Multi Digit Multiplication Strategies - Mr Elementary Math. Look at the problem below and think about how your students would respond to the two questions: What is the value of the 2?

Why should we place a 0 in this space? If your students answer the questions by saying, “the 2 is worth 2,” or “I placed the 0 in that area because I was always told to move it down,” consider the idea that the student(s) do not fully understand the concept of multiplying multi digit numbers. The life and numbers of Fibonacci. Fibonacci is one of the most famous names in mathematics.

This would come as a surprise to Leonardo Pisano, the mathematician we now know by that name. And he might have been equally surprised that he has been immortalised in the famous sequence – 0, 1, 1, 2, 3, 5, 8, 13, ... – rather than for what is considered his far greater mathematical achievement – helping to popularise our modern number system in the Latin-speaking world. Fibonacci Sequence. The Fibonacci Sequence is the series of numbers: The next number is found by adding up the two numbers before it.

The 2 is found by adding the two numbers before it (1+1) The 3 is found by adding the two numbers before it (1+2), And the 5 is (2+3), and so on! Example: the next number in the sequence above is 21+34 = 55 It is that simple! Count On. Fibonacci Puzzles The Fibonacci Numbers are a sequence of numbers that start with 0 and 1.

The rest of the series is determined by a simple rule: Add the latest two numbers to get the next one. Here are some puzzles where the answer is "The Fibonacci Numbers"! So, now you know the solution (!) Easier Fibonacci Number puzzles. All these puzzles except one (which??)

Have the Fibonacci numbers as their answers. So now you have the puzzle and the answer - so what's left? Just the explanation of why the Fibonacci numbers are the answer - that's the real puzzle!! Puzzles on this page have fairly straight-forward and simple explanations as to why their solution involves the Fibonacci numbers;. Puzzles on the next page are harder to explain but they still have the Fibonacci Numbers as their solutions.
