Grade 8 SJCC Pool Prototypes: Real Life Math in Action!

Grade 8 has been busy working on their SJCC Pool Budget Proposals!

We’re getting down to the final expenses in our spreadsheets. It’s been a long yet meaningful process connecting all of our math strands to find the cost and amounts of “re-vamping” the outdoor SJCC pool and even adding a circular hot tub! Real Life Math in Action!

Students had to use scale models to find:

  • All costs of the pool for 3 months plus reno costs; such as the following:
    • electricity
    • water delivery
    • water charge
    • re-paving
    • re-tiling
    • painting
    • fencing
    • water consumption
    • evaporation rates
    • employees
    • employee E.I. and CPP Contributions
    • membership costs and possible algebraic equations to break even and make a profit
    • Taxes
  • Along with a graphed analysis when the budget proposal is complete, students also had to construct and make a scale model “prototype” of what their pool may look like.

Great work guys and gals! We’ll be completed the entire project in 2 weeks!



Did You Know? Mrs. Cleveland has been busy!

Did you know that I have been planning the OAME (Ontario Association for Mathematics Education) conference for the past three years! and….tick tock…it’s now happen in just mere days! Yep! A whole province wide conference!!

We have over 1500 attendees of teachers, professionals and educators from across Ontario, as well as over 500 speakers and presenters from around the world visiting the conference for just over 3 days! WOW! It’s been so much work, but it’s been so worth it! Also, being able to work so closely to the one and only Marian Small, (who is the Head Chair) has been an absolute delight and experience I will treasure forever!

OAME 2019 is happening in Ottawa this year May 16-18. With my role and positions on both the board as a chair on this planning council, and with my executive role and position on the local board COMA (Carleton Ottawa Mathematics Association), soon to be O34ME, places me in an amazing position to not only prepare, organize and implement this conference, but also as my role here as Math Specialist at the OJCS, to bring some of my wonderful colleagues along to participate in many of the hundreds of sessions and courses being offered.

Mrs. Thompson, Mr. Kom, Mrs. Bennett, and Ms. Krantzberg will all be attending many wonderful and meaningful sessions this week at Ottawa University during the conference on Thursday and Friday. I am so proud of my colleagues and so look forward to learning with them, and bringing new ideas, inspiration, and math moments back to the OJCS!

Some of the sessions in which they will be attending are the following:

  • Harnessing the Power of Assessment in Mathematics
  • Number Structure: Reconceptualizing NUmbers with Depth, Breadth, ad Complexity
  • Creating Mathematical Possibility by Constraining Mathematical Possibility
  • Structures for Differentiating Middle Years Math
  • Teaching on the Edge of Understanding and the Speed of Learning
  • Teaching for Mastery
  • Improving Teacher voice in the Math Classroom
  • #slowmath: Reflecting, Connecting, Communicating
  • Strengthening Math Instruction and learning trajectories in K-1
  • Building Fluency in Junior and Int Grades
  • Math Thinking using Code
  • Personalized Learning Environments in Math
  • What does Understanding and Thinking actually look like as fundamentals in K-8 Math.

We will also be tweeting out and sharing our learning experience with our fellow colleagues here at the school as well as the greater digital community as we all continue to grow our own Personal Learning Networks.

You can follow all of our learning and time at this year’s conference by following the Twitter Hashtag #OJCSlearns, and also by following myself @mathemachic Mrs. Thompson @melissa_thomp Ms. Krantzberg @LKrantzberg

Can’t wait to have you all follow along with us as we bring the best math practices and techniques back to our classes to make math meaningful and momentous at the OJCS!

Yours in Mathematics,

Mrs. Cleveland


8W: Math and Science – Let’s make a Kiddish Cup!

Hi Grade 8!

Mr. Ray and I are joining forces for a bit to help support you with designing, planning, and creating your own Kiddish Cup using the Blender Software and 3-D Printer! Here is Mr. Ray’s rubric for your project.

To find the area of a cylinder you need to multiply the area of the base x the height of the cylinder.

Take a look here.


To help you find the volume of your internal cylinder. Here is a video (same from class) to help.

Also, don’t forget if you are provided the required volume in oz. You need to find a conversion to cubic centimeters. You can find an online conversion calculator here.

Once you have the volume required in cubic centimeters, now you are ready to work backwards to find your heights and radius!

How? Here’s a helpful sheet to help you work backwards!






