Good Morning Mighty and Marvelous Grade 4/5!
I hope you had a happy and healthy March Break. We will start our day as usual....
In the name of the Father, the Son and the Holy Spirit. Amen.
Please take a moment and offer your intentions.
Our Lenten deed today is to say a "Hail Mary" for the sick, poor and suffering.
Bell Work
I've decided to keep going with mentor sentences. Write your mentor sentence in your small green notebook. Better yet, if you have access to a computer, write it as a Google document in your Google drive and you can share your work with me at the end of the week. Here is the link to the book with the mentor sentence, My Great Aunt Arizona:
Day 1: What do notice about the mentor sentence?
When spring came, they helped Papa tap the maple trees and catch the sap in buckets.
Math
Here is a printable multiplication chart:
Here is a copy of a multiplication chart.
Please use it and don’t guess at your facts.
If you were absent from school on the Friday before March Break, I shared a file with you on your Google drive. The booklet it there. You don't have to print it out. You can write your answers on lined paper or any other paper you have at home.
The first page of your multiplication and
division booklet, page 10 at the bottom, talks about squares of numbers. Like it says on the first line
of your booklet, a square is just a number multiplied by itself. We show squares
using the exponent 2. An exponent is just a smaller number written in the top right corner of the base number. For now, we
need only to know that a number to the exponent of 2 or “squared” just means
multiplying that number by itself.
Example:
92 = 9 x 9 = 81
Below is a bit of background about exponents.
We can also show a number “squared” using an
area model. We can show 92 on graph or grid paper by drawing a
square with a length and width of nine squares. If you counted all the squares,
and I encourage you to count the squares on page 10 of your booklet, you will
find that the total squares are equal to the product. In the example below the
square has an AREA of 81 squares because 9 x 9 = 81.
Don't forget to highlight all the squares on your multiplication chart. That takes care of page 1. Pretty easy, right? I bet some of you already finished!
Page 11
When we count by a number we are showing the MULTIPLES of that number. Knowing the multiples of a number really comes in handy in the older grades when working with fractions. Knowing your multiples is important. When you complete the VENN diagram, use the multiples you wrote in the question above. The last question on page 2 (#3), they want you to keep counting by 2 and 3 to get larger multiples.
2, 4, 6, 8, 10 , 12, 14, 16, 18, 20, 22, 24.......................60
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, ....................60
Which numbers are multiples of both numbers? Circle them on your paper. Those are the numbers that would go in the middle of your VENN diagram.
Wow, we are moving quickly.... page 12 (third page) already.
Page 12
The factors of any number are all the numbers that multiply to give that number.
If you do not know your multiplication table by heart, the factors are going to be challenging. On your multiplication table, look at all the places that the number / multiple appears. Those are going to be your factors.
I like how the booklet using grid paper to show the product. It will be very helpful when we study areas of rectangles.
For question number 1) on page 12:
The first array shows 1 x 12 = 12 What are they other factors of 12? What other numbers multiply together to give you 12? They give you all the arrays for 12 but we can also look on the multiplication chart below.
12 x 1 = 12 (forgot to show that one on the chart above...oops!)
1 x 12 = 12
2 x 6 = 12
6 x 2 = 12
3 x 4 = 12
4 x 3 = 12
We don't need to repeat the same numbers. A good rule is to write the factors in order. So the factors of 12 are 1, 2, 3, 4, 6, 12
1 and the number you are writing the factors for are always going to be factors.
In the video link below, he talks about using a divisibility test to check if a number is a factor of a given number. It's another way you can find all the factors. Use the multiplication chart first, then use his method to make sure you didn't forget any factors. Sometimes the factors of larger multiples are not on a multiplication chart. Don't forget that every even number will have what number as a factor? 2 of course!
Extra practice in your green math notebook:
Write the factors of:
1) 36
2 ) 18
3) 28
REVIEW QUESTION
Before we wrap up math for today, I want to go over the relationship between the length, width and the perimeter of rectangles. Hopefully grade 5 you completed your booklet. There are few kinds of questions I want to make sure you understand.
There were 3 "formulas" for the perimeter of rectangles:
Perimeter = l + l + w + w
Perimeter = double length + double width or 2 x length + 2 x width
Perimeter = (length + width) doubled or (length + width) x 2
The first formula applies to any shape... just add up the lengths of all the sides.
The other two involve an understanding that in a rectangle there are 2 identical widths and 2 identical lengths. Some of you are probably thinking I know that, but can you apply that knowledge?
If you know the perimeter of a rectangle and divide it in two or half, what are you left with? You are left with the length + width. SAY THAT OUT LOUD TEN TIMES.
What are all the rectangles with a perimeter of 18 cm? List them in a chart in your green notebook.
Step 1: Divide 18 cm in half
Step 2: List all the numbers that add to that number
Step 3: Add the numbers and double them to check (you should get a perimeter of 18 cm each time)

Writing
Complete the following topic sentence in your green notebook with your choice of pet. Write three reasons and include explanation for each. If you prefer to write it as a Google document and share it with me, that's wonderful.
Cats and dogs are just fine pets for most people. If you ask me, a(n) ______________ would be the best pet ever. I know what you are thinking, but let me explain.
Hmm.... I wonder which animal you will choose. Be creative!
Art
Here's a link you can use to find some "how to draw" videos on YouTube. I believe they have different levels.
That it's almost impossible for most people to lick their own elbow?
Sending everyone virtual hugs... God bless.
