| May the editing begin. Groups will have the challenge of building a shared vision and compromising. Lots of cooks in the kitchen! |

| To encourage volume, Gunnar had the students sing at each other, a kind of singing contest. This is the dot.com song. |

Math
Fourth grade math
Purple group: As we wind down the school year, students are focusing on good habits in computation. For example, when doing a computation:
1. Make an estimate.
2. Is it an under- or over-estimate?
3. Compute the answer.
4. Compare it to your estimate.
5. Is your answer reasonable?
We practiced estimating addition and subtraction solutions, and learned a new way to think about subtraction problems, using a number line. Although the standard algorithm is efficient, adding up using number lines is a flexible method for subtraction that can often be done in your head more easily. Students also practiced keeping track of all the parts of a double-digit multiplication problem, using story situations and arrays.
Fourth grade math homework, due tomorrow
Purple group: Unit 8, pages 16, 17, 18
Blue Group: We warmed up with estimation practice, and determining whether our estimates were high or low. While the students have successfully learned algorithms for multiplying double digit numbers, we considered other methods of breaking the problems a part by using arrays to model what is happening with multiplication. Homework: Story problems with money.
Research paper due tomorrow.
