Sixth Grade
Today was a short class due to the House meeting in the afternoon, so we spent our time grading the papers from Thursday and practicing a different way to multiply large numbers. There is no homework!
Seventh Grade
Math - Math class was short today due to the House meeting, so we spent the time going over Thursday's test. While most everyone did fairly well, some students got confused and make several mistakes. Because of this, I'm allowing anyone who wants to, to retake the test on Monday and I'll average the two grades together. The retake will be basically the same except the numbers will be different. Here are the explanations for the test:
1. The 3 is in the hundred trillions place.
2. The 2 is in the billions place.
3. The 9 is in the hundred millions place.
3 (second one - I numbered wrong!). The 7 is in the hundred thousands place.
4. To write the number in words, it would look like this: three hundred forty-five trillion, twelve billion, nine hundred eighty-six million, seven hundred five thousand, one hundred five.
5. The 3 is in the millions place.
6. The 6 is in the ten thousands place.
7. The 9 is in the trillions place.
8. To write the number in words, it would look like this: five hundred seventy-nine trillion, one hundred eighty-two billion, one hundred forty-three million, seven hundred sixty thousand, five hundred seventy-one.
9. This property is the Associative Property of Addition. Notice that the order of the numbers doesn't change, but what is in parentheses does. This shows you that it doesn't matter which two numbers you add together first, you still get the same answer.
10. This is the Commutative Property of Multiplication. Remember that commutative property shows you that it doesn't matter what the order is, the answer is still the same.
11. This is the Identity Property of Multiplication. Remember that "identity" means the number doesn't change....so whenever you multiply a number by 1, the number stays itself.
12. This is the Zero Property. Here, you see that anytime you multiply a number by zero, the answer is always zero.
13. This is Commutative Property of Addition. Again, commutative means that the order doesn't change the answer. You are flipping the order that you add, but it's still the same.
14. This is the Distributive Property. Remember that "distribute" means to "pass something out" and here, the 2 is getting passed out to the 5 and the 7.
15. This is the Identity Property of Addition. Remember again, "identity" means the number stays itself, so Identity of Addition is showing you that every time you add zero to a number, the number doesn't change.
16. This is Associative Property of Multiplication. Here, the order of the numbers doesn't change, but what is in parentheses does. This shows you that multiplying numbers in a different order, doesn't change the answer.
17. The additive identity is zero because you can add zero to any number and it doesn't change.
18. The multiplicative identity is one because you can multiply one by any number and it doesn't change.
19. Identity means that the number stays itself.
20. Here, just choose a property that makes a lot of sense to you and explain it!
Geography - The class took a test today over Chapter 2. No homework!
Eighth Grade
Both classes took tests today. There is no homework!
See you tomorrow,
