Here is a summary of what happened in our classroom:In Langauge Arts...
- Our essential question is
**How does the earth change?**We read a text called**Into the Sea.**Using this text, students learned about cause and effect. Students learned the causes of beach erosion and the effects beach erosion can have on the infrastructure of a community. Students learned how to use partial-flow maps and multi-flow maps to show cause and effects of erosion.
- Students read more informational text on earth's changes. One text was about flash flooding and another about earthquakes. Both these natural circumstances can make changes to our earth. The focus this week was on multi-flow maps, hence students learned how to identify both the causes and effects at the same time. In doing so students addressed the standard
**2.RI.2.3 Describe the connection between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text.**
In math...- Students learned about estimation with a curved number line to help them determine which ten a number is closer to. Then after estimating, students found the differences between 2 two-digit numbers. The video below shows the idea of a curved number line, although the numbers in the video are larger than the numbers our students estimated, the concept still applies.
- Students learned to subtract a two-digit number from a three-digit number when decomposing the ten. For example in the problem, 162 - 28 = ? students learned to trade a ten for 10-ones. So instead of representing 162 as 1-hundred, 6-tens, and 2-ones, they draw the numbers as 1-hundred, 5-tens, and 12-ones.
- Students then transferred this same concept of trading into the hundreds place. For example in a problem like 126 - 41 = ? students learned to trade the hundred for 10-tens. Instead of representing 126 as 1-hundred, 2-tens, and 6-ones, students represented it as 12-tens and 6-ones.
