Day: March 19, 2018

Hello All!

I am looking for old magazines that you are no longer using at home and that are appropriate for grade 3’s to flip through – if you have any old magaizines that you don’t need back, please send them in! We will be cutting out words and ripping out pieces of coloured paper from them for an upcoming Earth day art project soon!

THANKS!

In math class with Ms. Argue, students have been using their rulers to measure lots of different things in our class!

Tonight, you will see a practice worksheet coming home in their grey math duotang that students had to complete before the March break in order to practice some of the concepts we have learned in our measurement so far. In our grade 3 class, we use the metric system and students are measuring things in mm, cm, m and km. Some of the concepts that they have learned so far is how to choose an appropriate unit when measuring something and drawing a line or shape using a ruler when given specific dimensions.

Please sign your child’s worksheet and help them correct any mistakes they might have to ensure they understand these concepts that we have covered so far. If your child brings it back corrected and signed, they get a chance to earn $200 to their class bank account! This was just a practice worksheet and does not officially count as a mark – I just used it to see where all of the students were and what we needed to still work on.

Next Tuesday, March 27th, students will be having a quiz in Measurement on the following concepts listed below. We will be reviewing perimeter tomorrow and moving onto learning how to calculate area this week. Students have been exposed to perimeter and area when working on their mental math sheets in their blue duotang but we will be looking at how to calculate both in more depth this week. Today we talked about how perimeter is the distance around the outside of a shape and area in the number of square units used to cover the inside of a shape.

– compare standard units of length (i.e.,
centimetre, metre, kilometre) (e.g., centimetres
are smaller than metres), and
select and justify the most appropriate
standard unit to measure length;

– estimate, measure, and record length,
height, and distance, using standard units
(i.e., centimetre, metre, kilometre) (Sample
problem:While walking with your class,
stop when you think you have travelled
one kilometre.)

– draw items using a ruler, given specific
lengths in centimetres (Sample problem:
Draw a pencil that is 5 cm long)

– estimate, measure, and record the perimeter
of two-dimensional shapes, through
investigation using standard units (Sample
problem: Estimate, measure, and record the
perimeter of your notebook.)

– estimate, measure (i.e., using centimetre
grid paper, arrays), and record area (e.g., if
a row of 10 connecting cubes is approximately
the width of a book, skip counting
down the cover of the book with the row
of cubes [i.e., counting 10, 20, 30, …] is
one way to determine the area of the
book cover)

Please let me know if you have any questions!

THANKS!
