February 26: Review for Unit 6 Test

We are taking the Unit 6 Test tomorrow, so today we spent the class period reviewing the topics that will be covered.  We did not take any notes but instead went through several problems on the homework packet.


FUN FACTS FOR FRIDAY:

One of the most interesting Number Patterns is  Pascal's Triangle  To build the triangle, start with "1" at the top,  then continue placing numbers below it in a triangular pattern.  Each number is the two numbers above it added together  (except for the edges, which are all "1").

(Here I have highlighted that 1+3 = 4)

Patterns Within the Triangle

Diagonals The first diagonal is, of course, just "1"s, and the next diagonal has the Counting Numbers (1,2,3, etc). The third diagonal has the triangular numbers. (The fourth diagonal, not highlighted, has the tetrahedral numbers.)

Fibonacci Sequence Try this: make a pattern by going up and then along, then add up the values (as illustrated) ... you will get the Fibonacci Sequence.  (The Fibonacci Sequence starts "0, 1" and then continues by adding the two previous numbers, for example 3+5=8, then 5+8=13, etc)
