Math Update

We finished our Extending Numbers and Operations unit this week. This was definitely the most challenging unit thus far as it pushed the kids to use everything we've learned already this year and apply it when adding and subtracting larger numbers. Students also used their knowledge from our place value unit. Story problems continue getting more challenging as students need to understand what the question is asking them to do and identify what information is already given. Students are needing to learn to move from one type of story problem to another with ease and pick an appropriate strategy. We've especially been working on the missing addend concept. After this unit, students should be able to:

1. Use a variety of strategies to add and subtract within 100:
    -Using Concrete Models or Drawings
    -Using Place Value (add tens to tens and ones to ones)
    -Demonstrating an understanding of the Relationship Between Addition and Subtraction\
2. Provide verbal or written explanation of the reasoning used (words).
3.Add a two-digit and a one-digit number within 100.
4.Add a two-digit number and a multiple of ten (in the range of 10-90).
5.Subtract a multiple of ten (in the range of 10-90) from a multiple of ten (in the range of 10-90).
6.Compose and decompose tens when necessary.
7.Mentally add 10 to a given 2-digit number.
8.Mentally subtract 10 from a given 2-digit number.

Next week we begin our new math unit on GEOMETRY. This unit is always a lot of fun. Our essential questions for the unit are: How do we describe shapes and objects?
How can geometric figures be constructed?

We really emphasize the understanding of how shapes can be composed and decomposed as well as describing attributes and comparing shapes.
