Our World, Our Numbers Topic 5- Animals

Posted on by

This week, in our global blogging project, the classes are talking about animals from their countries.  Here is the post we added:

 

Here in Canada we have many different kinds of animals. Canada is a very large country and there are several different habitats that animals can live in. We have arctic, temperate rainforest, grassland, desert, coniferous forest, ocean, mountain, lake, river, and pond habitats.

We each chose a favourite Canadian animal to learn about and share with you. We will tell you about their length and height in centimetres or metres, their weight in grams or kilograms, and their lifespan in years.

We just thought that we should let you know that even though all these animals call Canada their home, hardly any of them live on our island! In Sointula, you will find White-tailed deer, Killer whales, and the occasional bear or cougar that swims across from the main land (this hardly ever happens).

Which Canadian animal is your favourite?

What kind of habitats are in your country?

Do you have any of these animals where you live or any animals that are similar?

Our World, Our Numbers-Topic 2

The second topic in the, Our World, Our Numbers project is landmarks. This topic is being led by Mrs. Yollis’ class in California.

We talked about Canadian landmarks earlier this week, but the students had a hard time thinking of any. Someone thought, the Co-op might be a Canadian landmark (it may very well be a landmark in our little town, but it doesn’t quite make the list). We also had suggestions of the Taj Mahal, the Sphinx, and Burj Khalifa (the world’s tallest tower). It seems we had a little work to do before we would be able to share with our friends around the world.

We started by looking at photos of famous Canadian landmarks and then read facts about each one. On Thursday, we choose the landmark that we would like to share and wrote our scripts with our partners. Next we practised, practised, and practised some more until we felt ready. After lunch we each took a turn in front of the green screen and put our video together just before we went home for the day.

Here is the video we made about Canadian landmarks:

 

Have you seen any of the landmarks we shared in person?

Are there other Canadian landmarks that you would have included?

Our World, Our Numbers-Week One

The first week of the Our World, Our Numbers project flew by!  You can read all the posts by the different classes by visiting the Our World, Our Numbers blog.  This week we learned all about Canadian, American, Australian, New Zealand, and UK currency.

Yesterday we tried a game called, “Guess My Coins” that Mr. Salsich and his class posted on the blog.  It was a lot of fun.  Theygave us 5 challenges to try:

  1. I have seven American coins that equal 67¢. What coins could I have?
  2. I have five American coins that equal 36¢. What coins could I have?
  3. I have nine American coins that equal 59¢. What coins could I have?
  4. I have seven American coins that equal 46¢. What coins could I have?
  5. I have eight American coins that equal 65¢. What coins could I have?

    Here is a video showing some of the solutions we came up with.  We thought it was great that many of the challenges had more than one correct solution.

     

    Do you have a coin challenge for us to solve?

Make 10

Today in math we talked about another math strategy that will help us with our basic addition facts. We used our special 10 frame cards to learn about Make 10 or Bridging to 10. Make 10 will help us with facts like 8 + 4 and 9 + 5.

Here are two great ICTgames you can play to practice the Make 10 strategy:

Bridging

Space Jumps

If you still need practice with number bonds for 10, here are 2 new games you might like to play and links to the 2 games we tried in December:

Missing Number

Math Lines

10 Pipe

A Number Many Ways

Today, after our number warm up, we were each given a number to show in as many different ways as we could. Sometimes we do this as a class with the same number and sometimes we each get our own number and do it on our whiteboards.

You might see us showing our numbers:

  • in standard form
  • in expanded form
  • in words
  • in a place value chart
  • using base ten blocks
  • as a base ten name
  • with money
  • as a greater than or less than expression

Can you think of any other ways we could show our numbers?

Clockominoes

Today we learned a new math game called Clockominoes. We all got a game board to bring home so that we can try it with our families. Sometimes you can finish your clock quickly and sometimes it takes all of your dominoes. How lucky are you?

Here’s how to play:

All About 14!

Every day when we finish our math warm up we do a number chat about a different number. Sometimes we do as many different equations as we can, sometimes we show a number as many different ways as we can, and sometimes we do both.

Today we did equations for 14. We could use addition, subtraction, multiplication, division, or combinations of the different operations. Here are our equations for 14:

Math Games For Home

Today your child will be bringing home a set of dominoes to play with you. We hope that you will enjoy playing some of the Box Cars and One-Eyed Jacks games that we play at school.

This week’s math game is called Domino Battle. Here is a great video made by Suzanne Weider, a 1st Grade teacher at Seth Paine Elementary in Lake Zurich, Illinois, explaining how to play:

Variations:
1. Subtraction Battle- Players draw a domino and subtract the pips (dots). The player with the least difference captures the domino.

2. Multiplication Battle- Players draw a domino and multiply the pips. The player with the greatest product captures the dominoes.

3. Place Value Battle- Players draw a domino and make a number in place value (tens and ones). The video below shows a few of us playing Place Value Battle.

Unexpected Results!

We continued working with our pumpkins this afternoon. We started by weighing them and found out that pumpkins A and B both weighed 5 kilograms (11 pounds) and pumpkins C and D both weighed 4.5 kilograms (10 pounds). We weren’t expecting a tie for heaviest and lightest.

What was even more surprising was the number of seeds we found in each pumpkin. You would think that the larger pumpkins would have more seeds, but that was not the case! Here are the results:

Pumpkin A -> 71 seeds (largest seeds)
Pumpkin B -> 190 seeds
Pumpkin C -> 583 seeds (smallest seeds)
Pumpkin D -> 172 seeds



After cleaning out the pumpkins and counting all the seeds, it was time to turn our pumpkins into jack-o-lanterns. Sue, Bonnie, and Elise helped us with the carving after we planned out our designs.





A huge thank you to Sue, Bonnie, and Elise for all their help!
