## Monday, November 26, 2007

This will be your second growing post. You will have to have it done the week before Xmas Break.

Title this growing post @@@@@'s 2nd Growing post
Label it growingpost,@@@@@yourdisplayname,roomnumber

Question 1 Use this picture and reflect on your the puppy kibble test.

1. What strategies were needed?
2. How did you use these strategies?
3. Or How could you of used these strategies.
4. How would you figure out the price of a 6 cup bag of Betty's Snack mix? Use a ratio table
5. Find 3 other values (amounts of Snack Mix) that could be solved using the same ratio table. Find the \$\$ of your new container sizes.
Question 2
You are going to create a voicethread explaining the strategies you used on your test. You need to choose 4 out of the 6 questions.
1. 2/3 + 1/4 + 2/5 =
2. 6/5 - 11/10=
3. 3/5 + 2/7 =
4. 1/6/+1/9 =
5. 5/6 - 1/4 =
6. 3 3/5 - 1 4/5 =

I recommend the following. Choose your 4 questions. On plain pieces of white paper redo them like you did on your test. Make sure your drawings are large enough. Take a picture of them and save them to your desktop. Upload these images to voicethread and embed your voicethread into your blog.

At voicethread you need to describe what you did to solve the problems. How did you use clocks, money etc to solve the questions. You need a minimum of 2 comments on each picture.
Here is a video explaining how to make a voicethead and embed it into your post. You should have both of these questions done by the end of the weekend.

Wednesday December 5
3.) Here is your 3rd growing post question.

Today in class we reviewed the 6 strategies from the RACE Investigation. They were
• Equivalence
• Fractions show operations
• Ratio Tables (Proportional Reasoning)
• Measurement
• Partial Products or the Distributive Property
• The Whole Matters
• Friendly Fractions
Create a voicethread or write and use pictures to describe how you would uses those strategies to explain how far the two students would have run if Mark ran 7/8 and Rachel ran 11/12 of the RACE course.

4. Your last question deals with pizza. You need to explain which group gets the largest portion of pizza. All student groups get the same sized pizzas. It is up to you to cut them up so that they are shared equally.

1. Group 1 Sally Bob, Gidget and Biff Share 3 pizzas.
2. Group 2 Stan, Holly, Barry, Ben and Ichkabibble share 4 pizzas.
3. Group 3 Eric, Susy,James, Betty, Veronica and Moose share 5 pizzas.
4. Group 4 Paul, Alex, Chris, Jughead, Archie, Reggie, Mr. Wotherspoon and Midge share 7 pizzas.
• How much pizza does each student get in the different groups?
• Which group gets the largest portion of pizza?

Your Growing Post is due on December 17th at 9 AM. Thank you for working hard in advance.

You will be responsible for a self-evaluation and peer evaluations next week.

Welcome to your first Growing Post.

A Growing Post is 1 post. You will edit it over and over again making additions to it. This post is worth marks. You will be expected to show your knowledge of fractions and learn how to blog at the same time. Have fun and do not leave things to the last minute.

1. Create a post and call it ****'s First Growing Post.
2. Label it growingpost, fractions (write it exactly like that please)
3. In the body of your post please answer the following question. You need to use words and a picture. Which set of fractions is larger 1/2 + 1/6 or 1/4 + 7/12. I would recommend that you use the idea of clocks to show your understanding.
4. Find your picture of your final project "The Bike Race Fundraiser" at flickr
5. Once you are at flickr and find your picture save it to your desktop or where ever you save your pictures. You should label it ***bikerace. Then upload it to the blog. Once it is there you will have to select it (double click) then cut it and put it into the right spot at in your post. Tell us 2 things about your bike race.
Thus ends part one of the growing post. Stay tuned for part 2!! (This work is due by Monday)
(update Friday Oct. 19)
Here are some more things to do
6. Do a google search for fraction games. Find a good site and write a review of the game. Tell everyone what is good about this site. You also need to create a link to the site.
7. Go back to your picture of the bike race. Tell us all about how you calculated the Km positions at a twelfth, sixth and a third. did you see any patterns?
8. What are 2 different ways to find a quarter and 3/4 of a number. Use one of the following 16, 22, or 110.

