Math Strings

Math Strings….

You are likely wondering what a math string is…..  It is mental math!

In class, I will put a question on the white board.


Math String #1

20 + 30 =

Students will quickly develop strategies that help them answer this question in their mind.

Some strategies might be….

  1. 20 + 20 + 10 = 50
  2. 30 + 30 – 10 = 50
  3. 2 + 3 = 5 (then add a 0) and the answer is 50.
  4. ______________________________ (Create a number line and count by 10’s)

Math String #2

30 + 21 =

Again, students will quickly thing about strategies to answer this question in their mind.

Some strategies might be…

  1. 30 + 20 = 50 + 1 = 51
  2. 3 + 2 = 5 (then add a 0) to get 50 + 1 = 51
  3. ________________________________ ( Creat a number line, count by 10’s and + 1)

Math String #3

30 + 29 =

…. Again, students will develop quick mental math strategies to answer this question, without having to stack the questions.

You can try these at home and have your child describe different strategies they use to answer a math string!

February Measurement

Dear Families,

For the past two weeks, in between all of the inclement weather days, our class has been working on linear measurement.  We have focused on millimeters, centimeters, meters and kilometers.  At home, you can continue to practise converting millimeters to centimeters, centimeters to meters, meters to kilometers.  We will have our quiz on Friday February 8, 2019.

Starting next week, February 11 – 15th, we will be learning about area and perimeter.  Area is the inside area of a shape and perimeter is the distance around a shape.

Things you can do at home!

  1.  Calculators – We have started to learn how to use calculators in class.  This is new tool for many students.  It would be great if you could practise giving your child some addition, subtraction and basic multiplication questions for them to answer using a calculator.
  2. Continue to work on basic number facts (addition, subtraction)
  3. Measurement – Converting metric units (mm, cm, m, km) and have your child measure objects around the house using a ruler to the nearest mm and cm.


Christmas Holiday Open House

On Tuesday December 18, 2018, Worsley Families are invited to the Worsley Christmas Holiday Open House.  The open house will begin at 5:30 and end at 7:00 p.m.  The grade 3 classes will be singing Dashing Through The Snow – A Canadian Jingle Bells at 6:00 pm in the gym.  Students are encouraged to wear red and white, or Canadian clothing.  As well, if they have accessories that would help with possible Canadian animals, that would be great.

There will be a variety of activities happening tomorrow night.  It will be a festive evening.  Looking forward to seeing you all there.

Peppermint Frost

I am pleased to introduce you to Peppermint Frost.  Peppermint arrived in our classroom on Monday.  Peppermint is a math elf, who has many wondering math questions.  We look forward to see what math nonsense Peppermint get’s himself into each night.  On Tuesday, Peppermint was all wrapped up in a number line.  Today, he was in the corner playing horse races.  Hummmmm…. I wonder what math situation he will get into tonight?


12 Days of giving

Hello Families,

The staff and students at Worsley are participating in the 12 Days of Giving again this year.  Our 12 days of giving started on Monday December 3rd.   Each student is encouraged to help support this initiative.  Recognizing there are 12 items, whatever items you think you could help with would be a support to our local foodbank.   Listed below are a list of items that were collected this week.  You can always send items in that were already collected.  Our goal for this initiative at the school is to help others.

Monday – Canned Fruit

Tuesday –  Canned Tuna

Wednesday – Canned Soup

Thursday – Cereal

Friday – Cookies

I will update the items for next week when I find out what they are tomorrow.  Thank you for you support.  It not only helps our students understand the gift of giving, but also helps our local families in need.  You are all super heros!

Box Card Fundraiser

Hello Families!

Last week a box full of greeting cards was sent home with youngest and only children at Worsley.  If you received a box of cards and you are wishing to purchase them, please send back your payment in the white envelope that was provided in the bag with your boxed cards.  If you wish for another box, please send a note in your child’s agenda and I will arrange to have another box sent home.  If you do not wish to participate in this fundraiser and you do not wish to purchase the box of cards, please send the box of card, bag and contents in the bag back to the school as soon as possible.

This fundraiser will help to support learning opportunities for our Worsley students.  Thank you for your support.
