Customary Conversions

We started converting in the customary system using proportions today and also converted some random conversions too!  Keys on a piano...  Cards in a deck...  Miles in a marathon...

The assignment will be corrected on Monday.  If you want it to be eligible for the 100's box, every problem must be completed.  Now it's not homework, BUT if you didn't finish, you might want to try to finish this weekend so you can hopefully get your paper in the 100's box!

Finding Conversion Factors

So BYOD *kinda* worked today. Please finish both sides of the conversions worksheet tonight if you didn't finish in class. Remember, use the internet, almanacs, printed resources, etc to finish it. If you really get stuck on one, please skip it. Don't spend more than about 15-20 minutes on this assignment!

Remember the golf balls have more than one answer, sorry, I thought it was a standard amount from my research. Yards in a bolt should be the largest average amount you find.

Conversion sheets with reminders:

Thanks for your hard work despite technology glitches! We'll use this information in class tomorrow for our activity!

Converting between Fractions and Decimals

Today we went over converting between Fractions and Decimals.  Please find notes and examples from class below.

(warm up question)

Fractions to Decimals

Decimals to Fractions

Examples from tonight's homework

If you have any questions about tonight's homework, please flip it over and take a look at the notes on the opposite side for help.  You can also watch the videos below!

Some fraction, place value, decimals, etc reminders:

Have a great night!

Day two of CMT Prep!

Tonight's homework is to complete strands 3 and 6.  They should go pretty well, but here are some pointers for strand three from MathIsFun:

Fractions, Decimals and Percents

Converting Decimals to Fractions

Converting Fractions to Decimals

Converting Decimals to Percents

Converting Fractions to Percents

Equivalent Fractions

Converting between Mixed Numbers and Improper Fractions

Good luck on tonight's HW!  Feel free to work on strands 10, 11, 12, 15 and/or 21 if you finish tonight's hw and have some time to do more work!

Converting in the Customary System!

Now, I told you how foolish I think that the Customary System is during class today, but let me prove my point a bit...


These are the countries that use the Customary System:
* USA
* Liberia
* Myanmar (Burma)

These are the countries that use the Metric System:
EVERYONE ELSE!!!!!!!

Metric System in Green, Customary in Pink

We reviewed the various units of measurement for the Customary System and some of the conversion factors...

Specifically for each type of measurement, we copied down conversions as listed below:

Since the volume/capacity seems to be the most confusing, I have included two different ways to help you remember the conversions, The Big G and Gallon Boy!

We used proportions to help us solve conversions within the customary system.

Step one:  Write the conversion factor as a fraction

Step two:  Set up the proportion with corresponding labels

Step three:  Enter the information that you already know

Step four:  Use basic math facts or a calculator to determine what goes in the blank to solve

Proportions and Customary Units Review

Tonight's homework is to complete the worksheet I passed out in class on, "Converting in the Customary World" both sides.

More Fractions and Decimals

Today's Objective:  After reviewing the concept by correcting last night's homework, students will practice expressing fractions as decimals and decimals as fractions.

We corrected last night's homework and I was pleased that so many people did so well!  Quite a few papers ended up in the 100's box!  We spent some class time working on another practice sheet,  It isn't homework, and most of you finished it in class, but if it comes in completed on Monday, it is eligible for the 100's box!  If you can spend five minutes checking it over, we can have quite a few papers added again on Monday!!!  The worksheet has 11 problems on it!

I also handed out some notes and an extra practice paper if you want to do a bit more.  Again, you don't have to complete these, they are just to help you!  See images from that sheet below!

Homework is to have a nice weekend!

Converting between Fractions and Decimals

Today's Objective:  After learning how to convert, students will be able to express fractions as decimals and decimals as fractions.

Today we used three techniques to help us convert between fractions and decimals.  One was easy, one was hard(ish) and the other was in between.

First, we realized that both fractions and decimals represent parts of a whole.

The first thing we did was the medium difficulty technique of changing a fraction into a decimal.  We tried to make some simple fractions into equivalent fractions over either 10 or 100 so that we could easily convert them to decimals.

Next, we started working on the more complicated technique of dividing the fractions.  To do this, we divided the numerator by the denominator, adding a decimal and annexing zeros to solve the problem.

We found that the answers sometimes stopped as a simple decimal (terminating) while others just kept on going (repeating).

The last, and easiest technique we used for converting was for making decimals into fractions.

We see it, say it (properly), write it (as a fraction), and simplify it!

Practice:  

Tonight's homework is to complete both sides of the converting worksheet.  I did a few problems with you in class, also shown below, so the work shouldn't take too long!

Thanks!  Best of luck on tonight's homework!

Customary Conversions!

Today we began working with actual conversions in the Customary System!

What you need to know:

LENGTH:
1 foot = 12 inches
1 yard = 3 feet = 36 inches
1 mile = 1,760 yards = 5280 feet

MASS:
1 pound = 16 ounces
1 ton = 2000 pounds

LIQUID CAPACITY:
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces

  

Want some more reminders?  Check out this previous blog post.

As you know, today we used proportions to help us solve our homework problems.  Remember to set up the first fraction with what we already know using the labels from the problem...

ex:  4 ft = ______ in

12 inches
  1 foot

Then complete the set up by using what we want to know as part of the second fraction.

12 inches  --   ? inches
  1 foot     --     4 feet

Then use multiplication (or sometimes division) to help you solve the proportion

                x4

12 inches  --   ? inches
  1 foot     --     4 feet
               x4




                x4

12 inches  --  48 inches
  1 foot     --     4 feet
               x4





I hope that this helps!  We will get more practice in class tomorrow!!!!


Tonight's homework is both sides of the customary conversion worksheet.
