This integrated unit involved:

ADST -prototyping, food safety, and making their pizza to show creativity, originality, and bold flavors.

Math-financial literacy (budgeting).

Health-Nutrition and menu/recipe planning and the exploration of healthy/unhealthy ingredients.

French-food vocabulary and how to order pizza in French.

Students really enjoyed planning for this activity and made some incredible pizzas. The whole school smelled amazing and the judges were left salivating over their final creations. Once the pizzas were judged, students got to enjoy their final creations. They all turned out great and there was very little if any remaining pizza. Well done Division 3!

PRIME & COMPOSITE NUMBERS

In class, we learned how to determine if a number is prime or composite. Prime Numbers have only 2 factors whereas composite numbers have many.  All even numbers are composite except the number 2.  The number 2 is the only even number that is prime because it only has two factors 1 and itself (2).  The number 1 is neither prime or composite where it’s only factor is 1.

To determine if an odd number is prime or composite we learned to apply the divisibility rule for 3.  If the sum of the digits is divisible by 3 then the number is composite.  If the sum is not divisible by 3 the number is prime.

Example:  27 (composite)                          18001 (prime)

2 + 7 = 9 – is divisible by 3         1 + 8 + 0 + 0 + 1 = 10 – is not divisible by 3

LOWEST COMMON MULTIPLE (LCM) & GREATEST COMMON FACTOR (GCF)

In class we’ve also been learning how to identify the Lowest Common Multiple (LCM) and Greatest Common Factor (GCF) of two numbers.

Example:

4 and 36

4: 4, 8, 12, 16, 20, 24, 28, 32, 36

36: 36, 72, 98

LCM = 36

Factors of 4: 1, 2, 4

Factors of 36: 1, 2, 4, 6, 9, 18, 36

GCF= 4

Today we went on a virtual field trip to the Bank of Canada we learned about money, trade, different forms of money, bartering and much more. Here is everything we learned today with the Bank of Canada.

Why do we use money?

1. As a Tool for Trade

2. To Set value (to know how much things cost)

3. To Save (Save up for needs/wants/emergencies)

What makes good money? Good moneys is…

1. Durable
2. Portable
3. Divisible
4. Rare but not too rare
5. Difficult to counterfeit

What is Dentalium?

• Sea shells used 200,000 years ago to trade
• Found on the coastline of the Pacific Ocean
• To retrieve you must dive for it
• Also used for decorations or jewelry

Which Canadian coin has a beaver?

Answer: The 5 cent coin

What are our bank notes made of?

• Bank notes used to be made out of paper but now they are made of polymer
• Polymer is hard to counterfeit because it’s made in a lab
• Polymer bills are recyclable when bills are taken out of circulation

Who is on the 10$ bill?

Viola Desmond

• First women to appear on a bill in Canada other than the Queen
• First person of color to appear on a Canadian bill
• Viola Desmond is a  Canadian human rights/social justice activist
• She is also a Business woman/Entrepreneur and opened a beauty school in the 40’s

Why do coins have different images/shapes/colors?

To easily differentiate them.

Money/Trade

• Money takes different shapes/ forms
• Money is a tool that we use to trade

What is Bartering?

Barter – Trading objects without getting something new.  It is obtaining a need or want by exchanging with someone else.

The cons of trying to Barter

• could be counterfeit
• sometimes its not a fair trade
• determining value/fairness can be hard
• money helps us determine value when trading
• finding someone to trade with can be difficult

Products vs Services

Products – grow it, build it or make it

Services – action someone does for us

Video: Navigating Mazes With Sphero

During Tech Day on Thursday, our class constructed mazes out of cardboard in small groups.  We then had to code Spheros to navigate through the mazes without touching the walls or running into any obstacles. Some of the challenges we faced were constructing the obstacles within the maze and then coding the Spheros to be able to navigate through the maze.  We had to learn how to adjust the speed, distance and angles to get the Spheros to navigate successfully through our maze and over ramps and bridges. We also had to learn to work together and divide tasks equally so that everyone was able to participate and take turns coding.

This past week students learned how math and art are sometimes intertwined during this Japanese Notan lesson. Japanese Notan design principles require the artist to use lines of symmetry and reflection to create positive (light) and negative (dark) spaces within their artwork.

During the first week back we read the book “Say Something” by Peter H Reynolds. The central theme of the book is that the world needs your voice and that a single voice can make a big difference.   Following the reading of the book students were tasked with making cursive name creatures and asked to use their voice to say something to inspire others. Don’t forget the world needs your voice too so don’t be afraid to use it.
