Algorithms, Persuasion, and Reformed Rocks

Expedition

After finishing our experiment with sedimentary rock, we looked at another type of rock this week--metamorphic.  In a matter of minutes we used modeling clay to recreate the process that forms metamorphic rock over thousands of years. Beforehand, we defined metamorphic (meta = change; morph = shape or form). We then discussed the rock cycle-- how the earth's primary materials move through the different rock types over and over again. 

Math

We are now in unit two.  We began with an estimating exercise and then defined the term "algorithm," which is a step-by-step process used to solve a particular type of problem.  We then reviewed and practiced different algorithms for addition and subtraction.  Ask your child what these algorithms are: partial sums, trade-first, and partial differences.

Reading

Our reading skill in focus this week was questioning.  We tracked the kinds of questions we ask in our heads as we read, the answers we are able to get for our questions, and the strategies we use to get the answers--such as rereading, reading ahead, looking to outside sources, inferring from the text, etc.

Writing

Our new unit of study is on editorials--the expression of an opinion to persuade people to take an action or change their thinking.  So far we've begun listing things we feel strongly about and examined one mentor text.  In writing, we also took time to reflect on our voyage experience for our portfolios.

Morning Meeting

We begin our days with morning meeting--a twenty minute time with greetings, activities, sharing, and announcements.  On Monday each week, we drum for our meeting.
