Week of September 30, 2013 - October 4, 2013

Monday, September 30, 2013

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.

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 cannot divide a number by zero.
Examples: 7 / 0 cannot be done. 12 / 0 cannot be done.

 

 

 

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

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.
