SIXTH GRADE

Today, we practiced rounding decimal numbers. Remember, to round a decimal number, first find the place that you are supposed to round to. Then look at the number to the right. That number tells the first number what to do. If the number on the right is 5 or greater, then the first number goes up one. If the number on the right is 4 or less, the first number stays the same. Drop all numbers after the number you rounded to. Here are a few examples:

Example 1: Round to the nearest thousandth:

0.00587

The 5 is in the thousandth place. If you look to the right, you see an 8. An 8 would make the 5 go up one - so the 5 changes to a 6. Then drop the numbers after the 6. Your answer would be:

0.006

And that's it!

Here's another one:

Example 2: Round to the nearest hundredth:

25.02378

The 2 is in the hundredth place. If you look to the right, you see a 3. A 3 would make the 2 stay the same. Then, drop all the numbers after the 3. Your answer would be:

25.02

Here's one more that's more complicated:

Example 3: Round to the nearest hundredth:

5.9975

The second 9 is in the hundredth place. If you look to the right, you see a 7. A 7 would make the 9 go up one. But going up one would make it a ten. You can't put a ten in one decimal place, so you put a 0 and carry a 1 to the next place to the left. But that's a 9 too, so now it goes up to a ten. Put a 0 there as well and carry another 1 to the next place to the left...that would be where the 5 is now. So the 5 ends up going up 1 to a 6. It would look like this:

5.00 ------ this is the same as just a plain 5, so you could just write 5.

Now, after you have rounded all the numbers on the page, go back to each of the numbers I circled and write the number that was printed on the page (not your answer) and write that number in words. So, for Example 1 above, I would write:

Five hundred eighty-seven ten-thousandths

Example 3 would be written as:

five and nine thousand nine hundred seventy-five ten-thousandths

Be sure to write if you have any questions!

SEVENTH GRADE

Math: We talked about how to subtract integers today. It is a little complicated, so we just spent time going over it for the class period. There is no homework!

Geography: We continued painting our globes. They are looking terrific! They may not be "perfect" but everyone is really getting a good sense of where the continents are on the Earth. It's a very good spatial activity.

EIGHTH GRADE

Pre-Algebra: Is It Scientific Notation? worksheet. Remember to first change all of the numbers in improper scientific notation to correct scientific notation. Then take those numbers and write them in standard form.

Algebra I: Order of Operations. Do the evens on both sides of the worksheet. Then, write 3 "stories" using an animal and a food that demonstrates order of operations. You must use 3 operations on at least one story. On the others you must use at least 2. Here is an example:

Rocky hid 7 acorns under the pine tree. Then he stacked 2 piles of 6 acorns each behind the large rock. How many acorns did he hide? This would be: 7 + (2 x 6) = 19! Be creative! We will share our best story tomorrow.

Have a great evening!
