My Take
Code.org is free and without advertisements or requests to purchase additional content. It teaches coding to students, beginning at the pre-reader stage. There are unplugged activities provided to bridge the plugged activities, so students gain a deeper understanding of the coding concepts.
How I Use It
I first used Code.org during the Hour of Code while pairing students in groups of two. My students absolutely loved it and I loved watching them work together to solve challenges.
