That is how elementary students at Cherry Hills Christian challenge themselves every day in computer class with “FreeRice.com.” As soon as students are finished with their daily assignment, technology teacher, Kelly Tenkely, allows them to visit Free Rice and play the vocabulary quiz game. With each word definition they guess correctly, 20 grains of rice are donated through the United Nations World Food Program to help fight world hunger. At the end of class, every student records the number of grains of rice they donated that day. Since Thanksgiving, the 305 students in second through fifth grades have donated over 1,197,870 grains of rice. That number continues to grow daily. To help visualize what this much rice looks like, fourth-grader Allie Chambers measured the grains of rice in a tablespoon and did the math to discover there are approximately 7,200 grains of rice in a cup. That means CHC students have made it possible for those in need to cook almost 166 cups of rice creating almost 500 individual servings. To further their exposure to technology and world hunger, the fourth grade classes are just beginning a new project-to create commercials for FreeRice.com using Keynote and Garage Band application. “When we are finished with the commercials my goal is to let Free Rice know about them, although I’m not sure if they will add them to their site or not,” says Mrs. Tenkely. “The goal of the commercials is to teach our kids how to use Keynote and Garage Band but also to teach them about poverty and hunger. We are creating the commercials to tell others about the subject and to tell them about one way that we can help out with Free Rice.” Cherry Hills Christian Principal, Linda Wasem, loves to see students learning a variety of life lessons through daily visits to a website. “Our students are not only learning vocabulary-some of those words are really hard, but they are also learning about people in the world who don’t have enough to eat. Their hearts are moved to give.” For more details about the FreeRice.com vocabulary game, visit FreeRice.com. Find the whole article here.

Dance, Factors Dance: Animated Factorization Diagrams #mathchat

What it is:  Dance, Factors Dance is a fantastic site to visualize factorization diagrams.  The first “tango” is inspired by the digital clock, with a separate diagram for each of the hours, minutes and seconds.  The Factor Conga is a “promenade of primes, composites, and their constituents, arranged with an aesthetically-tuned variation of Yorgey’s rules, one per second.”  I love the way these math factorization dances help students visualize numbers and Prime numbers.  Brilliant!

How to integrate Dance, Factors Dance into the classroom: Dance, Factor Dance is a stupendous way for students to visualize and think about numbers.  I Love the way that the prime numbers are depicted…so easy to see why it is a prime number!  Ask your students to explore this site and identify the patterns they notice in the dance of numbers.  What happens when a number is prime?  When a number is odd?  Even?

Dance, Factors Dance is a fun way to learn more about numbers, it is also a wonderful inspiration for finding the art in math.  How can students use the site as inspiration to create their own math dance?  Could they use stop motion animation and manipulatives to do something similar?  What patterns in math do they notice?  How can they use color and design to help them better understand math?

This site is a great one to explore as a class, as a center on classroom computers, or individually on student devices.  Students can pause the dance, rewind, and fast forward as they explore.

Tips: Be sure to watch (or fast forward) to the three digit numbers…this is where things get really impressive!  As a side note, I learned something today from a fellow teacher.  When looking at numbers in grid form, you know if a number is prime if it can only make one rectangle.  This understanding would have been helpful in math class! Better late than never :)

We have already taught this concept, but this is a perfect way to reinforce it! Thanks!
