Further Ken Robinson Creativity

This is another outstanding TED talk where Ken Robinson explains how we can improve education in the world. Ken highlights some key points about how education is failing learners and how we can change this. This video is a must watch as it leaves you inspired and motivated to change your practice.

“Children are not suffering from psychology disorders, they are suffering from childhood”

Sir Ken Robinson outlines 3 principles crucial for the human mind to flourish — and how current education culture works against them. In a funny, stirring talk he tells us how to get out of the educational “death valley” we now face, and how to nurture our youngest generations with a climate of possibility.”

Take a look at some of the Ken Robinson books that are available and worth a read if you are in need of some inspiration. You can also take a look at Ken Robinson’s TED video on changing education paradigms for another thought provoking talk.

Ken Robinson – How to escape education’s death valley

So you want to know how to cheat on your Mathletics Maths homework and avoid a possible Maths detention! This is an interesting eye opener for teachers and Learners about online Maths homework set on Mathletics. This hack gets all the answers for your maths homework and lets you get extra points and marks. Take a look at the 3 methods below, the third is the most recent method updated.

I do have several pieces of advice that I have summarised below but beware that it might not be what you had hoped, but take a look anyway. So you have been searching the web for the ability to hack the system to get all the answers to your maths Mathletics task.

Independently try and teach yourself the maths behind the task and you easily get full marks and get that all aspiring “free stuff”. In the long term it is in your best interest to learn the material and apply the knowledge as the hack below will not be able to help you in a Maths exam or later on in life. It is also very likely that the Mathletics team have already read this post and fixed the bug. I know because I have already submitted the links to them!!

The video is self explanatory but unfortunately pupils I have sent the bug to Mathletics to deal with, so by the time you read this it might have been fixed and you will not be able to easily do your maths homework. Why not ask your Maths teacher for help or get yourself a Maths tutor.

The second method can be found on the next page.

If you are looking for dirty Math jokes then this is not the place, these are the the best funny Maths Jokes ever and are guaranteed to make you smile and laugh! The Math jokes below are a collection based on number of retweets on twitter and likes on face book. I think the jokes show that us Mathematicians can be funny if we want to be. ). If you still do not believe we can be funny then check out this funny Math calculator that is certain to make any Math class laugh.

Do not worry English teachers you can check out the Top 10 Funny English Puns. if you are feeling a little left out.

If you have any funny Math jokes that you want to added to the list then tweet @magicalmaths and we will try and get it added. Alternatively, remember that comments are FREE, so let us know what you think below.

Before you take a look at the Top 10 funny maths jokes watch the video below which explains some funny maths jokes.

Top 10 Funny Math Jokes

1) A Roman walks into a bar, holds up two fingers, and says: ”Five beers, please.”

2) Why is 2 x 10 the same as 2 x 11? Because 2 x 10 = 20 and 2 x 11 equals twenty two

3) Two men walk into a bar. One orders H20, the other says I’ll have H20 too. The second man dies.

4) An infinite number of mathematicians walk into a bar, the 1st orders a beer, the 2nd order 1/2 a beer, the 3rd orders 1/4 a beer. The bartender gets frustrated and says “You are all idiots and pours 2 beers”

5) Why are powers like fish? Because they’re all indices!

7) Why was the maths teacher late for school? Because he got on the rhombus! (@lauren_lsm)

I am regularly asked about advice on the best Maths revisions guides or books to buy. The answer really depends on the type of student and type of Maths course they are studying. It is very important that pupil revision is active, which means the student should be doing Maths rather then just reading over a topic. To revise a topic effectively learners should be applying a skill by answering questions. Many of the Maths Revision books below have some very good problems solving activities and well defined questions with scaffolding in the correct places.

This is an amazing video showing a new fluid simulation technique, using Position Based Dynamics approach. The water looks so real, so it is hard to believe that this is just a digital simulation of water.

This would make a great starter to a ICT lesson on animation or a science lesson on water.

We are 2 musical teachers who have developed a free Primary and SEN maths music resource ( ). Songs are centred around an alien called Adam Up who uses a magic calculator to solve various mathematical problems. Bearded ‘Number Crunchers’ pop out of the calculator and sing tricks and concepts using memorable, thematic, simple and catchy songs. We are still in the editing process but have lots of songs available in video/audio form. To be honest, we are looking for global domination and therefore trying to build up as many users/followers as we can before the final product comes out.

When I was in the classroom, I used to tell students that if two students had exactly the same answers to a GCSE paper, some right, some wrong, then the one who showed their working out would get the better marks.

I used to ban correction fluid, not because they would sniff it, but because the working out and mistakes were important to me as a teacher trying to help them understand some aspect of mathematics.

So I have always been wary of online offerings that rely on multiple choice, on simple correct/incorrect analyses and on inputting the correct answer only. Offerings that completely miss the working out, the different ways students reach an answer, the reasoning as to WHY they reached an answer.

Providing good learning analytics is hard work. So generally, we only do easy learning analytics. “Student x took 10 minutes and scored 65% on subject test y”. “Student y moved to level 3 after 10 questions”

“Getting learning analytics wrong on the learning dimension is a recipe for disaster, (it) must be done carefully and with understanding. Without a semantic ability to understand what is happening, we won’t even know if we’re doing harm to our students by using algorithms to optimise for things we don’t understand”.

But how can we do things differently and what should, could, we do to get this understanding?

And to avoid doing harm to our students?

Michael Feldstein in his ‘Taxonomy of Adaptive Analytics Strategies’ draws on the work of Kurt Vanlehn’s best practices in learning design of describing outer loop and inner loop learning.

  • Outer loop learning is that indicated above. Did the learner get the correct answer?
  • Inner loop learning examines the steps a learner is taking to solve a problem and at appropriate moments, intervenes to provide feedback directly relevant to some mistake the learner is making.

So to create an online offering where inner loop learning takes place, and in which all that learning is fed back to the teacher… that sounds good to me.

Students get hints when they need help, and be able to progress. They have to show their working out, and indicate their reasoning when solving a problem.

Teachers will be able to see all that feedback and all the working out for every student in the class.

They will be able to analyse by student – where did a student need help, even if the question was eventually right. Or analyse by question – which questions did more of the class have a problem with? What part of what question did they have a problem with?

All with the aim of aiding teachers to help students, and to help students understand more.

Now as noted above, this has not been possible in the past, but a company in Australia, Mathspace, is about to launch in the UK. In our opinion, it does Inner Loop learning and provides help to the students and details to the teacher, in real time, that have never before been possible.