Happy weekend

Tuesday October 23
9) Write a fraction question and answer it. It has to be a question like one you have had on a test. You may answer it in pictorial or word form.
10) Mark your own Growing post and one other persons growing post. Use the following guide. Paste it in as a comment. Be honest. You may mark a persons work from another room. You may not mark a person's post that has already had a person mark it. Look before you comment.

### A time for Scribes

Mr. Kuropatwa introduced me to the world of Scribe Posts. It is an essential part of the Grade 8 Math Classroom. You will be expected to write one scribe post every 30 classes or about 4 a year. That doesn't sound like to much does it.

A Scribe post is

The assignment is simply to post a brief summary of what happened in class each day. A different student is responsible for the daily scribe post and they end their post by choosing the next scribe. The first scribe is a volunteer. The teacher's daily involvement is limited to updating a post called The Scribe List which is at the top of the links list in the sidebar of the class's blog.

To complete a scribe post the student must

Write a brief summary of what we learned in class today. Include enough detail so that someone who was away sick, or missed class for any other reason, can catch up on what they missed. Over the course of the semester, the scribe posts will grow into the textbook for the course; written by students for students. Remember that as each of you write your scribe posts. Ask yourself: "Is this good enough for our textbook? Would a graphic or other example(s) help illustrate what we learned?" And remember, you have a global audience, impress them.

Here are examples of good scribe posts Pythagoras Scribe One Day In Math Algebra Masterpiece

Here are some scribe posts that have made The Scribe Post Hall of Fame.

When you are done your scribe post choose another student to be the scribe and label your post scribepost.

### Choose a question

What patterns do you see in this string. Describe how you see in this string. Can you find 3 or more?

Todays test asked 1/2 +1/3 does not equal 2/5. What evidence did you use to convince me?

## Monday, October 01, 2007

### How do you share 17 subs between 22 people?

• fractions show division
• the size of the whole matters
• friendly and unfriendly fractions
Thanks
Harbeck

## Wednesday, September 26, 2007

Here are 3 examples of what we talked about in class today. Please leave a comment behind telling me what you like about the example (1, 2 or 3) and how does it explain the questions or ideas we were talking about in class.

The questions or ideas were,
1. Fractions are relations, the size or amount of the whole matters.
2. Fractions represent division with a quotient of less than 1.
3. With unit fractions the greater the denominator the smaller the fraction.

Have a good night

Harbeck

### Some Fraction Thinking?!!

1. Fractions are relations-- the size or amount of the whole matters.

2. Fractions may represent division with a quotient less than 1.

3. With unit fractions , the greater the denominator the smaller the piece is.

### Some Fosnot Homework

Today in class we had an excellent Math Congress. All of you agreed that 10/12 was larger than 7/10. How can you prove this to me using words, numbers and pictures?

We also discussed fractions as division.

In this number string what patterns do you see happening?

How can we use the patterns you recognize in this picture to help us determine whether 10/12 is larger than 5/6?

Welcome to your 3 questions that need to be answered. Once again they are...

1. Today in class we had an excellent Math Congress. All of you agreed that 10/12 was larger than 7/10. How can you prove this to me using words, numbers and pictures?

2. In this number string what patterns do you see happening?

### A couple of How to videos

How to get a Google Account

How to join up to the class blog.

What you need to do at your Google Account or AKA all the Google goodies that are waiting for you!!

### Think before you Blog

A Colleague of mine Mr. Kuropatwa created this post for his students. Since it is Internet Safety Week please pay attention to the videos below.

Blogging is a very public activity. Anything that gets posted on the internet stays there. Forever. Deleting a post simply removes it from the blog it was posted to. Copies of the post may exist scattered all over the internet. I have come across posts from my students on blogs as far away as Sweden! That is why we are being so careful to respect your privacy and using first names only. We do not use pictures of ourselves. If you really want a graphic image associated with your posting use an avatar -- a picture of something that represents you but IS NOT of you.

