News from Room 208

Math

This week we practiced subtraction, but with bigger numbers into the millions place. We learned about inverse operations and how we can use addition to see if our difference is correct. We also used estimation in a subtraction problem to see if our answer was reasonable. We worked on two-step word problems, which can always be a challenge for students. We pulled out keywords and learned different strategies to solve these word problems. Our Unit test will be next week Monday, October 19th. The study guides will be sent home tonight to review over the weekend. Things to practice with your children to prep them for the test:

*Rounding to nearest place value (up to millions)

*Writing numbers in standard, word, and expanded form (making sure they are not writing "two hundred and five")

*Adding and subtracting numbers into the millions (with regrouping and ungrouping)

*Estimating to see if an answer is reasonable

*One step and two step word problems with addition and subtraction.

Social Studies

We learned new social studies vocabulary words this week, and how they are related to thinking like a historian. Those words are:

*Interpret

*Investigate

*Evidence

*Artifact

*Primary and secondary sources

The kids learned that historians are a lot like detectives; they try to put together clues to figure out what happened in the past. Historians need to have artifacts as evidence to prove their ideas. They also use primary and secondary sources to discover what happened in the past. We learned that historians need to gather information from different points of view to really know what happened. Historians also ask questions when they see artifacts to determine what they are and why they are important. We will be doing something similar to this in class. A letter will be sent home today, as well as a paper bag, for a small social studies project for next Tuesday, October 20th. We are going to be gathering artifacts from home that tell a little bit about us. The artifacts must remain a mystery, so please don't include artifacts with your child's name on it. Our class will be looking at the paper bags in groups and asking questions, just like historians do! A copy of this letter is also attached below.
