One of the largest road blocks to having K-5 teachers implement computer programming skills is TIME! I have often heard my teachers saying "I just can't add more more thing to the day."
That's why I think that the success of incorporating computer science skills INTO the curriculum is essential! Currently, I am looking at the CCSS and the learning progressions. Using Scratch (www.scratch.mit.edu) - a FREE website, I am working on creating lessons that are aligned to the CCSS in ELA and math.
Please feel free to use the FREE resources and worksheets for the Hour Of code week - December 9th thru December 15th! The worksheets take the Kindergarten student through the process of creating a holiday card through various screen shots.
