Students learned that there are special rules for dividing numbers by 1 and by 0.

**Rule: A number divided by 1 is that number.**

**Examples: 4 / 1 = 4 or 55 / 1 = 55**

**Rule: A number divided by itself (except 0) is 1.**

Students didn't get to watch Division Rules video because my projector lamp went out :(

Examples: 17 / 17 = 1 or 135 / 135 = 1

Rule: Zero divided by a number (

__except 0__) is 0.
Examples: 0 / 4 = 0 or 0 / 15 = 0

Rule: You

Examples: 7 / 0 cannot be done. 12 / 0 cannot be done.

Students learned to use patterns to multiply by multiples of 10s and hundreds.

An example we talked about in class was:

2x3=6

2x30=60

2x300=600

EX: 6x800 --- First multiply the first non zero digit, 6 times 8 which equals 48 then add 2 zeros, so your product is 4800.

Students learned CUBES for solving word problems. I sent a copy of CUBES home for students to keep and use for future assignments.

**[Edit] Reminders:**

-All grades are updated in the grade book/database; this includes test that students took on Friday 10/4/13.

-The end of the first 9 weeks is October 18, 2013. All make up or late work is due Tuesday, October 15, 2013. I will not take any missing work after Tuesday 10/15/13.

-Within the next week, week and a half, we will be taking Math Benchmark 1. I have scheduled Benchmark 1 for Wednesday 10/16/13. I will keep you all updated if there are any changes.
