Week 25
Hello 2nd Grade Families,
This week in math we will continue to work on addition and subtraction strategies within 1,000, focusing on Partial Sums and Partial Differences as our main strategy.
The students have applied the two following strategies: Branching and Open Number Lines for addition and subtraction. This week they 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 is an example of homework this week.
Partial Sums with Renaming
Example:
2 6 4 1. Add the hundreds place.
+ 3 7 2. Add the tens place.
2 0 0 + 0 = 2 0 0 3. Add the ones place.
6 0 + 3 0 = 9 0 4. Add all partial sums.
4 + 7 = + 1 1
200 + 100 + 1 = 301
Here is what we will be working on for homework this week:
