Dear Parents,

Last week was a little crazy with Halloween on Wednesday and then some very tired students (and maybe 2 second grade teachers) on Thursday!  Even with celebrating Halloween midweek, second grade students were busy learning.

This week Oasis Academy will be hosting The Enchanted Forest Book Fair.  Students will go as a class to preview during the first part of the week.  They may go to purchase books before school, during lunch, or after school.  Family Night will be Thursday, November 8th from 6:00-8:00 pm. Hopefully you will be able to attend!!

Other events going on are the Canned Food Drive and the Coat Drive sponsored by the National Honor Society.  Please consider donating to these worthy drives!

Remember, Oasis Academy will not be in session on Monday, November 12th in observation of Veteran’s Day!

Math

Last week 2nd grade mathematicians became pros at using the open number line strategy!!  Students have used this strategy to add and subtract numbers within 100. This week students will be reviewing open number line and learning to add and subtract using partial sum and partial difference.  Below is a preview of the partial difference strategy.

5 6 →     50 + 6      1. Show the minuend in expanded form.

–   3 2  →    30  + 2     2.  Show the subtrahend in expanded form.

2 0          20 + 4     3.  Subtract the tens and ones.

+     4   4.  Add the partial differences (tens and ones)  to get the difference.

2  4

We realize that these strategies are very different from the traditional algorithm that we all learned but knowing these strategies helps to deepen the mathematical understanding of adding and subtracting.

Language

Second graders are learning about adjectives.  Students will be using their Chromebooks to create a document that will include a picture that each student will select.  They will then create an adjective triangle describing their picture.

Writing

The second graders are still working on their Opinion piece, using the acronym OREO!  We are in the conferencing part of this writing.  Hopefully this opinion piece (the best holiday) will be posted on the bulletin board by the end of the week.

Projects

Students continue to work on the concept of matter.  This week students used the information from last week (testing salt, sand, cornstarch, and baking soda) to determine which substances were in 2 different mixtures.

Wishing everyone a fabulous week!

Sincerely,

Mrs. Bloomfield
