"It's no secret that fractions are a very difficult concept for students to understand. But why is that? Fractions are an extremely abstract concept, and without adequate concrete and representational experiences, students do not develop mental images of what the abstract symbols mean.   In Texas, students begin formal fraction instruction in 2nd grade under our newly adopted TEKS, but the symbolic notation for fractions (1/4, 2/3, etc.) is not taught until 3rd grade. The 2nd grade standards include: partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part use concrete models to count fractional parts beyond one whole using words and recognize how many parts it takes to equal one whole Let's take a closer look at each."

"'ve been reading a powerful new resource titled Beyond Pizzas & Pies, by Julie McNamara and Meghan M. Shaughnessy.  They describe fraction sense this way: Fraction sense implies a deep and flexible understanding of fractions that is not dependent on any one context or type of problem.  Fraction sense is tied to common sense: Students with fraction sense can reason about fractions and don't apply rules and procedures blindly; nor do they give nonsensical answers to problems involving fractions."

Several great links in this blog post for teaching fractions.

A tutorial that models fractions with circles and number lines.

"Virtual and Augmented Reality apps are starting to hit the market in force. While most of the buzz for these technologies has been for immersive gaming, many companies are getting involved in realizing the potential that Augmented and Virtual Reality may have as educational tools. The fraction of projected VR and AR market value taken up by education may seem small, but considering how large whole market is, this "small fraction" still represents Billions of Dollars. This article will discuss 22 virtual and augmented reality apps for education that are already available, in beta, or still in the testing process. Some of the apps are aimed at parents and preschool teachers, while most are for primary school teachers. Others will interest anybody, including higher education students, and even non-students."

"The following example is a piece of work about simplifying algebraic fractions that illustrates the value of student explanations. The task was to make a video explaining how to simplify the three fractions below, complete with full explanations. No training was given on how to do this, and no apps were recommended. This was my first attempt at asking this particular group of students to create a video. It follows that after years of simply writing down answers and them either being right or wrong, several students decided to assume that I was joking with this task and simply handed me in a copy of the answers. Job done. Or was it Wolfram Alpha's job done? Anyway, here is what a few responses to the task looked like"

"PBL (Problem Based Learning) has long been an important aspect of my teaching programme. This term in my Year 6 Mathematics Class we have been learning about Fractions and Decimals. After doing some learning about how to use and manipulate them effectively and developing an understanding of chance, the students have been set a problem based around filling a gap in the market.   The students were set a problem based on filling a gap in the market. The problem was: "The educational board game market is severely lacking fraction, decimal and chance based games to support learning"."

"It could be very soon that every child amputee can don a bionic arm in their favorite Disney character's colors for a fraction of the current price. This result will be thanks to Open Bionics and 3D printing. This week, a clinical trial of 3D printed bionic hands for children starts in Bristol. The trial is the world's first and could result in children receiving bionic hands at a fraction of the regular cost of £60,000. Funding from the Small Business Research Initiatives scheme made the trial a reality. 3D printing plays a large part in the price decrease from £60,000 to a projected £5,000. This is thanks to the technology's ability to offer amputees a custom fit at the same time as speeding production. If the trial is successful, bionic hands for kids could soon be available on the NHS (the national healthcare system for the UK). The hands would also feature kids' favorite Disney characters."

"A few years ago I blogged about the concept of Video Tagging and how I was using it to improve performance in my PE Classes. Back then the process was much more involved and required a tremendous level of setup and expensive dedicated hardware and software. This ultimately led to minimal take up within the PE community regardless of the massive benefits to learning. Flash forward to 2013 and we are now in a position easily tag video with a couple of mobile apps, which have a combined price of $8.48. Not only is this price a mere fraction of the cost involved in the 2011 example, it is without a doubt a much more accesible option for the masses. Check them out below;"

"Back in February, an EdWeek Market brief reported that Amazon Education was starting to beta-test a new platform with educators, helping teachers navigate the jungles of open educational resources (or OERs, for short). Well, that platform-Amazon Inspire-has officially launched today in tandem with the ISTE conference in Denver, Colorado. A free, mostly-OER platform (see below for why it's "mostly OER"), Amazon Inspire works like a search engine for educational videos, lesson plans and games. Users can search by criteria like topics (say, "fractions" or "the Constitution"), standards, grade level, and time to complete, as shown below; additionally, they can rate materials with 1 to 5 stars."

"At GeekDad we are big fans of apps that actually use mobile devices in innovative ways to support children's learning. Motion Math Games are one of those developers who have led the way in thinking about how they can design digital learning environments that provide ways for children to learn math with their hands and minds. Their first fraction/decimals app called Motion Math has become one of the benchmarks against which others should be comparing themselves."

" In this episode we featured 11 free mathematics game-like apps that focused on currency/money and fractions for both elementary and secondary. For each app we shared a brief description and then multiple ways the app could be used in the classroom (e.g. stations, assessment, remediation)."

"Do you cringe when a student's reaction to every problem involving fractions is "cross multiply!"? It doesn't matter whether you teach elementary or high school, whether you're a parent or a tutor, having a student yell out a trick without stopping to think is painful. This book is filled with alternatives to the shortcuts so prevalent in mathematics education and explains exactly why the tricks are so bad for understanding math."
