Sixth Grade

Lesson 53. Remember the rule for dividing fractions: Change the division sign to multiplication and flip the second fraction.

Seventh Grade

Grammar - We finished grading the punctuation packet and discussed the grammar test on Friday. The students took notes over what topics will be on the test. Be sure you are going over all the rules for commas, quotations, and apostrophes!

Math - Converting Metric Measure - Worksheet A

To do these, remember to use your notes to find the correct multiplier. Here is an example:

The first step is to write 3.75 cm over 1. Since you don't convert straight from cm to km, use a multiplier that will change cm to m and the another one to change m to km. Then, you choose the correct way to write the multiplier. Since 1m = 100 cm, write it with 1 m on top and 100 cm on bottom. You will always know which one to put on bottom by looking at what you are starting with. Since you are starting with cm, you need to cancel the cm out, so the 100 cm needs to be on the bottom. Next, choose the correct way to write the conversion for m to km. Since we want to cancel out the m and be left with just km, you need to put 1,000 m on bottom and 1 km on top. Then, cross off the measurements that cancel. Since the 100 and 1,000 are on the bottom, you are dividing 3.75 by 100 and then by 1,000. To do this, just move the decimal to the LEFT 5 places. (5 zeroes in 100 and 1,000 so 5 places)

Here is another example:

First, write the 0.75 m over 1. Then, determine the multipliers you need. m to cm and then cm to mm. Write the m to cm with 100 cm on top and 1 m on bottom so you can cross off the meters. Then, write the cm to mm with 10 mm on top and 1 cm on bottom so you can cross off the cm. You are left with only mm as your measure. This time, you will be multiplying by 100 and 10. Since 100 and 10 have 3 zeroes combined, you will move the decimal to the RIGHT 3 places.
