Sixth Grade
Lesson 92 - Expanded notation with exponents. To do these, you are going to do the same thing as regular expanded notation replacing the powers of 10 (10,000, 100, 100,000) with the number 10 and an exponent. How you know what exponent to use is to count the number of numbers after the digit. For example, in the number 56,000, you would write (5 x 10 to the 4th power), by writing the 4 as an exponent to the 10. You know it's 4 because there are 4 digits after the 5. Then, you would also write + (6 x 10 to the 3rd power) with the 3 as an exponent to the 10 since there are 3 digits after the 6. (I can't do exponents with regular typing on the blog!
Also, don't forget that when you raise a fraction to a power (a fraction to an exponent), you are multiplying the fraction by itself however many times indicated by the exponent.
Seventh Grade
Literature - There is a quiz over Chapters 10-15 of Tom Sawyer tomorrow. Be sure you are studying the vocabulary.
Grammar - pages 177-181. Exercises A & B. Follow instructions. Remember, it is a misplaced modifier if there is a phrase that is out of place and describes something it shouldn't describe.
Spelling - This week's unit is #32. Be sure you are working on it and studying each night!
Math - Lesson 7-9. Percent decreases. Remember, you first find the amount of change by subtracting the two numbers. Then, write it over the original number, which will be the first number listed. Make this equal to p over 100. Here is an example:
For the problems on the second page, you will be writing the cost on the bottom of the first fraction. You do not know the loss, which in these problems is the same as the change. Make it equal to your percent over 100. Here is an example:
Your assignment is #2-18.
