WEEK OF SEPTEMBER 7-11, 2015
DEAR MIGHTY FALCONS,
I FEEL MORE FAMILIAR WITH YOU KIDS NOW AND I LOVE HOW WELL YOU WORK INDEPENDENTLY AND I ALSO NOTICED YOU ARE VERY MATURE WHEN WORKING IN GROUPS TOO! YOU GUYS ARE AWESOME PROBLEM SOLVERS AND MATHEMATICIANS KEEP UP THE GREAT WORK!
THIS WEEK WE WILL BEGIN CLASSIFYING RATIONAL NUMBERS, IDENTIFYING OPPOSITES AND ABSOLUTE VALUE OF RATIONAL NUMBERS, AND COMPARING AND ORDERING RATIONAL NUMBERS. REMEMBER WE ARE A TEAM AND ARE HERE TO LEARN TOGETHER.
NOTE: WE WILL BE HAVING A SHORT 3RD WEEK ASSESSMENT THIS WEEK SO MAKE SURE YOU CONTINUE TO GO OVER YOUR MATH INTERACTIVE NOTEBOOKS. ALSO, MAKE SURE YOUR PARENTS SIGN THE WEEKLY LOG EVERY THURSDAY AND GO OVER THE WORK WITH THEM FOR EXTRA PRACTICE. REMEMBER TO "TEACH" THEM WHAT YOU HAVE LEARNED IN MATH CLASS AND ASK THEM QUESTIONS ABOUT THE LESSON JUST LIKE I DO IN CLASS :) THIS WILL HELP YOU GET BETTER IN CLASS!
Rational Numbers
A Rational Number is a real number that can be written as a simple fraction (i.e. as a ratio).
Here are some more examples:
| Number | As a Fraction | Rational? |
|---|---|---|
| 5 | 5/1 | Yes |
| 1.75 | 7/4 | Yes |
| .001 | 1/1000 | Yes |
| -0.1 | -1/10 | Yes |
| 0.111... | 1/9 | Yes |
| √2 (square root of 2) | ? | NO ! |
Oops! The square root of 2 cannot be written as a simple fraction! And there are many more such numbers, and because they are not rational they are called Irrational.
Another famous irrational number is Pi (π):