7C: Math Escape Room

Hey there grade seven!

What a great afternoon we had yesterday, escaping from the math class! We shortened our time from 60 mins to 40 minutes because of STEAM fair preparation, but we still had fun solving clues and working together, and persevering to find the correct solution.  What I overheard at the beginning…”I can’t” “It doesn’t make sense” “there is no solution” was how knew you were in the right “uncomfortable” space for learning.

It was hard for me to #notstealyourstruggle…..but I did it…and more importantly YOU did it! Ending the class with lots of “We did it” “OMG, we got the answer” and “Can we do that again” shows me your progress and again…more importantly, YOU should feel better for getting there yourselves! Way to go!!! and thank you to the teachers that popped in to watch this exciting lesson and experience in action! You are always welcome!

I’m already thinking of the next Escape Room to plan for you!!! Stay tuned…..



8W: Escape Room in Pictures

Great morning yesterday grade 8!

You were engaged and on task as you went through solving four clues to “escape” the math class. Great to see that you used all and anything in the classroom to help you succeed. It was hard for me to step back and #notstealYOURstruggle. So proud of you!

Congratulations to all of you, escapees!!!

Take a look at our morning in pictures. Looking forward to making a new one for you soon!






Exams Sent Home!

Hi Middle School!

Mathematics exams were passed back today, and gone over in class. Please take them home over the break, and have them signed by a parent/guardian and returned the first week back after the February Break!


Have a wonderful and relaxing February Week!!!!!! ENJOY!



Problem Solving Across the Grades

In grades four through eight, students have been working and building their problem solving skills in their own math classes and with me when I come in to support the teacher and students as the OJCS Math Coach.

Knowing What to do when you don’t know what to do is a concept that I’m working on very closely this year with my middle school students and also modeling as I co-teach and work in grades four and five.

Over the past two weeks, each grade had a mini-math workshop around these skills. Structured as a “Thinking Classroom” and in a 3-Part learning arena, students were able to explore what they knew for their grade level and apply their age and grade appropriate skills to solve the exact same problem.

The workshop began with a “Minds On” activity around balance and equality. How do you know something is equal? How can you prove it? Such examples to get the brain juices flowing were: 3+1 = 4. Agreed. 2+2 = 4. Agreed. Therefore 3+1 = 2+2. This skill is a concept of variables and equal expressions used in algebraic thinking in grades 6-8. However, there is more than one way to always answer and approach a question and problem. We went over and followed the problem solving steps to help guide any problem you’re trying to solve.

The “Action” portion of the workshop involved small groups working on problem solving of an unknown question, but having to do with “something about making sides equal. This problem allowed students in all grades 4-8 to tackle and use their thinking skills in a way that supports our spiral curriculum. Learning and building on similar concepts each year and putting them into use. Two versions of the same questions were offered to support and foster personalized learning. Students were open to answer one or both. Students in grades 4 and 5, used logic, guess and test, and fraction equivalents to solve and prove their answers, while students in grades 6-8 used equivalent ratios, fractions, percents, common multiples and some even created algebraic expressions to come to their solution.

The end result, a fun filled class of squirmin’. When kids are squirmin’ they’re learnin‘.  When the students don’t easily know an answer, and if it’s something that intrigues them, we try to have them “sit” longer with the work to figure it out. The rooms and classes, in all instances, were full of math talk, collaboration, critical thinking, and excited mathletes that focused on their own solutions and proofs with enthusiasm and a love of learning.

Sound too good to be true? Check out the these images!



To conclude each of the workshops I conducted with each class, the students each ended with a reflection of what worked, what didn’t, and learning any new strategies that others used to solve the problem. At the end of all sessions with the middle school classes, I took students on a gallery walk to the display I had created in the upstairs hallway, which displayed all the work of all the students. It was THEIR work, THEIR learning, and THEIR growth. They didn’t want to leave, as they kept talking about it, seeing connections to what others did and how others in other classes and grades went about the problem. Reminiscing about “We used to do that in grade 4.” or ” What does unit rate mean? Can we learn that, too?”  (Even spotted and overheard discussions by the bulletin board during recess times).

Math is fun!

So….are you interested in what was it that got your child and/or our students engaged and thinking?

Want to try it out yourself? Well… here’s the problem that they all solved in their own ways

…..how would YOU solve it?

Please share your thoughts and ideas in the comments as we build our strategies as learners together! 🙂
