Hour of Code + Scratch + CCSS: 7th Grade Math, Scale Factor

The second in a series of lesson plans introducing programming while aligning to the Common Core State Standards. I'm hoping that more teachers will participate in Hour of Code if the content is material they have to teach anyway. In this lesson, students use the pen, motion, and loop blocks to draw a square, then create a program to scale the square. 

CCSS.Math.Content.7.G.A.1 Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at another scale.
