SIXTH GRADE MATH

Today's lesson was over estimation and rounding. The assignment is on pages 10-11,  #11-32. When you are supposed to round, you can round to numbers that are easy to use. The book doesn't specify the place to round to, so you might find it easiest to round to the largest place, but you also might round to the nearest 10. Because rounding is an estimate, there are several reasonable answers. I will be looking for those. You might have a different answer than your classmate, but you could both still have reasonable answers. Here is an example:

322 + 78 + 12 = 300 + 80 + 10 = 390 (rounded to the largest place)

322 + 78 + 12 = 320 + 80 + 10 = 410 (rounded 322 to the nearest 10)

Both would be acceptable. The second answer is closer, but the first is still okay.

For compatible numbers, remember you are trying to find numbers that multiply or divide easily. You won't necessarily round to the closest 10 or 100. For example:

59 divided by 7 could be changed to 56 divided by 7 to get 8. It is better to change just one number, if possible, in order to get the closest estimate.

Here is another example:

107 divided by 11 could be changed to 110 divided by 11 to get 10. You might also round 107 to 100 and 11 to 10 and you would still get 10. Either is acceptable.

SEVENTH GRADE MATH

Most everyone finished in class. If you still have a few left and are confused since you don't have the tiles, ask tomorrow and I can help you with the tiles.

SEVENTH GRADE GEOGRAPHY

Today we talked about the different kind of world map projections. Then I passed out the Atlases. The class began working and an Atlas Activity worksheet to become familiar with the atlas. This is due tomorrow.

PRE-ALGEBRA

Everyone finished the homework in class and then I showed them how to play an integer addition/subtraction dice game.

ALGEBRA I

All three finished the assignment in class.

See you tomorrow!
