Pi (π) has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated π to that number of places, we would still only be approximating its actual value. Here’s a brief history of finding π.
The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation.
The Rhind Papyrus (ca.1650 BC) gives us insight into the mathematics of ancient Egypt. The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π.
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
We are reposting a tweet below about participating in a research project about #Dyscalculia research opportunity with #Microsoft on how dyscalculia and other #learningdisabilities impact students’ ability to be successful in math. The interview will take place between October 1-5, 2018. For more info email: firstname.lastname@example.org:
A petition has been filed in the Supreme Court by a student of Indian Institute of Technology (IIT), Mumbai with a learning disability, challenging a Bombay High Court judgment that rejected her claim to a Master of Design degree.
The petitioner Naman Varma, who has a learning disability called ‘Dyscalculia’, has filed this petition through Advocate Anand Varma. The petition claims that the approach of IIT Mumbai was not in line with the provisions of the Persons with Disabilities (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995.
Many charter schools do enroll special education students, some even actively seek out special needs students, and they are paid a premium to do so — $26,197.24 for a special-education student versus $8,327.35 for a regular-education student. However, some charters have been known to only enroll students with less severe disabilities and require less services, than students whose disabilities are more severe or are costly to accommodate.
However lately practices surface where special education children are being refused based on their disability apparenlty. Investigations are ongoing
Enjoy 50% of our video series for parents who want to help their children with math homework. Dr Schreuder demonstrates her favorite ways of teaching and about 150 pages of downloadable sheets with activities, templates and games are included.
Thanksgiving is coming. A good time to work a bit with your children on math while also keeping it light and entertaining. There is a pinterest board with lots of resources that are all about Math, not necessarily Dyscalculia, and fun to do.
Watching the first part of Stupidhead!, the lovable, sincere and silly musical comedy about dyslexia, one is suspicious that its writer-performer is even dyslexic. For one thing, she can spell d-y-s-l-e-x-i-a, something that even Einstein could easily not do. She has trouble with math, organizational skills and directions home – same here – so maybe she’s not so much dyslexic as she is harebrained.
Turns out, Katherine Cullen suffers from dyscalculia, a numbers-based dyslexia that is a legitimate (if niche) learning disability and, as one can imagine, an utterly frustrating condition. Which is what Cullen’s two-hander Stupidhead! is all about: Frustration – frustration with one’s brain, and the audacious overcoming of shame and limitations.
New, or altered, legislation has been introduced in the state of West Virginia.
It calls for all students in Kindergarten to be screened for dyslexia and dyscalculia. Also children in grade 1 through 6 ( I guess if they missed the screening earlier) Next when they find something they need to provide a real assessment and effective intervention. Also money is made available to provide Professional Development for teachers on the topics. Great news!
GCSE maths exams are deliberately designed to fail a third of all young people, according to the education charity National Numeracy.
The charity wants to see a new benchmark – a numeracy equivalent of the driving test – which sets out the essentials of practical maths that teenagers will need for adult life and the workplace. Unlike GCSE, this would be something that all young people would be expected to achieve as part of their maths education and that could be embedded within the existing curriculum and exam pathway.
Interesting story today. We have all heard about the computerized training modules that aim to train your brain to do things faster or better. Although the vendors usually report amazing results, science continues to be sceptical. In our link for today however a story from the Netherlands where one of their major league soccer teams trains their juniors with computer games for the match on the field!
Well one Dutch professor thinks so and points at a study where pupils got 6 weeks of arithmetic drilling and that put them 18 months ahead. The question is for how long that advantage stayed and if those pupils had been rightfully diagnosed with dyscalculia
The 2016 New Europe 100 is the third annual list of central and eastern Europe’s brightest and best people — plus the organizations who are changing the region’s societies, politics or business environments and displaying innovation, entrepreneurialism and fresh approaches to prevailing problems.
Maciej Rys is the Founder of EarlyLogic, a cloud-based educational technology which digitalises diagnosis and therapy of dyscalculia and other mathematical disorders in children between 3 and 9 years of age and she is honored by inclusion in this very exclusive list.
The Museum of Mathematics could use some help. They need pictures featuring math for their seeing Math initiative. Check out the information in our link for today, grab your camera and look around for Math in the real world.
Over a decade ago, Texas officials arbitrarily decided what percentage of students should get special education services — 8.5 percent — and since then they have forced school districts to comply by strictly auditing those serving too many kids, a Houston Chronicle investigation has found.
Their efforts, which started in 2004 but have never been publicly announced or explained, have saved the Texas Education Agency billions of dollars but denied vital supports to children with autism, attention deficit hyperactivity disorder, dyslexia, epilepsy, mental illnesses, speech impediments, traumatic brain injuries, even blindness and deafness.
OK they do not mention Dyscalculia but the path is clear.
The Welsh government is serious about math and has realized that parents can not always help their children with homework. So they pulled together some resources to help that including online videos with explanations.
The US Department of Justice just released final regulations regarding the implementation of the American for Disabilities Act. “These rules clarify and refine issues that have arisen over the past 20 years and contain new and updated requirements.”
The regulations should be shared with ALL schools and workplaces when requesting accommodations.
See the appeal for help from all of us, by Steve Chinn, who will work on getting a leaflet together about problems people might experience around their dyscalculia in their workplace or in applying for jobs.
