Sixth Grade

Literature - Questions over Chapter 7 of The Golden Goblet.

Spelling - Unit 12 is due tomorrow! Please be sure you have completed the unit and studied the words.

Math - Lesson 38. To add and subtract decimal numbers and whole numbers, you still write the numbers lining up the decimal points. Remember, to write a whole number with a decimal point, you put the decimal point to the RIGHT of the whole number. So, 12, becomes 12.

Then line up the decimals and add or subtract!

For the problems about squares, if you are given the perimeter, you can find the length of one side by dividing by 4. (A square has four sides that are all the same.) So, if a square has a perimeter of 20 inches, then each side is 5 inches long. (4 sides at 5 inches long each means a perimeter of 20 inches.)

Now, suppose you wanted to find the area of square when you are given the perimeter. If the perimeter is 24 inches, first divide by 4 to find out how long each side is. For this square, each side would be 6 inches long. To find the area of a square, remember that you multiply side times side - or in this case, 6 inches x 6 inches. So the area is 36 square inches.

Vocabulary - Unit 5 and the cards are due tomorrow! Please be sure you have finished the unit.

Literature - Treasure Island Chapter 2 questions.

Grammar - pg. 68, exercise B and DWS. For DWS, remember that you are underlining the adverb used ONCE and the word the adverb describes TWICE. For exercise B, just follow instructions.

Math - Lesson 33. Comparing and Rounding Decimals. Remember, when you order decimals from least to greatest, you can do two different things, but for either method, you first need to write the decimals up and down as if you were adding (lining up the decimal points). For the first method, start with the largest place and compare all the numbers in that place. If they are the same, move on to the next place and compare those. Keep going until you have your order. Here is an example:


The other method is to fill in empty places with zeros and compare the numbers after the decimal point. Here is an example of that:

Pre-Algebra. Lesson 38. Coordinate Plane. This new concept for this lesson is a review over graphing points on a coordinate plane. Everyone did an excellent job remembering how in class today.

Algebra I - Ratio problems. To do the problems that aren't word problems, you simply cross multiply and solve the resulting equation.

For word ratio problems, I will do an example:

See you tomorrow!
