Do You Like Board Games?

A fun way to wrap up a school year is giving students the challenge of creating their own board game. And boy…were these grade 3s up for it!

We wrote down the success criteria together and knew the game had to involve math in some way. The students completed their board games, playing their own game several times and then play each other’s.

The level of detail was incredible! Several groups even crafted their own playing pieces! Wow.

Have a look at their hard work!

Finally, we were pleased to see our poetry anthology arrive to our classroom. The students were delighted to see their published poems in a book that they can keep forever. What a great job everyone did!

What’s the Chance?

Over the last while, our students have been learning about probability.

What is PROBABILITY? It is the chance of something happening.

What better way to understand “chance” than by playing games? We started off by playing a Horse Race game which involved rolling 2 dice. If you rolled your horse number, you got to move. If someone else rolled your horse number, your horse moved. The first horse to cross the finish line wins! After examining patterns across each group’s board, we noticed that horse number 6,7,8 seemed to be winning the most. We learned that it wasn’t “luck” that made a horse win…it was math! Probability!

Last week, we also played a probability game called Race to the Top. Students used a spinner and recorded the results in a table/chart. Whomever made it to the top of the chart first wins! We first used a spinner that showed equal chances of winning. Then, we used a spinner that did not show equal chances of winning. Take a look at the fun we had!

In a World of Robots

Recently, as a culminating activity to our 3D Geometry unit, students designed their own robots and presented them to several other classrooms. Using an assortment of recycled materials, students loved making their projects and were proud to show off their hard work. They were asked to give their robot a name and write a paragraph explaining the features of their robot and the 3D shapes they used.

A Classroom Shopping Spree

What can one buy with only $10.00 to spend on various items around the classroom? That’s exactly what students had to decide when shopping around the room for various items with price tags. The rules were they had to spend more than $4.00 but no more than $10. Some students commented on the bargains to be had! It’s interesting to see the shopping habits of these young students already emerging 🙂 With clipboards and pencils poised, students carefully tabulated their totals. When we gathered back together to discuss and share, we also learned how to calculate change with a subtraction strategy.

We discussed what we could buy for  $10.00 outside of the classroom and the fact that in reality there is tax to be included in most things as well.

How would you spend $10…or would you save it?

Spring Has Arrived!

After March Break, time always seems to fly. We are in the season of Lent, moving closer to Easter. The students in our class have been working incredibly hard on their school work. We have been diligently studying and practicing our times tables. Mrs. Sullivan has been impressed!

As a class, we’ve been pushing ourselves to strengthen our Word Study test scores overall and the results have been outstanding!

Several students have been challenging themselves to achieve silver certificates in Mathletics. Wow! Who will earn the first gold?

We continue to move along nicely in our newest writing unit called Realistic Fiction where we are gathering ideas.

Take a look at some of the activity in our room as of late:

What do you like the best about Spring?

All in a Day’s Work…

There’s certainly never a dull moment in Grade 3. We work hard, do our best, and try to have fun at the same time.

Below, students are playing “Quiz, Quiz, Trade” to review for our Social Studies test coming up. Students could use their notes, if needed. They coached each other if they weren’t sure of the answers and then traded cards once each student successfully finished each card.

Here, students are reviewing subtraction by taking turns coaching each other through the step-by-step process. They did such a fantastic job!

Check out this awesome tutorial by one of our classmates!

Have a wonderful weekend!

Superb Subtraction

Our class has been spending a lot of time delving into 4 strategies about how to add 2 and 3 digit numbers. In the next few weeks, we’ll be sharing with you student-guided tutorials about how to use these strategies.

Yesterday, we launched into subtraction strategies. We learned how to subtract using a number line by “thinking addition”. See below for an example.

Today, we explored the traditional method of subtraction where “borrowing” or “regrouping” may be involved. Check out this video we watched in class that introduced us to the concept.

On Monday, we will explore a 3rd strategy. There are pros and cons to any strategy.Some are faster than others, some are easier to understand. Everyone has a favourite.

What is your favourite subtraction strategy?

Do you know how to solve a question in more than one way?

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?
