Week of October 10

Happy Monday!  I'm excited to get the ball rolling this week.  We will be starting two new units of study: Least Common Multiple & Plate Tectonics!

For our work in math with LCM, we will have a few lessons with homework.  Then, on Thursday, we will have a quiz on what you learned.  Check out this math.com site if you need a refresher.

In science, we will be talking about plate tectonics.  I have some really cool Montessori materials to help you understand the theory of continental drift.  You will also be working on a choice sheet called "Clean Your Plate" to help guide your studies of plate tectonics.  It will be due NEXT Friday.  Here is a copy of the powerpoint presentation you will see Monday:



 You will have a vocabulary test on Friday on these words:


lithosphere- the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle.
asthenosphere- the soft layer of the mantle on which the tectonic plates move.
mesosphere- the strong, lower part of the mantle between the asthenosphere and the outer core.
continental drift- the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
convergent boundary- the boundary formed by the collision of two lithospheric plates.
divergent boundary- the boundary between two tectonic plates that are moving away from each other
transform boundary- the boundary between tectonic plates that are sliding past each other horizontally
fault- a break in a body of rock along which one block slides relative to another
uplift- the rising of regions of the Earth’s crust to higher elevations
subsidence- the sinking of regions of the Earth’s crust to lower elevations

Parent/Teacher/Student conferences are coming up next week.  I will send home conference request sheets this week.  Also, keep in mind that Scholastic Book Orders are due on Thursday.  Please pay with cash or make you check payable to "Charles Ellis Montessori".

I'm ready for another great week at Ellis!  I hope you are, too!

Mr. Trent
