Pattern Links

Isn't it fascinating that a pattern can be represented as a graph, a table and an equation?!?

We'll be doing more link sheets tonight for homework and all through next week.

Please also complete the worksheet handed out in class.

Fibinocci

One of the most famous patterns in the world was designed by the Italian mathematician, Leonardo di Pisa -- better known as Fibinocci.

His sequence goes like this: seed it with 0, 1 and then add the two numbers to get the next.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 ...

Get it?

Magic Square

We practiced them in class, and now it's your turn to build one.

Yours should follow these rules:
  • Be a 3x3 or 4x4 square
  • Include positive and negative numbers
  • Have one row that gives away the solution

Don't remember what a magic square is? Check it out here.

Subtracting Integers

Subtracting integers can be really easy ... especially if you follow this rule:

Write the problem as a sum by changing the second integer to its opposite.

Ex. -6 - (-2) = -6 + 2 = -4

or

-6 - 2 = -6 + -2 = -8

Remember a double negative creates a positive.

Try the worksheet tonight and we'll review tomorrow in class.

Adding Integers

Here's the most basic of rules:

The sum of 2 positive numbers = positive

5 + 2 = 7

The sum of 2 negative numbers = negative

-7 + -1 = -8

But you do need to watch the values of the numbers when adding a positive and a negative number.

4 + -1 = 3

4 + -8 = -4

Please complete the worksheet tonight for homework.

Integers and Absolute Value

Integers are negative and positive numbers.

Absolute value tell us the distance a number is away from zero.

So both -3 and 3 have an absolute value of '3' since they are each 3 places away from zero on a number line.

This weekend, please finish questions 11-53 on pg. 19 & 20 of your book.

Variables and Variable Expression
