Good Afternoon Everyone!

I hope you had a terrific night! Monday is day 4 (Music, French and Gym). Please bring your gym clothes and shoes to school. 

Pancake Tuesday has been moved to Tuesday, March 5^th.  **Aftercare invoices have been sent out. Please pay your invoice by Friday, February 15^th to avoid interest charges**

**Please do not order lunch on the following days – March 7^th (third ski day) and March 27^th (Legislative Assembly field trip).** 

It seems as though the cold and snowy weather is here to stay. Please ensure that students are sent to school with proper outdoor gear - winter coats, hats, mitts, winter boots, scarves, etc. Students will not be allowed to stay in at recess if they are not dressed accordingly. I thank you for your support. 

Don't miss out on your chance to reserve your spot for our March Break Camp!!

Inquiry into Language

Today we had our second literature circle. While groups waited to be called to the circle, students studied for their spelling test. Great job on your literature circles Grade 5!

Week 2 - Chapters 18 and 19 - due Friday, February 22nd

HW - Read chapter 20 - due Monday, February 25th

Week 3 - Chapters 21-23 - due Thursday, February 28th

Inquiry into Mathematics

Today in math we reviewed surface area of a triangular prism, after marking last nights homework it was evident that students struggled with the concept. We went over our three steps into detail and took up some questions from last nights homework. Students started to work on their math homework sheets (front and back) of volume of triangular prism and surface area of a triangular prism.

**Remember when you are finding the area of the three rectangles it is not all the same for all three. For example from yesterday lesson: 15 x 9 + 15 x 10 + 15 x 9 = 420 cm squared. NOT (15 x 9) x 3.  The base and height of your top and bottom rectangle will be the same, meanwhile the middle rectangle will be different. To find the base you must look at your triangles to find your base of the rectangle as they are the same.**

Points to remember:

We are nearing the end of the lessons for this unit. We will finish the lessons this week and begin our review next week. Our math test will take place on Thursday, February 28^th.

The perimeter is the outside of a figure. For any polygon, you can find the perimeter by adding the side lengths. When finding the perimeter of an parallelogram, we can use a formula of P = (l + w) x 2! **To change mm to cm you will need to divide by 10 – move the decimal one spot to the left. For example, 108 mm would become 10.8 cm.**

To find the perimeter of a rectangle, we use the following formula – P = (l + w) x 2. To find the area of a rectangle, we use the formula – A = l x w. Don’t forget that when you convert a measure of area from square metres to square centimetres, each dimension is multiplied by 100, so the area is multiplied by 100 x 100, or 10, 000.

Parallelograms: Any side of a parallelogram is a base. The height of the parallelogram is the length of a line segment that joins parallel sides and is perpendicular to the base. In order to find the area of a parallelogram, we use the following formula: A = b x h. For example, 13 cm x 15 cm = 195 cm squared. When we are given an area and asked to find the height or base, we do the opposite. We take the area and divide by either the height or base. For example, A = 60 m squared and base is 12 m, then 60/12 = 5 m, therefore the height is 5 m. 

To find the area of a triangle we use the following formula – A = (b x h) / 2. The area of a triangle is one-half the area of a rectangle with the same base and height. For example, A = (2 x 6)/2 = 12/2 = 6 units squared. Please note that any side of a triangle can be its base. **The area of a triangle if one-half the area of a rectangle or parallelogram with the same base and height.**

**Remember when calculating area to use units squared.**

To find the volume of a triangular prism, we must first find the area of a triangular face, which is A = (b x h)/2. Once we have the area, we can find the volume of the triangular prism, which is A = base area x height. For example, if a triangular prism has a base of 6 cm and a height of 4 cm, with a base height of 10 cm then step one is A = (b x h)/2 = (6 x 4)/2 = 24/2 = 12 cm squared. Therefore the base area is 12 cm squared. Now we can find the volume = base area x height = 12 x 10 = 120 cm cubed. 

**Remember that when talking volume we use units cubes.**

To find the surface area of a triangular prism we follow 3 steps:

1. find the area of each triangular face (b x h) / 2

= (10 x 7) / 2

= 35 cm squared

Since there are two triangular faces we must multiply by 2

= (35 x 2)

= 70 cm squared

Therefore, the area for the 2 triangular faces is 70 cm squared

2. find the area of the 3 rectangular face (b xh)

= 15 x 9 + 15 x 10 + 15 x 9

= 420 cm squared

Therefore, the area of the 3 rectangles is 420 cm squared 

3. add the area of the triangles and the rectangles together 

= 70 + 420

= 490 cm squared

Therefore, the surface area of the triangular prism is 490 cm squared 

Unit of Inquiry

Today in UOI we created some First Nations art. We created wall hangings. We will display them on our walls once they are dry!

Summative packages have been handed out. Over the weekend please read the package with your student and sign and return it for Monday. We will begin summatives on Monday!
