Now we're moving on to Bundle Two which is all about Addition, Subtraction, and Financial Literacy. This bundle is three weeks.
Big Idea
The students are expected to use their knowledge of place value to estimate sums and differences as well as add and subtract whole numbers with regrouping.

Guiding Questions
Why are estimating and rounding helpful strategies?
How do you add and subtract whole numbers up to the billions place with regrouping?

What real world applications would you use addition and subtraction for? (perimeter, profit)
- Sum
- Difference
- Estimate
- Round
- Compatible numbers
- Intervals (of time)
- Perimeter
- Profit
- Expenses
I want to have several problems about elapsed time. That one is so tricky!
For example:
Karyme wakes up at 7:45. She gets to school at 9:15. How long has she been awake but the time she gets to school?
To teach perimeter I definitely want to use tape and make different shapes for them to measure.
