Warning: Addictive! Thanks to flashmaths.co.uk for this addictive game to improve “adding” and “subtracting”.

I have used it many times for low ability sets as starters and plenaries and it really gets learners engaged. The lower sets tend to be small so it is a great way to end the lesson by getting everyone to have a go. Be warned groups can get very excited when playing this, so you will need to manage the behaviour well. Throughout the year I keep track of the scores and we work out everyone’s averages, range and the highest score wins a prize. Give it a go and let me know what you think in the comments section below, but all credit goes to flashmaths.co.uk who created the game.

Homer Simpson's scary maths problems. For a character living in two dimensions, grasping the idea of life in 3D can be tough - especially if the character in question is Homer Simpson.

But one Halloween episode of The Simpsons forces him to confront the concept, and gives viewers a mathematical workout too. Eighteen years ago, the writers of The Simpsons celebrated Halloween with one of their traditional Treehouse of Horror episodes, which included three short stories. After Attack of the 50-Foot Eyesores and Nightmare on Evergreen Terrace, viewers were treated to Homer³, which contains the most intense five minutes of mathematics ever to appear on prime time television. For many people, mathematics is more terrifying than being attacked by an army of zombies, werewolves and vampires, but in this case the various equations were included because the writer of Homer³, David S Cohen, is a fan of numbers.

Squaring two digit numbers in your head. All my life I've done mental arithmetic the 'wrong way': I've calculated from left-to-right, instead of right-to-left.

So when I do something like 24 + 35 I'll see the 50 first and then the 9 . This even applies when there's a carry and I'll do something like 36 + 56 as 80 + 12 . I do the same thing for multiplication as well. Mathematical mysteries: Hailstone sequences. January 1997 This problem is easy to describe but it is one of mathematics' unsolved problems.

Starting with any positive integer n, form a sequence in the following way: If n is even, divide it by 2 to give n' = n/2. Addition Trick. I must have been in about fourth or fifth grade.

I was visiting my grandparents, when my uncle got out a pen and paper, saying he had a math trick to show me. He explained that by magic he could predict in advance what the result of an addition sum would be. Now, I know it wasn't magic at all, but by the end of the trick, it certainly seemed magical. 10 Easy Arithmetic Tricks. Technology Math can be terrifying for many people.

Edit Article CalculatorUsing Prime FactorizationFinding Square Roots Manually Edited by NatK, Maluniu, Luís Miguel Armendáriz, Webster and 44 others In the days before calculators, students and professors alike had to calculate square roots by hand. Several different methods have evolved for tackling this daunting process, some giving a rough approximation, others giving an exact value.

To learn how to find a number's square root using only simple operations, see Step 1 below to get started. Dance, Factors, Dance – A Variation On Yorgey's Factorization Diagrams. Upon first sight of Brent Yorgey’s brilliant Factorization Diagrams, I knew that I should take his lovely little dots and make them dance. Our first tango would be inspired by the digital clock, with a separate diagram for each of the hours, minutes, and seconds. For example, we’d portray 4:34:27 am like so: One night, plans discreetly set, we stole away, rendezvoused, and had our fun prancing about. But alas, although our encounter had grace, it begged for drama. Quite simply, there wasn’t enough panache – dynamic range – because while hours go up to 23, and minutes and seconds to 59 (*), the diagrams don’t really start cooking until they reach the triple digits.
