morning were kindly keeping quiet, but we heard giggles as they watched what could only be described as a very budget episode of “changing rooms” as we TRANSFORMED a corner of the Library into a “home”. We used vases, flowers, a tree, a sofa (I still don’t know where that came from!), a rug bought from the local market, and even hung some fabric as if they were curtains! Laurence Llewelyn-Bowen would have been proud… In the Library “home” we filmed: - The private tutoring scene with Isabella and Mark Maclaine. - The scene with Isabella and her “mum” choosing a tutor, who was played by Rachel from the education company, Spiral. - The scene with the older teen boy, and Madeleine (one of Tutorfair’s top tutors) We then rearranged the Library to look more like a Library again, and filmed student Victoria, with Peter Kirby the director of the Tutorfair Foundation. This appears as the final scene in our TV ad! By this time (due to the time spent making a house in the library), we had run over schedule and it was home-time for most students - Yet we still had one more scene to film in the Maths room. We only had 4 GCSE students to make a full classroom scene, so we needed to find more extras to take part. I was then asked to put on a blue shirt, along with my college Sebastian, and sit in the back of the classroom as a student! Being over 10 years older than my classroom peers, I felt quite flattered to play the role! We were asked to calculate the area of a circle…  â€œAha! Of course! A = pr ²   I knew that… This scene only took around 5 takes and that was a wrap! It all came to an end so quickly, but I had such a truly incredible experience, as did the students and teachers of BCCCS. We would like to thank Nick Soar, James who coordinated EVERYTHING, and the Dancing Aardvarks. Special thanks to the teachers and students who brought the ad to life!
