Multiplication Story Problems

1. Take two dice and roll them. The numbers you get are your two factors. Figure out what the product is.
2. Create a multiplication story problem for the equation you created and solved in step 1.
3. Type your problem with the answer below as a comment.
4. Don't forget to put your name!

Math in the Real World

Today we had two parents come in and talk to us about how they use math in their job - a nurse and an accountant. It was very interesting!

What's something you learned from their visit?

Multiplication Tips

Multiplying by 0:

The answer is always zero.

Example: 0x3 =0    0x5=0 

Multiplying by 1:

The answer is always the other number that is not 1.

Example: 1x6=6     10x1=10    500x1=500

Multiplying by 2:

Look at the other number that's not 2 and double it!

Example:
2x4 =  (double 4; 4+4)     2x4=8

2x8 = (double 8; 8+8)       2x8=16

2x12 = (double 12; 12+12) 2x12=24


Multiplying by 4:

Double Doubles! Take 4 and split it in half. Multiply each number by 2 and then double that answer.

Example:

4x8 =

2x8=16
2x8=16
then add 16+16
= 32

4x7 =

2x7=14
2x7=14
then add 14+14
= 28

4x15=

2x15=30
2x15=30
30+30
=60

Multiplying by 10:

Same rule as multiplying by 1. Look at the number that's not 10 and multiply it by 1 and then add on a zero OR count up by tens.

Example: 6x10=  (6x1=6, then add on a zero) = 60

8x10 = (8x1=8, then add on a zero)=80

Working Away!

We are working on wrapping up our unit in social studies on Saskatchewan and the landscape. We have been exploring the ecozones of SK and discussing what the land was like before settlers started coming here and how the First Nations lived off the land and how it has changed today. We also had many great discussions throughout this unit about the treaties!

Fall Artwork

The grade fours made some fabulous fall artwork! First we picked leaves off of the trees. We placed them behind the paper and coloured over them to get their imprint. We used fall colours. Then we took black paint and made a tree. We used a straw to blow on the black paint to create branches. The trees are leafless as that is what happens in the fall. The background is filled with the leaves that were once on the trees.

Reading Buddies

Today we partnered up with the Kindergartens and Grade Ones to do some reading. We read Halloween themed books. Some of the grade ones even practiced their reading to us too!!

Grade Four, what did you like best about reading to the kindergartens and grade ones this morning?

Rocks and Minerals Research Project

Rocks and Minerals Final Project:

 

You will be creating a poster board presentation on a given rock or mineral. You will need to do research to answer the questions below. You will also need to have images that relate to your topic. When you are finished you will be presenting to the class.

My rock or mineral is: ________________

 

Answer the following questions and put on your poster board:

1.  Is it a rock or a mineral? If it is a rock, is it sedimentary, metamorphic or igneous?

2. Where is the rock or mineral mined in Canada?

3. What are all of the different uses for this rock or mineral?

4. How do you think the world would be different if that rock or mineral didn’t exist?

 

You should have these under headings on your poster board, it should be organized and clearly laid out.

Here are some websites that might be a good start to help you find your information:

Glimpse of the week and HOJA!

This week we worked  some more on rounding and estimation, a lot of students have improved so much on this week, it was a good thing to see! Next week it's mental math and 4 digit addition. In science we discussed the different types of fossils and are doing a science/art themed activity to go alongside what we learned. The students also got their book report project outlines and they are excited about it, I will give them their bags next week.

This week was wrapped up with a visit from the acapella group, HOJA. The students loved listening to all of their songs.

 
 

October is Paper Bag Book Report Month!

October's book report is a paper bag book report. Each of you will receive a paper bag from me. You need to do two things with the bag - decorate the outside and fill the inside, easy!

1. Outside of the bag
   The outside of the bag should have the following:

 One side - name of book and author with a drawing that is about the book.
 One side - setting --> when and where the novel takes place and drawings of the setting.
 One side - characters --> name(s) of main character, description and drawing.
 One side - 6 to 8 sentences describing the  main events of the book.

2. Filling the bag

 The bag needs to be filled with AT LEAST FIVE objects that relate to the book.
 I will give you index cards or you can make your own, to write down your explanation for each       object of why it is important to your book.
 If you cannot find an actual object, be creative and make it! Draw it, build it, use Lego, clay, etc.

3. Practice presenting your book report so you're ready to say it to your audience in class.

4.  Have fun and be creative!

Due on Wednesday, October 30th!

Ordering Numbers

Since we are ordering numbers, create four 4-digit numbers and put them in order from greatest to least.
*Make sure to put your name by your comment so I know who it is!

Back to School!

Well, day one and two are in the books for us all. They have flown by and I'm so proud of how well everyone has managed throughout the two days as patience is a major part of the first week back to school. Patience when organizing school supplies, patience when learning new routines and procedures, and patience to wait your turn to share in all the summer story excitement. Newsletters went out today to youngest and only children. Some things to remind everyone about in case you're reading this because you don't yet have a newsletter....

1. Playground grand opening tomorrow from 5-7. Parents can tour their childs classroom for the first hour and then there is a ribbon cutting ceremony and BBQ. We will also have our new school clothing on display and order forms will be available.

2. Green forms sent home need to be brought back on Friday.

3. The white demographic sheet with your child's conact info needs to be looked over, if any corrections need to be made please correct on the paper with a pen. Please bring the sheet back by Friday as well so all of our contact info on all of our students is up to date in the office.


Tomorrow we are learning about twitter and will be doing some exploring on our grade four twitter account! We will be starting our science unit on rocks and minerals and we are refreshing our math skills with some 3-digit number work.

That's all for now,

Mrs. Stefan

Class Trip

What did you like the best about the class trip? What did you think was interesting?

Day of Care - June 5, 2013

Yesterday afternoon we participated in the community event, Day of Care. Since we have built a relationship with Creighton Lodge through visiting them throughout the year, we knew we wanted to help them out on this day. We were put to work raking, weeding and bagging the debris. It turned out to be a beautiful day and with some lessons on how to properly rake and pull out a weed, the students did an excellent job! It was exciting to see the kids partake in the event. They really step up to the plate everytime we go there and their break in the shade with juice and cookies was well deserved! The ladies were very appreciative and talked to them all about how at the lodge they are welcome to visit anytime throughout the summer, that it doesn't just have to be during school time.

Today we talked about "paying it forward" and some of the students mentioned that this is a way they would like to pay it forward during the summer, by going to visit the residents. I sure hope some of them actually do because they are great little vistors when they are there!

Water Day Challenge

On Friday the grade 4 and 5 classes took part in the Water Day Challenge that was put on by a group of grade 6/7/8 students. These students have been working hard on projects around the theme of global citzenship. This group in particular created a variety of stations for the kids to go through that simulate what it is like in third world countries that have a lack of clean drinking water.

Here are some of the stations:
