We were able to catch up with our Bell Work. Some students are still a bit behind. Look for the sticky notes in your book on Tuesday!

Religion
Ash Wednesday marked the beginning of the season of Lent. During this Lenten season, please think about something that you will do to show that you are "walking in the footsteps of Christ". It's great to make a sacrifice and give up things, but it's also important to DO something. As well, think about five verbs that will describe your actions during this Lenten season e.g. help, pray, forgive ....  You will be writing your ideas on a footprint on Tuesday.

Math
On Friday we reviewed our different addition mental math strategies and talked about two subtraction strategies.
Addition:
Making friendly numbers (multiples of 10)
47 + 29
47 + 3 = 50
50 + 20 = 70
70 + 6 = 76

Decomposing numbers (using expanded form)
47 + 29
40 + 20 = 60
7 + 9 = 16
60 + 10 + 6 = 76

Doubles
39 + 39
40 + 40 = 80
80 - 2 = 78 (must subtract 2 because you added 1 to each 39)

Adding in chunks
47 + 29
47 + 20 = 67
67 + 9 = 76 (you could also add 10 then take one away)

Compensation
47 + 29
46 + 30 = 76 (took one away from 47 and gave it to 29)

You can also combine any of these strategies.

Subtraction:
Counting back (this strategy is only appropriate when you are subtracting a 1 digit number)
85 - 9 (think of the related fact, 15 - 9 = 6)
85 - 9 = 76 (ones place is the same, the tens is one less)

Creating an easier question:
70 - 28 (if we subtract 1 from each number the difference remains the same)
69 - 27 = 42 (subtract tens and ones easily because there is no regrouping)

The goal is to be able to add and subtract any two digit numbers. Try these using your mental math strategies.

58 + 17
50 - 26
41 - 8
39 + 46
29 + 28

Reminders:

• Complete your Mathletics assignments
• Don't forget to catch a bit of the Olympics