Here are a few videos that illustrate some of what I want you to think about:

Two teachers in the U.S.A. worked with their classes to come up with a list of guidelines for student bloggers.

One of them, Bud Hunt, has these suggestions, among others:

1. Students using blogs are expected to treat blogspaces as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. While we encourage you to engage in debate and conversation with other bloggers, we also expect that you will conduct yourself in a manner reflective of a representative of this school.

2. Never EVER EVER give out or record personal information on our blog. Our blog exists as a public space on the Internet. Don’t share anything that you don’t want the world to know. For your safety, be careful what you say, too. Don’t give out your phone number or home address. This is particularly important to remember if you have a personal online journal or blog elsewhere.

3. Again, your blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover some really hateful and immature things you said when you were younger and more prone to foolish things. Be sure that anything you write you are proud of. It can come back to haunt you if you don’t.

4. Never link to something you haven’t read. While it isn’t your job to police the Internet, when you link to something, you should make sure it is something that you really want to be associated with. If a link contains material that might be creepy or make some people uncomfortable, you should probably try a different source.

Another teacher, Steve Lazar, developed a set of guidelines in consultation with his students. You can read them here.

Look over the guidelines and add the ones you like in the comments section below this post; either from one of Steve's students or one of your own. I think Bud's suggestions are excellent. We'll be using the one's I highlighted above as a basis for how we will use our blog.

Cheers,
Mr. K.

I could not have written it any better. Enjoy blogging and use your head. Thanks

Mr. Harbeck

### Field Trip Question

Field trip in Akko_1151

Room 43 is going on a field trip. The seventh grade class traveled in four separate cars. The school provided a lunch of submarine sandwiches for each group when they stopped for lunch, the subs were cut and shared as follows:

• The first group had 4 people and shared 3 subs equally.
• The second group had 5 people and shared 4 subs equally.
• The third group had 8 people and shared 7 subs equally.
• The fourth group had 5 people and shared 3 subs equally.

When they returned from the field trip, the children began to argue that the distribution of sandwiches had not been fair, that some children got more to eat than the others. Were they right? Or did everyone get the same amount.

### Meet the Teacher 2007

Dear Parents and students this year is going to be an exciting one. I am looking forward to teaching your students math and having them engage in 21st Century learning. What is 21st Century learning. I define it as using the communication technology that your students love so much and having it be used to complete math assignments.

I want your students to communicate math as much as possible. I hope they will use their cellphones, videos, blogs and wiki's to learn in a fun safe environment.

Here is a movie that I created to introduce you to math in Room 17.

Parents and Students last year I started the year off with this post. It is still valuable and a good read. Enjoy the year.

Every year there is an opportunity to meet the parents of my students. I get to explain how my course is run and what expectations I have of the students and of parents.

Assessment in the course this year for the first term is based on test and quiz scores, journalling, completion of TLE-8 computer units, mental math activities and interaction with the classroom blog.

I like to give the parents a heads up on the positive aspects of blogging and the importance of the students being responsible for their actions.

Blogging is a very public form of communication. Bud Hunt, a teacher in the U.S. has these guidelines for his students. I will use them too.

1. Students using blogs are expected to treat blogspaces as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. While we encourage you to engage in debate and conversation with other bloggers, we also expect that you will conduct yourself in a manner reflective of a representative of this school.

2. Never EVER EVER give out or record personal information on our blog. Our blog exists as a public space on the Internet. Don’t share anything that you don’t want the world to know. For your safety, be careful what you say, too. Don’t give out your phone number or home address. This is particularly important to remember if you have a personal online journal or blog elsewhere.

3. Again, your blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover some really hateful and immature things you said when you were younger and more prone to foolish things. Be sure that anything you write you are proud of. It can come back to haunt you if you don’t.

