Recently students from Division 5 and 3 had a presentation from ERASE BC about online safety.  They learned about good digital citizenship practises and how to keep themselves safe online.

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

On Wednesday we had a visit from the Burnaby Art Gallery and students had the opportunity to explore artwork that incorporates BC’s coastal landscape. We looked at the artwork of artists such as Toni Onley, who has spent years documenting the coast of BC using watercolours, etchings and drawings; and Gordon Smith, who had a life-long fascination with BC’s rugged coast. We learned how artists use colour and atmospheric perspective to show the stillness of undisturbed coastlines. We also learned about watercolour and used mixed media collage techniques to create an art work that is influenced by our own connections to the environment.

In Art students have been learning how to use shape as an element of art and created shape cities.
