Joshua Ton/National Science Foundation Barry Hayes at the Geographic South Pole. It was cold last week in the Midwest. An arctic blast sent temperatures plunging to near-record lows: -32°F in International Falls, Minn. , the self-proclaimed Nation’s Icebox. Brutal cold. But that’s nothing compared to winter at the South Pole, which is beyond brutal. With an elevation of two miles above sea level and with a complete absence of sunlight, the South Pole has an average winter temperature about -72°F.

Many resources are available online for studying the prime factor decomposition of a number. From CIMT there are Interactive Exercises on Prime factors and on Highest Common Factor and Lowest Common Multiple. From Spencer Riley’s TeacherLed the Prime Factor Tree resource provides a very attractive prime factor tree showing the prime factor decomposition for any number from 2 to 99.
How Does the Number Tree Grow? As the numbers descend from the heavens and attach themselves to the growing tree, they look for a specific number on a branch point. The largest divisor (factor) is what they choose. So, for instance, take the number 20. It has the following divisors: (1, 2, 4, 5, and 10). (The number 20 itself is not considered because it can't branch from itself :) So, it chooses 10 as its branch point - as you can see in the tree.
Conceptua Math was conceived three years ago with a mission to complete a K-8 curriculum that is visually interactive and that serves students and their teachers. by Judy Faust Hartnett A whole new generation of digital math products is focused on aligning math learning with the Common Core State Standards. If used properly, then these products can be a great asset to school districts. While researching this topic, Conceptua Math caught my eye because unlike other products, it has not only the student, but the teacher in mind.

This is a list that I created in response to a request that I recently received as direct message on Twitter . A couple of these resources I found through a search in the Diigo community. If you don't have a Diigo account or if you do but you have never searched the community bookmarks, I recommend giving it a try. Who Wants Pizza?
