Integer temperatures

Today we used our cold, cold Winter as inspiration for our lesson on integers.  Here's what we accomplished:

We also assessed Winter and Summer temperatures across the lower 48 to determine the best location to live...  The winner was Florida!!!

I hope that you enjoyed these activities!  I had fun!  Thanks to Virginia, NO HOMEWORK!

Integers

Today we started working with integers!  Read below if you are confused or need a reminder.  More tomorrow!!!

Homework is to complete the worksheet (looks like ^) for homework if you didn't complete it in class.  It should be very quick!  Good luck!  See you tomorrow!!!

Quiz Tomorrow!

Please complete the review worksheet tonight to prepare for the quiz tomorrow!

From Purple Math:

Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the "equals" sign in (5)(5)(5) = 5³. The "exponent", being 3 in this example, stands for however many times the value is being multiplied. The thing that's being multiplied, being5 in this example, is called the "base".

This process of using exponents is called "raising to a power", where the exponent is the "power". The expression "5³" is pronounced as "five, raised to the third power" or "five to the third". There are two specially-named powers: "to the second power" is generally pronounced as "squared", and "to the third power" is generally pronounced as "cubed". So "5³" is commonly pronounced as "five cubed".

When we deal with numbers, we usually just simplify; we'd rather deal with "27" than with "3³". But with variables, we need the exponents, because we'd rather deal with "x⁶" than with "xxxxxx".

From Math is Fun:

Exponents

The exponent of a number says how many times to use the number in a multiplication.

In 8² the "2" says to use 8 twice in a multiplication,
so 8² = 8 × 8 = 64

In words: 8² could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"

Exponents are also called Powers or Indices.

Some more examples:

Example: 5³ = 5 × 5 × 5 = 125

• In words: 5³ could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"

Example: 2⁴ = 2 × 2 × 2 × 2 = 16

• In words: 2⁴ could be called "2 to the fourth power" or "2 to the power 4" or simply "2 to the 4th"

Exponents make it easier to write and use many multiplications

Example: 9⁶ is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9

You can multiply any number by itself as many times as you want using exponents.

Tonight's homework is worksheet 2-4.  Feel free to use a calculator!

Some more review!

More review again today!!!  You should really know what you're doing by now!  If not, you have "targeted" studying for homework.  Focus on the topics you had difficulty with as you study tonight!  Some of you asked for another copy of the study guide.  You can find printable images of the assignment below the answers to today's work in this blog post.
