Tides, books and creatures

Homework:

4th Grade Math: Packet due on Friday (no math class both Wednesday & Thursday due to field trips) We are still not able to scan materials so I am unable to post the assignment.  In class we recently reviewed different methods in multiplication (distributive property, lattice and standard algorithm).  The students are currently creating board games based on probability rolls with dice.  The students collected data about dice rolls and are using this information to plan a game. Requirements include using probability and other mathematical operations or concepts.

5th Grade Math:  Problem pages due tomorrow.

Reading:  20 minutes/night

Clothing Consideration this Week and Next:  Our projects this week will be getting messier and messier.  Everyone is bound to get a bit of paper mache or tempera paint

Upcoming Events:

December 12: Field trip to Duxbury Reef (permission form coming home today)

December 19, 8:30-10:00 am:  Ocean and Kelp Forest classroom event.  Family members invited to the "opening" of our Kelp Forest installation.  Both Cerrito and Strawberry will be open for visiting the ocean related displays.

December 20:  The students are in the midst of helping us plan our day before break.  We are looking at food, crafts (including candle making) and other activities.  This event is being planned by the kids and teachers.  We will get notice out soon about any items students plan to bring in to share.  

Thank you all for the healthy donations of newspaper.  We are now well stocked and will not need more for quite a while.

Today in Strawberry:  A big science day - we learned about the rotation of the earth around the sun and the reason for seasons.  This led to the orbit of the moon and how all of the aspects of earth's tilt, gravitational pull of sun and moon, earth's gravity and centrifugal force caused by rotation affect the ocean's tides.  The kids drew models of Neap and Spring tides, and analyzed a tide table to search out high and low tides.

The second part of our day included finishing book club projects and continuing work on the kelp forest.
