What's a Conjecture?

A conjecture is “an opinion or idea formed without proof or sufficient evidence” but with good reason, in other words or, it's providing a “reasonable guess”. We make conjectures in all subjects not just mathematics and we can use different vocabulary for each strand to help our students understand what they are doing when they make a conjecture. A visual that we discussed is an umbrella with “Conjecture” as the overhanging idea and different synonyms to help our students be aware of vocabulary they can use for the different subjects. 

Moving along with our Math Adventure, we are developing a clearer understanding of what is needed for students to demonstrate their ability in Reasoning and Proving. Students are being exposed to the Success Criteria for Reasoning and Proving best suited for their age group. 

Here’s an example with language that can be used in a variety of age groups:
Success Criteria for Reasoning and Proving  
1.    Make a conjecture (Reasonable Guess)
2.    Explain why you made this conjecture and give reasons for your thinking (Justify)
3.    Use manipulatives (objects) to show your thinking in more than one way (Prove)

 A "Conjecture Umbrella"

   Remember to come out to our Family Math Mania Night on April 6th to learn more about all this and how you can help your children make reasonable conjectures at home....

A Message from our new Principal!

We welcome Westminster's new Principal, Mrs Murray. Please see her message below: 

My name is Melissa Murray and I am thrilled to be joining the staff of Westminster Public School as Principal in January of 2018.

January is Tamil Heritage Month

On October 5, 2016, Motion M-24 was passed in the Federal Parliament, officially proclaiming January of every year as Tamil Heritage Month.  Tamil Heritage Month aims to celebrate the richness of the Tamil language and its literature, as well as to highlight the vibrant traditions, histories, arts, and cultures of Tamil Canadians. In addition, it seeks to recognize the significant contributions of Tamil Canadians in key areas of social, cultural, economic, and political spheres. 
According to the Tamil calendar, January 14, 2017 is the start of the Tamil New Year during the month of “Thai”. On this day Tamils around the diaspora will be celebrating Tamil New Year and Thai Pongal, the Tamil harvest festival. 
Thai Pongal is the most important and widely-celebrated festival amongst Tamils around the globe. Thai Pongal is a time to give thanks for the blessings of the previous year and a time to look forward to the New Year. Pongal refers to rice cooked in milk and sweetened with chakkarai…

Character Assembly on "Integrity"

Our Character Assembly this month will be focusing on "Integrity". Throughout the month, our students have been discussing what integrity means to them in the classrooms and with their friends in the school yard. Our students are learning that to have integrity means to be truthful and sincere; to care for the well-being of others by how they treat each other. Displaying integrity is not always easy. It is one of our most difficulty character traits to live by and sometimes it takes years to truly understand what it means.

We look forward to honouring those students who have displayed this trait at our awards assembly on Wednesday, October 28th at 11:15 a.m.

Parents and guardians are welcome to join us.  We thank Mr. Clark and Ms. Croteau's grade 2/3s for hosting the assembly this month.

"Integrity is doing the right thing even if it's difficulty; even when no one is watching." 

"If it is not right do not do it; if it is not true do not say it."
