Comparing and Ordering Fractions

Two Helpful Rules for Comparing Fractions

Hello,
I mention these in the accompanying video, but I wanted to have them in print as well. So here goes:

LIKE NUMERATORS
To have like numerators means that two or more fractions have the same numerator (top number). When comparing fractions with like numbers, follow these steps:
1) Make sure the numerators are the same.
2) Look at the denominators (bottom numbers)
3) The fraction with the larger denominator is the SMALLER fraction. Again, the fraction with the larger denominator is the SMALLER fraction.

Example:
2/5 and 2/9
They both have 2 in the numerator. So I look at the denominators. 9 is the larger denominator, so 2/9 is the SMALLER fraction. Therefore, 2/5 is greater than 2/9.

LIKE DENOMINATORS
To have like denominators means that two or more fractions have the same denominator (bottom number). When comparing fractions with like denominators use these steps:
1) Make sure the denominators are the same.
2) Look at the numerators
3) The fraction with the smaller numerator is the SMALLER fraction.

Example:
3/8 and 5/8
They both have 8 in the denominator. So I look at the numerators. 3 is the smaller numerator, so 3/8 is the smaller fraction. Therefore, 3/8 is less than 5/8.

Math Race Hall of Fame

In order to encourage the students to challenge themselves a bit more with regard to Math Races, I have instituted the Math Race Hall of Fame. Each day I will nominate two problems, one from a boy and one from a girl, in each class. At the end of the week, the students will vote for what they think is the most impressive problem. The winners will then be photographed and their photo, which will show their problem, will be placed on display in the hallway. Their photo will stay on display for one week until the next weekly winner is announced. With 4E's play going on, they have not yet done Math Races, so 4C already has 4 nominees while 4E has none. Please encourage your child to design challenging Math Race problems. Be sure that they pay attention to the order of operations as they create their problems.

4C Math Race Hall of Fame



Here are the nominees for Friday, February 18th.

Help with Multi-Step Word Problems

Hello all,
One skill that we have been focusing a lot of attention on this quarter has been the ability to solve word problems with multiple steps. These multiple steps usually require using different operations as well. I am currently working on a list of websites that could provide some at home practice. I have placed one such link below. Check it out and let me know what you think. Have a good day.

Math Playground

The nice thing about this site is that it provides a video explanation of the solution.

Just thought I would share a quick video of my daughter Leland showing off her dance "skills".

4C Math Races

The video is cut short, but it did capture the majority of the math race explanations for the day. I have challenged the 4E students to do more difficult and interesting problems tomorrow so that their math races may be posted. Enjoy!

Happy Almost February

Hello all,
I hope that everyone had the chance to enjoy the wonderful weather this past weekend. I know my family and I did. As you can see from several of my previous posts, I am utilizing video quite a bit in my classroom. Not only is it a great way to communicate what is going on in our classroom, but it is also a wonderful way to provide opportunities for remediation when students need it. I have focused mainly on math, but will be including science activities in the coming weeks. I am also planning on having a video blog post with updates about the class. The students will actually help to create these video blogs so be sure to check them out. Have a great day!

Mr. C

Data Analysis

Hello all,
Over the next few days I am planning on showcasing some videos from our class. I will be focusing specifically on Math Races. I would like you all to see just what it involves and how it is a great tool for learning. The video below is only of the data analysis portion of today's math races with my homeroom students. Unfortunately,there were some technical difficulties and I wasn't able to tape the checking portion. Have a great day.

Snow Day

Hello everyone,
I am pretty sure most of you won't check this, but as it is my New Year's resolution, I thought I would post something. I was thinking about an idea to continue our discussion of pH. It would be great if the kids could collect some snow and let it melt and then bring it to school on Tuesday, or the next day we come to school. I would love to test the pH. My prediction is that they would be somewhat similar, but you never know. Today would also be a great day, between the sledding, snowball fights, and hot chocolate, to do some snow related science experiments. I am sure there are experiments that your kids could set up using snow and other readily available items. I hope everyone enjoys the snow. Take care and see you soon.

Mr. C

P.S. Here are just a few ideas that I found on the web. Happy Snow Day!

How clean is snow? Collect a few cups of snow. Put it in a saucepan and heat it to melt. Cover a bowl or jar with a layer of paper towels or porous cloth, held in place with tape or a rubber band. When the water is cool enough to pour safely, pour it slowly through the paper towel layers or white cloth. Examine the paper or cloth to see if any specks of dirt or sediment were in the snow. Find any? Still think snow is clean enough to eat?

Make ice castles. Gather up some plastic bowls, cups, small tubs or basins, and plastic drink glasses, etc. Take these outside and fill them with water. (The temperature must drop below the freezing point of 32 degrees. ) Overnight, the containers will freeze and the next day you can warm the containers and tump the ice forms out. Make these into castles as you would play with sand on the beach. With water you can "glue" the shapes together. Adorn the tops with small icicles.

Colored snow lights. Kids in Germany make these lights in the winter. You will need to fill three containers with water. Add food coloring to the water containers to make blue, green, and red water. Now make up a batch of snowballs, about ten for each color. Dip each in a colored water. Mound the colored snowballs in little mounds like igloos with one side left open. Place a small candle in the center of each snowball mound. Light will glow out through the colored snowballs and make lights along your sidewalk or garden path.

Snow Blindness Goggles. Snow reflects so much light that explorers and travelers in snowy regions many times found themselves blinded by the brightness. Make a pair of snow glasses by cutting a section of cardboard about six inches long and about three inches tall. Hold the cardboard up to your face and ask someone to help you by marking where your eyes are with tape or stickers. Cut narrow slits to see through across the tape marks and a "V" shape to fit over your nose. Punch a hole in each end and tie a long rubber band section to each hole. Tie the bands together to fit your head. Try going outside without the glasses and then putting them on. Can you see better with them? Do you still have to squint?

How strong is ice? For this experiment you will need a plastic jug like milk or juice comes in. It must have a screw on lid. Fill the jug to the top with water and screw the cap on firmly. Now set the jug outside. The water will expand as it freezes and burst the side of the milk jug

pH Activity - January 7, 2011

Welcome Back!!!

It has been a great first week back from our holiday break. The kids did a wonderful job getting back to work. We were able to cover a lot of ground. Here are some of the highlights of the week:

MATH
We spent the week reviewing how to do lattice multiplication. This method is just another tool that the students may use to solve more difficult multiplication problems. I created a video tutorial to explain the process and how it connects to partial products. This week also brought the start of our basketball math season. Building on the skills learned during football math, the students will again use real life statistics to simulate basketball games. Each student will play one game against each of the other students in the class. We will then have our own version of March Madness. It should be a lot of fun. All the students should continue to work on their basic facts. I have seen excellent progress, but there is still some room for improvement.

SCIENCE
This week we had some interesting discussions about the causes and effects of acid rain. We will continue our discussion of pollution next week when we talk about farm and salt run-off. I think the favorite part of the week for most of the kids was the pH activity we did today. The students brought in a variety of household substances so that we could test the pH in each of them. Lots of truly investigable questions were generated from this activity. Here are some examples:
* What would happen to the pH if you mixed some of the substances?
* How do you measure the pH of thick substances (i.e. jello, chocolate syrup)
* Would different flavors of soda have different pH levels?
Be sure to check out a few of the pictures from today's activity.

Have a wonderful weekend!!!!!!
