Such a simple game but yet so effective at improving Adding and Subtracting! Warning: Addictive!

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 who created the game. Adding and subtracting Games | ICT | Interactive White Board | Lesson starters.

Homer Simpson's scary maths problems

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.

You can have other tessellations of regular shapes if you use more than one type of shape. You can even tessellate pentagons, but they won't be regular ones. Maths1.

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.

Squaring two digit numbers in your head

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. Turns out I'm not so weird after all (well, apart from the finding doing mental arithmetic fun bit). I've been reading Secrets of Mental Math: The Mathemagician's Guide to Lightning Calculation and Amazing Mental Math Tricks and the author, Michael Shermer, is just like me: he works from left-to-right. He, like me, has found this to be a good system because it lets you discard digits early and not hold some enormous calculation in your head.

The books is filled with tricks for doing all sorts of mental calculations, including a nice section about estimation (I've always been an estimator) and working out things like tips and sales taxes. Mathematical mysteries: Hailstone sequences. January 1997 This problem is easy to describe but it is one of mathematics' unsolved problems.

Mathematical mysteries: Hailstone sequences

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. If n is odd, multiply it by 3 and add 1 to give n' = 3n + 1. Then take n' as the new starting number and repeat the process. N = 5 gives the sequence. 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. Here's how it worked. 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.

Binary numeral system. The binary or base-two numeral system is a representation for numbers that uses a radix of two. It was first described by Gottfried Leibniz, and is used by most modern computers because of its ease of implementation using digital electronics--early 20th century computers were based the on/off and true/false principles of Boolean algebra. Binary can be considered the most basic practical numeral system (the Unary system is simpler, but impractical for most computation). Modeling integers.

When modeling integers, we can use colored chips to represent integers. $1,000,000 Problems. MathPickle and The Pacific Institute for the Mathematical Sciences (PIMS) are exploring options for establishing thirteen unsolved problems - one for each grade K-12. The thirteen problems will mirror the $1,000,000 millenium problems, but whereas the millenium problems are intended to inspire mathematicians, the thirteen $1,000,000 unsolved problems are intended to inspire K-12 students and teachers. The reward money is to be split between the person who solves a problem and their most inspirational K-12 teacher.
