This is not some ordinary Compare and Contrast. It's actually a whole lot of fun, not to mention sneakily intellectual. Keep your kids interested in the Parcc with actually interesting, diverse sources that make a person want to explore the similarities and differences of the four sources. Common Core Rich! This is like sneaking apple sauce into the brownie mix. The kids won't know they're becoming intellectuals! They won't realize this is Parcc practice! Hey, why not add some pureed spinach to that chocolatey dessert in while you're at it?! Miss A does the equivalent here!
