Math - Lesson 43. Simplifying, comparing, and ordering decimal numbers. Remember, anytime you have a decimal number that has zeros at the end, you can drop off those final zeros. For example:
0.0300 is the same as 0.03 or simply .03
To compare two decimal numbers, you can do two things. One is add zeros at the end to make the decimal places the same and compare the numbers after the decimal point. For example:
Compare: 0.092 0.92
You can add a zero after the 0.92 to make is 0.920 (It's the exact same number.)
Now, you can compare the numbers after the decimal. In 0.092, you see the number 92. In 0.920, you see the number 920. Since 920 is bigger than 92, then 0.92 is bigger than 0.092.
The other method is to write the numbers vertically as if you were going to add. Line up the decimal places like this:
0.092
0.92
Now look at the places as columns. In the ones place, both numbers have a zero. So you move on to the next place to the right - the tenths place. The top number has a zero in the tenths place and the bottom number has a 9 in the tenths place. That means that 0.92 is bigger since 9 is bigger than 0.
You can use either method above for ordering numbers too.
Literature - The students are giving their book reports so there is no homework!
Seventh Grade
Spelling - Unit 14 is due tomorrow. Be sure you are finished and don't forget to STUDY!
Literature - We read some from Treasure Island today. No homework.
Grammar - pp. 71-72. Exercises A, B, and DWS. Follow instructions on exercise A. For exercise B, you only need to write the compound preposition. You do not have to rewrite the sentence. For DWS, follow instructions.
Math - Investigation 4. #5-12.
To make a stem and leaf plot, you first have to decide what the interval on the stem will be. Since all of the numbers are two digits, the stem should probably be 10's. The leaves are the numbers to the right of the line. Each of those numbers, along with the stem number, stand for one of the numbers in the list. So, if there's a 2 on the stem and a 4 as a leaf, that number is 24.
To find the range, subtract the highest number from the lowest number.
To find the mode, look for the number that occurs MOST often.
To find the median, locate the middle number. You can do this by counting how many numbers there are. If there is an odd number, divide your number of numbers by 2 and round up. So, if you had 27 numbers, 27 divided by 2 is 13 1/2, so your median is the 14th number. If you have an even number of numbers, find the middle TWO numbers and average them. (add them and divide by 2)
You find the quartiles in the same way, only you are using one half of the numbers. For the first quartile, find the middle number of all the numbers LESS than the median. To find the third quartile, find the middle number of all the numbers GREATER than the median.
To make the box and whisker plot, use the example in the book as a guide to setting up your plot.
