The first site is http://www.wegivebooks.org/ It's a site where you combine the joy of reading with the power of helping others. We Give Books is a new digital initiative that enables anyone with access to the Internet to put books in the hands of children who don't have them, simply by reading online. As a teacher you choose a campaign to support, like Todos a Leer, read a free children's book online today and help donate new storybooks to thousands of children throughout the state of Jalisco in Mexico.
I taught my students to select the tab All Books and age range of 4-7 of any type of book at the main selection. You can specify from 8-10 or teen and even select by author.
My students love to read these books. I was able to check out four mini-laptops from my school to keep in my classroom....so I just log them in and keep them all on that page. There's a quick sign up at the beginning but after that the access if very easy. I have all four laptops signed in at the same time with only one account. Not only are my students reading but we are helping get books into the hands of needy children.
I get a weekly report of how my students are doing. The goal is to reach 100 addition facts mastery. Addition because that's where I started my class. You can select addition and subtraction up to division even beginning algebra. Again, the most important thing is it's free. My students love to go to the computer and beat the teacher at a timed fact exercise, they seem to forget that they are learning.
If you use technology in your classroom please post here what website you use. I would love to continue to expose my students to all the available learning opportunities that are out there.
