Dojo will be used for behavior only. Points can be traded in for special treats or things they may do in class.

Remind will be the sole form of communication with parents.

Students will also need to bring at least 2 books from home each day to class.

If we go back to virtual learning, students will view google classroom for assignments, meetings, and schedule.

This year your child will not be receiving nightly written homework. :)

However, a newsletter that you will need to review will come home with suggested activities that your child may complete, announcements,

and assessment dates on Mondays along with completed work. Also, there may be times that your child will bring home a study guide to review for assessments.

Please keep all completed math in a place at home to review for unit assessments.

Important look at the new way to do math below:

New Math for Parents:

New math: 65 - 27= 38

You can solve many ways: Subtract 2 tens from 65 because there

are 2 tens in 27. 65-20=45 Then subtract 7 ones from 45 because

there are 7 ones in 27. 45-7=38 38 is your answer!

65= 60+5

-27= 20+7

40-2=38 you get a negative number when you subtract 5-7

Example: 67 + 25 = __

Place Value Strategy

I broke both 67 and 25 into tens and ones. 6 tens plus 2 tens equals 8 tens. Then I added the ones. 7 ones plus 5 ones equals 12 ones. I then combined my tens and ones. 8 tens plus 12 ones equals 92.

Counting On and Decomposing a Number Leading to Ten

I wanted to start with 67 and then break 25 apart. I started with 67 and counted on to my next ten. 67 plus 3 gets me to 70. Then I added 2 more to get to 72. I then added my 20 and got to 92.

Commutative Property

I broke 67 and 25 into tens and ones so I had to add 60 + 7 + 20 + 5. I added 60 and 20 first to get 80. Then I added 7 to get 87. Then I added 5 more. My answer is 92.

Students may solve this problem in a variety of ways. Examples are:

 50 - 12

50 – 10 is 40, then 40 – 2 is 38.

50 – 2 is 48, them 48 – 10 is 38.

You need 8 more to get to 20 from 12, then 30 more to get to 50, so the answer is 8 + 30 or 38.

Note: Students who use this method are actually finding the difference between the two numbers

and not simply "taking away." This is a wonderful opportunity to discuss different approaches to subtraction.

99 + 17

Students may solve this problem in a variety of ways. Examples are:99 and 1 more is 100, 100 + 17 is 117,

but take 1 away that was added to the 99 to get 100, so the answer is 116.

Some may attempt a traditional algorithm, but should notice that this is more cumbersome that examining

the numbers and using the ideas above to compute.
