Dis-, Dif-, In-, Im-, Ir- and Il- Words

Below is a list of words we have studied for a number of weeks. We have segmented the words into morphemes (parts of a word), discussed the meaning of the morphemes, reviewed the spelling of these words and have used puzzles and games to build comfort and familiarity with their spelling and definition.

Here is an example:

indecipherable

Morphemes: in (not), de (away from), cipher (code/secret), able (can do)

Meaning: not able to take away the code

This week we will have a spelling test on some of the words we studied. If your child wishes to study these words, they may review the list. The work we have done in class should be enough preparation; however, extra review is never a bad idea!

illegible

immerse

impression

irresponsible

inventor

illuminate

immune

irrelevant

immature

inactive

inflate

invest

immobile

inject

inaccurate

immediate

illegal

disconnect

disappear

discomfort

diffuse

difficulty

disfigure

dislike

Social Studies and Science

Just before the two week break, we wrapped up our study of Indigenous communities and the impact of contact with Europeans. The students were engaged and interested during this topic of study. They particularly enjoyed the research project where they created a slideshow.

Last week, we started our exploration of the human body. I am introducing five major organ systems to the students and then they will choose one to learn about in more detail. I think the students will find this inquiry opportunity interesting! We will also be talking about the impact of technological innovations on human health. There are lots of links on Google Classroom if you want to learn more about the organ systems!

Multiplication

This week we will begin looking at multiplying whole numbers.  We will review multiplication facts a bit each day this week. I would encourage many students to review their facts at home using flash cards. Using xtramath is another option; however, you must complete the addition and subtraction sections before you can start multiplication.  Committing these facts to memory will be even more important when we begin division.

Here's a look at the skills we will cover:

Grade 5
-multiply two-digit whole numbers by two-digit whole numbers using estimation, algorithms and other strategies
-divide three-digit whole numbers by one-digit whole numbers
-multiply decimal numbers by 10, 100, 1000 and 10 000 and divide decimal numbers by 10 and 100 suing mental strategies
-use estimation when solving problems to judge the reasonableness of a solution

Shortly, I will introduce the students to "the array" or "area model."  Take a look:

This strategy is called the area model because it uses the idea of area where you find the number of squares it takes to cover a rectangle using length x width. I compare it to an array where you can fit 60 x's across and 20 x's down so the box can fit 60 x's, 20 times. 

The traditional algorithm is another method we'll use to find products.

Stay tuned for more updates and remind your son or daughter to work on their math facts.  Thanks!
