Multiples and Factors: Rotation Day B

Bell Ringer:  Which One Doesn't Belong

I love this activity!  Students are asked to look at the numbers and decide which one doesn't belong and explain.  A few of the answers today:

• 9, it's the only single digit number
• 16, it's the only even number
• 43, it's the only prime number
• 9, it's the only one whose digits do not create a sum of 7
• 43, the other numbers can be made my double factors (3x3, 4x4, 5x5)
• 25, it's the only one whose one's digit is not a multiple of 3

Lesson Frame:

• We will work on activities that focus on factors and multiples of numbers.
• I will describe which I like better, finding factors or finding multiples of a number and support my choice.

Lesson:

• Group 1
• Khan Academy - Assignments on Factors
• Think Through Math
• Group 2
• Think Through Math
• Teacher Table - visited about UIL Number Sense and worked with Roman Numerals
• Group 3
• Teacher Table - visited about UIL Number Sense and worked with Roman Numerals
• Think Through Math
• Group 4
• Think Through Math
• Khan Academy - Assignments on Factors

The UIL Number Sense group will be a part of my rotations once a week. During that time, students will take Number Sense tests. Learning new shortcuts and strategies will have to happen on their own time. To help with this, I am using:

This book works in conjunction with a set of videos found at MathNinja.org.  I intend for my students to be self motivated self learners and this is an excellent way to begin!
