The origin of the Fibonacci Sequence

The Fibonacci sequence is a series of numbers where a number is found by adding the two previous numbers in the series.  Starting with 0 and 1, the sequence is … Term X0 X1 X2 X3 X4 X5 X6 X7 X8 X9 Value 0 1 1 2 3 5 8 13 21 34 The 2 is found by adding the two numbers before it ( 1+ 1) The 3 is also found by adding the two numbers before it (2 + 1) The 5 is found by adding the two numbers before it (3 + 2)  etc … If we…

How kids with dyscalculia may struggle socially

Dyscalculia makes life difficult.  Having dyscalculia usually makes math class a humiliating experience, it also makes some common everyday skills difficult as well. Knowing left from right, reading a clock, using standard instruments of measurement such as a ruler or measuring cup, courting money and making change are a few examples.   But perhaps the most painful problem dyscalculia gives us is the social challenges it creates.   We can always find a way to avoid numbers, in fact we spend most of our time NOT working with numbers. Math class only lasts about an hour a day.  But we are always social. We can never avoid being social no…

Dyscalculia… why its important we learn more about it

Here’s a simple question for you to answer, which number is larger 55 or 23? The answer is of course 55, most of us can answer this question in less than 0.5 seconds.  But there are a few who will take as long as 3 seconds.  These people may have something called dyscalculia.  Dyscalculia (also known as number blindness) is a condition in which a person’s number sense is defective.  People diagnosed with dyscalculia usually have problems correlating they symbol for a number (for example 7) with the number of objects the symbol represents.  Counting is also difficult for them.  This of course…

Why estimating should be an important part of every math class

“How long does it take you to drive to work” is a very common question asked, have you ever noticed that the answers we get to this question is almost always a range and never a precise single number?  As in “About 15 – 20 minutes” as opposed to “18 minutes”. When it comes to answering questions dealing with quantity (like how long it takes to drive to work) we seem to be incapable of giving a precise single number as answer.  When asked how “How many people showed up to the Christmas party?” we answer “about 100, 150”.  When…

The Man Who Hated Math

Former British Prime Minister Willian Gladstone hated math.  He hated math so much that when he was in university he wrote a letter to his father asking to be transferred to a University that did not offer any classes in math.  As a member of Parliament Gladstone’s father could have easily arranged for a transfer to a “no math” university for his son, but instead he replied “You say that you dislike math, but there is a supreme pleasure to be found in putting all your efforts into a subject that you dislike.  You may be faced with a time…

Subway Map that makes Studying for Advanced Functions Easier!

Studying for an exam in mathematics is not fun for many students.  The biggest complaint I get about studying for a math exam is the amount of concepts that have to be reviewed in order to prepare. I always feel disappointed when I hear students tell me how much anxiety preparing for a math exam is causing them.  As a mathematics teacher I always hope students can see how the concepts we work on over the semester connect with each other (wishful thinking on my part I know!) .  Ideally by the time exams come around they understand the concepts so well (because they see the connection between…
