Teachers, save “L6-7NUM - Adding and Subtracting Integers” to assign it to your class.

You and a friend are to visit and play this Scratch game against each other: https://scratch.mit.edu/projects/279021214/ While playing the game, be sure to take notice of what happens when the operation and integer cards are dealt, what the bat says after the result, and the movement of the balloon. Using the recording feature, you are to record what you notice happening to these objects. --------------------- EXTENSION BELOW ---------------------------------------------------------- There is also a version of the game that is broken, and that learners can fix! Visit the video tutorial link and the Scratch starter project to follow along fixing the game while thinking about the logic for adding and subtracting integers.
