Wonderful Wednesday!!

More student tips on using Powtoon:

• your voiceover for an individual slide can be a max of 21 secs
• you can record a voiceover for all the slides at once rather than individually
• you can put music in the background of your slides by going to the sound categorey and clicking add music

We began the day continuing with fractions. 

A fraction like  34 says we have 3 out of the 4 parts the whole is divided into.

EXAMPLE:

14 + 
14

Step 1. The bottom numbers (the denominators) are already the same. Go straight to step 2.
Step 2. Add the top numbers and put the answer over the same denominator:

14 + 14 = 1 + 14 = 24

Step 3. Simplify the fraction:

24 = 12

14	+	14

=

24

=

12

... and do you see how 24 is simpler as 12 ? (see Equivalent Fractions.)

EXAMPLE: 

13 + 16

Step 1: The bottom numbers are different. See how the slices are different sizes?

13

+

16

=

?

We need to make them the same before we can continue, because we can't add them like that.

The number "6" is twice as big as "3", so to make the bottom numbers the same we can multiply the top and bottom of the first fraction by 2, like this:

× 2

13

=

26

× 2

Important: you multiply both top and bottom by the same amount,
to keep the value of the fraction the same

Now the fractions have the same bottom number ("6"), and our question looks like this:

26

+

16

The bottom numbers are now the same, so we can go to step 2.

Step 2: Add the top numbers and put them over the same denominator:

26 + 16 = 2 + 16 = 36

 Simplify the fraction:

36 = 12

In picture form the whole answer looks like this:

26

+

16

=

36

=

12

Success Criteria for today:

Success Criteria:

-I can add fractions by using equivalent fractions using the same denominator 

-I can use my knowledge of LCM to find the same denominator

-I understand that equivalent fractions need to have the same denominator 

We also practiced for the Christmas concert.

After first recess and lunch we had a classroom conversation about chapters 11-15 of Tuck Everlasting.

Then we continued working on our Powtoon about our chosen Aboriginal group.

After second recess and lunch, Ms. Alysia and Ms. Alessia put together a party for us to celebrate having their wonderful help during this term. 

Homework:

1.    Novel Study: Chapters 16 and 17: pages 43-47

2.    UOI: finish slides for Powtoon and begin script

3.    Math sheets
