Cerrito Creek

Fifth graders began a unit on three-dimensional geometry this morning. They built boxes with grid paper and filled them with multi-link cubes to find volume. By the end of class, most of them arrived at the formula for finding the volume of a rectangular prism.

Homework:
Chapters 13 and 14 of Island of the Blue Dolphins + summary (see handout)
Spelling practice

4th grade math
Today's questions:  What is data? How can we describe a set of data?
Today we began our next unit, Describing the Shape of the Data, about data analysis and probability.  We met in half groups of students, with one group working in Strawberry with Jeff and Stephen, and one group in Wildcat with Sima. Students counted the number of raisins in small boxes and started organizing the class data to answer questions like: What is a typical amount of raising in a box?

Fourth grade math homework: 
Cut out and bring in 2 examples of graphs from newspapers, magazines, or web sites.
Give your parents their letter about this unit, which you can download here.
Due Wednesday, 10/26/11.

Fifth graders began a new unit today on 3-D geometry. Read all about it in TERC's family letter (part 1 and 2). They built boxes and fit multi-link cubes inside to find volume. Most of them arrived at the formula for finding the volume of a rectangular prism by the end of class today and will formally learn it on Wednesday. Cerrito is off to China Town tomorrow, so there will be no regular homework tonight. However, the problem of the week is due Friday, and students should work on it for homework this week.
