On your mark…get ready…COMPUTE!

In the enthusiasm and dedication to mathematical growth and thinking at the OJCS, we are bringing the Beaver Computer Challenge to all students grades 4 and above. Created by students, teachers, and professors from the University of Waterloo: The Centre for Education in Mathematics and Computing, this contest is open to students around the country and around the world, and we are SO EXCITED to be participating this year!

The Beaver Computing Challenge (BCC) introduces Computer Science through problem based questions. Students require no prior knowledge about computing, but rather work toward problem solving and using those “hidden” computer science skills for hands on learning and experience.

The contest is a 45 minute timed experience that involves a total of 12 multiple choice questions at 3 different levels, A, B and C.  “A” level being the easiest of the three, and then becoming more challenging with level “C.” Students complete the contest on their own devices, and are allowed a calculator and are encouraged to use pencil and paper to use the strategies taught in class to: draw a graph, make a table, draw a diagram etc.

There are two different levels of contests, one for grades 4-6 and another for grades 7-8. This ensures that the math curriculum and material provided is aligned with the contest material and methods of strategy and answers by grade cohorts.

This year, the Beaver Computer Challenge Contest will be conducted on NOVEMBER 9th 2021 at the OJCS. Grades 4-8 will be writing this contest on the same day during a scheduled time with their Mathematics teacher in class.

We are thrilled for our students to be a part of this exciting contest and experience. Students are encouraged to demonstrate participation over competition as they work toward improving their problem solving skills, as well as perhaps enticing some possible future computer programmers in our midst.

Math Upcoming Fractions Test

Hello, Grade 5 Families,
As we complete our section on fractions, we are looking to have a test on the material on Tuesday, May 11. Given that we are learning online right now, we will be completing a different style of a test than usual… an escape room! The escape room will be available on Google Forms and administered during class while Miss M., Ms. Michelle, and Mr. Kom will be available to answer questions. Students will be asked to answer the questions to solve the room. There will be class time given this week for review and answering questions. The review worksheets for practice will be provided for students to practice the necessary skills, which are located here.
The learning skills being tested are:
1. Adding fractions with like denominators
2. Subtracting fractions with like denominators
3. Multiplying fractions by whole numbers
4. Divide whole numbers by unit fractions
5. Reducing fractions to their simplest form using equivalent fractions
6. Convert between a mixed number and an improper fraction
Students are encouraged to practice problems on IXL, completing recommendations by Miss Mellenthin and Ms. Michelle.
We look forward to escaping the fraction factory with you!

An afternoon of coding with 5B

This afternoon students in 5B started the new math coding unit using code.org. They were engaged and collaborating with one another, helping each other reach new levels in problem-solving in Minecraft.


Another student took the time to present his completed self-built and coded (using youtube tutorials) moving robot. This was part of our Genius Hour project time.

Long Division – Math Quiz

We mentioned the new Math curriculum when discussing memorizing multiplication facts. Another new section within this unit is that students are now required to learn 3-digit by 2-digit division. In the past, learning 3-digit by 1-digit division was a new skill. Therefore, with this change, there’s a bit of a gap with the progression of learning, and our students need to learn both 3-digit by 1-digit division AND 3-digit by 2-digit division.

In the best of times, long division can be confusing. Therefore, we have made a few choices in terms of how we will be teaching and assessing this skill this term.

  1. Students have learned 2 different long division strategies — standard algorithm and division with repeated multiplication (see videos below). They have the choice to use whichever strategy they are most comfortable with.
  2. For our quiz on Tuesday December 15, students will also have the choice of which skill they demonstrate their understanding of. The truth is, that if you know how to do long division for 3-digit by 1-digit numbers, you likely will be able to do 3-digit by 2-digit as well. But we understand that it can feel overwhelming and tricky, and that’s the last thing we want to induce! Therefore, there will be 2 quizzes for students to choose from. Quiz A will focus on 3-digit by 1-digit division. Quiz B will focus on 3-digit by 2-digit division. Throughout the term, students who choose to do quiz A will have other opportunities to practice and demonstrate their mastery of 3-digit by 2-digit division.

