Dear Parents,
Miss Garcia and myself hope that everyone enjoyed the extra long weekend! It was so nice to have an extra day but we are ready for another great week in 2nd grade!
Students have continued to work on adding and subtracting with renaming within 1,000. This past week students focused on the branch method. Students picked up on this strategy quickly.
This week we are focusing on Partial Sums and Differences. The students should be familiar with this strategy and have applied it previously with addition and subtraction. Here are some examples of homework this week.
Partial Sums with Renaming
Example:
3 6 6 → 300 + 60 + 6 1. Show the first addend in expanded form.
+ 4 5 7 → 400 + 50 + 7 2. Show the second addend in expanded form.
7 0 0 700 + 110 + 13 3. Add the hundreds, then the tens, and the ones.
1 1 0 4. Add the partial sums--700 + 110 + 13 =823
1 3
8 2 3
Partial Differences With Renaming
Example:
4 6 7 → 400 + 60 + 7 1. Show the minuend in expanded form.
- 2 9 8 → 200 + 90 + 8 2. Show the subtrahend in expanded form.
2 0 0 200 - 30 - 1 3. Subtract the hundreds, then the tens, and the ones.
- 3 0 4. Add the partial differences--200 - 30 - 1 = 169
1 7 0 5. Watch out for negative numbers!!
- 1
1 6 9
Here is what we will be working on for homework this week:
Tuesday

Worksheet: Partial Sums

Wednesday

Worksheet: Partial Differences
|
Thursday
|
Worksheet: Partial Sums and Differences in Word Problems

Language
In language, students have been learning about apostrophes. We will work with apostrophes in contractions and possessive nouns. We have started focusing on using apostrophes in contractions.
I am = I’m do not = don’t we are = we’re that is = that’s
Writing/Projects
Students have been working with their partners on their Decade Projects. This research has been interesting as students explore their decades. This has been a very labor intensive project so far and part of the project time is overlapping with our writing time.
Sad News…
As many of you know, the second grade classes have been very fortunate to Miss Darity to teach Zumba for PE every Tuesday. Last Tuesday was our last Zumba Day. Below are some pictures from the last Zumba class. Miss Garcia, myself, and all the second graders appreciate Miss Darity sharing her time and talent with us over the past five months.
We are now actively searching for another parent to help with second grade PE on Tuesdays. If you would like to help please let Miss Garcia or myself know!
Sincerely,
Anne Bloomfield and Shannon Garcia
