Hi parents,
We had a pretty good day today. The morning was tough though. The 'missing number' addition and subtraction problems were such a challenge. Spirits were on the brink of being crushed - so we took a few steps back and reviewed the idea of 'fact families'.
We did a few examples of fact families as a class. They look like this:
7 + 13 = 20
13 + 7 = 20
20 - 13 = 7
20 - 7 = 13
I'm hoping that by reviewing basic fact families, students will be able to build a stronger understanding of how addition and subtraction are related, and apply the same understanding to successfully rewrite and solve more complicated problems. On the math quiz, there will be problems like:
1,402 + ___ = 2,105
Same idea, but with bigger numbers. I think we can get there with practice. But because we may need some extra time, the math quiz will be postponed until Tuesday, November 28.
In the afternoon, we started reading A Rover's Story. We learned about Mars, and we learned about Mars Rovers. These videos are interesting!
