Mira Mira on the wall…

As we conclude our 2D Geometry unit, symmetry has been a more recent focus in math.

What is line symmetry?

• Symmetry is  a “Reflection” or mirror image. It means you can fold an image exactly in half so that one half matches the other half perfectly.
• We see line symmetry all around us, especially in nature.

Do you see symmetry in this bird?

A tool we’ve been using to help us create symmetry in pictures is called a Mira. Have a look at us in action creating a Grinch picture!

Angles All Around

In our 2D Geometry unit, we’ve recently been identifying 4 types of angles:

• acute (less than 90 degrees)
• obtuse (more than 90 degrees)
• right (equal to 90 degrees)
• straight (exactly 180 degrees)

We decided to go on a scavenger hunt around our classroom to find examples of each type of angle. Students then worked together to made a pic collage to show their findings. We had a lot of fun! Have a peek.

What kind of angles can you find around your house?

Venn Diagrams

Simply put, a Venn Diagram is a tool to help us sort things. A man named John Venn (a logician) invented them a long time ago.

Have a look below at the diagram.

We made some of our own Venn Diagrams using hula hoops and various objects we found around the class. Can you guess how we sorted the following items in the pictures?

You will notice one item (a clipboard) placed outside the Venn Diagram. That is because it doesn’t belong in any of the categories within the Diagram.

Students have been working in their teams to sort numbers as well. Have a look at the action. Click on individual pictures to enlarge them:

Recently, Mrs. Sullivan created a Venn Diagram with fiction and nonfiction books. Students had to guess how the diagram was sorted and find other books to add to the Venn Diagram.

What kind of items could you sort into a Venn Diagram?

Survey Says!

Data is all around us! We use data to learn about what to wear to school in the morning, we use it to learn from our mistakes, we use data to tell us how long it will take us to get somewhere. Data informs us and it can be very helpful in our lives.

Recently, we wanted to conduct our own surveys based on a question each of us individually made up. We were not allowed to ask ‘yes/no’ questions and needed to provide around 4-5 possible answers. Students also needed to push themselves to think of a question they truly wanted to know the answer to.

We were asking our question to all of the grade 3s at our school.

Some questions included:

• How do you typically get to school?
• How long do you usually spend on homework each night?
• What is your favourite sport?
• What time do you usually go to bed?
• What is your favourite type of unusual pet?

Check out the students asking each other their questions and recording their tallies! Next, we will graph the data in 2 different ways and share our results. What kind of conclusions can we make, if any?

What is a question you would want to know the answer to if you were to ask a Grade 3 student?

Never a dull moment!

There’s never a dull moment in our class! We’ve been so engaged in all aspects of our day–French, Math, Science and more. We enjoy working in different teams, sharing our strengths and gifts, nibbling on treats, learning about all sorts of things. Check us out!

Growing Patterns

In our current Patterning unit, students were learning how to create growing patterns today.

After discussing what a growing pattern is and looking at some examples, we put our knowledge to work!

• A growing or increasing pattern increases each sequence by the same amount each time

We love to build things so using either linking cubes or pattern blocks, students built their own growing patterns and then explained how it was growing.

Take a peek at some of the growing patterns the students created in class today! All students chose to grow shapes.

Patterns in the Classroom: Scavenger Hunt

We have recently launched our Patterning Unit in math. Today, to kick things off, we learned what an ATTRIBUTE is and then went on a scavenger hunt around the classroom hunting for patterns. Tomorrow, we will have each team share more about the patterns they discovered and explain the patterns to the class.

• An attribute is the way you describe an object such as its shape, colour, number of sides, size, direction, etc.

Where do you see patterns in the world around you?

Do you see any patterns in nature?

Mathletes Among Us

Mathletics is used as part of our math learning in class and is an online math program that helps us practice our math facts, reinforces concepts, and is FUN! Mathletics is available with 24 hour access which means that students can work at their own pace, anywhere, anytime. This online math tool helps us practice computation and improves our math fluency, especially when we use LIVE Mathletics. We love competing with one another!

Parents–If you haven’t already, it is recommended that you spend a little time looking at the program with your child so that you can gain the greatest understanding of how Mathletics will benefit his or her learning.

Take a quick video tour by clicking here!

How do I earn certificates?

A certificate is awarded to a student once they have earned 1000 points in a single week. Only one certificate is awarded each week, to help encourage sustained study by the student. Points are awarded across Mathletics in a number of ways…

• Live Mathletics – students earn one point per correct answer
• Live Mathletics – students earn two points per correct answers on their bonus level (indicated by a gold star next to the level number)
• Mathletics curriculum – 10 points per correct answer within individual activities
• Mathletics curriculum – 20 points per correct answer within a “Test”

If a student earns 1000 points in one week, they earn a Bronze certificate.

If a student earns 5 bronze certificates that earns them 1 Silver certificate.

If a student earns 4 silver certificates, they will earn 1 Gold certificate!

A maximum of 1 certificate can be earned per week. This encourages students to complete a healthy amount of work each week and rewards students for every week they practice.

Points reset each Sunday.

Keep up the great work, Grade 3s!

What Does Learning Look Like?

Learning is thinking, doing, playing, sharing, questioning, listening, exploring, and so much more! The photos above show our class doing many of these things. Learning can be so much fun!

Off to the Races!

PROBABILITY is the chance of something happening.  Recently, we played the game “4 Corners” where students have to respond to a question such as “What are the chances you will go out for dinner tonight?”. The students had to  move to one of the 4 corners in our classroom labeled “Likely” “Unlikely” “Certain” and “Impossible” and be able to justify why they were there.

Playing probability games is a fun way of exploring this notion of “chance”. One recent game involved a little bit of ‘horse play’. Students worked in teams to race across the gameboard by rolling 2 dice. First, they had to choose which horse they were going to be (from horse number 2 up to horse number 12).

Students were only allowed to move their horse (1 space) if they or another team member rolled their horse’s number! Students noticed that horse numbers 6,7,8 always seemed to be winning. How come? Was it luck? Magic?

After a discussion about the chances of rolling each number of a die, students quickly realized that there are more chances of rolling a 6, 7 or 8 which explained why those horses were winning more often! It wasn’t magic, afterall. 🙂

Here is a video explaining how we play Skunk in class. Note: when we roll snake eyes, we play the version where students would lose all points for the current round and PAST rounds too.

Where do YOU see probability around you?