4. Never link to something you haven’t read. While it isn’t your job to police the Internet, when you link to something, you should make sure it is something that you really want to be associated with. If a link contains material that might be creepy or make some people uncomfortable, you should probably try a different source.

One form of blogging work is Scribe Posts.

Scribe Posts

Write a brief summary of what we learned in class today. Include enough detail so that someone who was away sick, or missed class for any other reason, can catch up on what they missed. Over the course of the semester, the scribe posts will grow into the textbook for the course; written by students for students. Remember that as each of you write your scribe posts. Ask yourself: "Is this good enough for our textbook? Would a graphic or other example(s) help illustrate what we learned?" And remember, you have a global audience, impress them.

Students will be expected to contribute one scribe post every 30 classes or about 4 times a year.

Examples of Scribe Posts from last year.

LaraMae did a scribe post during our algebra unit. Her scribe included a picture that accuratly depicted a piece of paper that had been folded into 5 columns filled with notes. It was awesome.

Norielle through the use of one image described and explained how to find the surface area of a cylinder.

Josh showed how to find the volume of geometric solids in tremendous detail.

The Scribe Post Hall of Fame showcases the best Scribe Posts from around the globe. Our student figure prominantly on this site.

Another way we use our classroom blog is to create Growing Posts.

Growing Posts

Growing posts are like unit reviews. Each growing post starts off as one post by the student answering one question about a concept. Each day the students have to answer a new question and add it to their post. At the end of the unit they will have a comprehensive resource of material needed to study for tests or complete assignments.

Here are some excellent Growing Posts

Sometimes students strive for enrichment. Here is an example of intrinsic creativity
Aldrin's Fraction Growing Post

The Growing Post Hall Of Fame was created to allow student work to be displayed for the world to see. I am proud of the work that students did last year and am looking forward to this years inductee's.

This years classes will participate in many activities that will prepare them for their future. As parents enjoy their ride through the Sargent Park Math Zone of Room 17. If you dare come along for the ride with them!!

I showed the students this video today. Watch it and see where the world might... is going. It was made by a teacher K. Fisch from Colorado.

### Pythagoras Word Problems

Try answering these word problems. You can answer them here at the blog or at your class blog.

1. Tony has got his kite stuck at the top of a very tall tree. He knows the string on his kite is 20 m long. When he pulls the string tight and holds the very end on the ground it touches 17 m from the bottom of the tree. If the ground is flat, how tall is the tree?
2. Susan is making a jump to ride her bike over. She uses a 1m plank of wood to make the jump, and raises the end 50 cm off the ground with a second piece of wood. How far along the ground from the end of the plank that touches the ground is the second piece of wood?
3. Robert is using a 5m ladder to climb in his upstairs bedroom window. He finds that if he puts the base of the ladder 3.3m from the wall the top leans on the windowsill. How high from the ground is the windowsill?
4. The guy wires holding up an 11m radio transmitter join 2m from the top of the aerial, and are anchored to the ground 7m from the base of the aerial. How long are the guy wires?
5. Tim is standing across a river from Mary. They discover that if they stand exactly opposite each other they can each hold one end of a 5m rope. How long would the rope have to be to reach if Tim moved 8m downstream?

### Some Pythagoras work

Here are some questions you can do to practice your work.

Draw a picture to solve this question

Robert is using a 5m ladder to climb in his upstairs bedroom window. He finds that if he puts the base of the ladder 3.3m from the wall the top leans on the windowsill. How high from the ground is the windowsill?

June 14th Part 2 is due.(You will have access to the Math lab during the week of June 11th to 14th)

This unproject is part of the Term 4. It will be worth 10% of that terms mark.

### Instructions

Your job is to be an expert in 2 topics that we have learned this year. You will need to check your math portfolio to check the topics that we have covered.

1. Data Managemant and Graphs

2. Probability

3. Square Roots

4. Percent

5. Ratio

6. Proportional Reasoning

7. Fractions (only if you did not participate in the first Unproject)