To help review for this quiz, students already chose a practice worksheet to bring home as part of their homework this week. There are 9 questions in all, and we recommend they do 2 – 3 each night. We have also been checking in one-on-one with each student throughout the week to help them make the best choice as to which quiz they will be completing next Tuesday. This is a great step in independence and owning their own learning.

If you would like to see some of the strategies we have been learning, please watch the following videos. Students can also access extra practice worksheets here, and use IXL as a study tool.

3-digit by 1-digit Standard Algorithm

3-digit by 1-digit Repeated Multiplication

Checking Division with Multiplication

Math Quiz – 2-digit by 2-digit Multiplication

Over the last few weeks the students have been working hard on mastering the Standard Algorithm for multiplication. We will be having a short quiz on Tuesday, December 1, as a check-in before moving on to long division.

Here are some of the strategies we’ve been practicing so far that students have found helpful:

 

Using a sheet of paper to cover the number in the 10s place of the bottom number (multiplier) has also been helpful in reducing confusion as they multiply the top number (multiplicand).

Every student received a review package in their homework this week. They can also access MANY review worksheets here.  IXL continues to be a great place for review, and tasks specifically related to multiplication have been assigned.

The Facts About Multiplication Facts

As some of you may know, Ontario released a new math curriculum in 2020. There are a few new strands, such as financial literacy and coding, but one major philosophical change is the requirement for students to memorize their multiplication facts. In grade 5, students are required to learn their facts up to 12 x 12.

I have written about memorizing facts before, and have participated in workshops on online webinars to learn other strategies for helping students learn their facts. I personally believe that there is a balance between memorizing and learning the “why” of multiplication. I don’t believe it’s an all or nothing, you just know them or you don’t, kind of thing. There may be some facts that come more easily, and others that are more difficult. Using strategies to make those more difficult ones make sense seems so much more beneficial than simply just memorizing it.

With all that being said, the one common strategy, whether you are learning or memorizing, is practice! Talk about multiplication, think about multiplication, practice multiplication, make it a part of your daily routine, and it will get easier! Therefore, over the next number of weeks, in addition to reading daily, students will be required to practice their multiplication facts until they are mastered. Some may already be there, some may need until the end of the year. Either way is perfect! Students will have the opportunity to demonstrate their mastery whenever they are ready, fact by fact.

Think About Multiplication

I highly recommend watching this webinar (it’s about an hour long) for some ideas about how you can talk about the facts to help your child learn those trickier ones.

Read About Multiplication

Here are some strategies from a book I got at the Scholastic Book Fair two years ago, Math Hacks by Vanessa Vakharia (if you follow the link, there are some suggestions for online sites and games for practice)

Practice Multiplication

  1. Make Flashcards. This is much better than buying them premade! Writing the facts down is in itself a form of practice. Students can cut the cards, write the multiplication sentence on one side, and the answer on the back.
  2. Math rap songs. For our auditory learners, listening to songs about multiplication and adding a beat to it can be helpful. Students can learn all the newest pop songs by heart…why not their multiplication facts? YouTube has tons of options. You just need to find the one that appeals to you. Here’s a site with 30 fun ideas that play on your musical, artistic, or kinesthetic learning style.
  3. Online multiplication practice. These are a few suggestions but there are TONS to choose from.

    2. https://www.multiplication.com/games/play/quick-flash-ii
    3. https://www.timestables.com/
    4. https://www.coolmath4kids.com/quizzes/multiplication
    5. https://webmathminute.com/online
  4. Printed practice sheets. I have heaps of practice sheets that students can take home.
  5. Find tricks to help you remember your facts.
  6. Mrs. Cleveland has also created a list on her math blog, to many different useful math practice sites, not only just for multiplication.
