Once again do not forget what we have covered so far. We now know how to convert between fractions, decimals and percents. We also know how to order them on a number line.
On Tuesday we talked more about IRRATIONAL numbers. These are numbers that can not be represented as a ratio of 2 integers. Do you remember what kind of numbers can be represented as a ratio of 2 integers?
You then learned about PERFECT SQUARES and SQUARE ROOTS. Perfect squares are rational numbers who's square root is a whole number. An example is 25. The square root of 25 is 5.
There are rational numbers who have a square root that is irrational or a rational number but not a whole number. An example is the square root of 45. We can estimate this square root to be between 6 and 7, but closer to 7.
To square a number you multiply the number by itself. Squaring a number involves using an EXPONENT. The exponent we use when we square a number is 2.
The last thing we talked about was STANDARD and SCIENTIFIC NOTATION. Standard notation is just the number written out with all it's digits. Scientific notation is a number between 1 and 10 multiplied by a power of 10.
Remember that at any point I should be able to quiz you on your perfect squares and you should know them. We will also continue to take multiplication blitz's until everyone can master them.
We will be taking a test this week that will cover everything we have talked about so far. Be sure to look over the Week in Reviews to make sure you will do great on the test. You all are doing a great job so far. Keep up the great work.
Remember to be successful you must:
DO WORK
STAY FOCUSED
