 ## Lecture: Functions & Callbacks
 The [presentation](FunctionsAndCallbacks.pptx) reviews functions, and shows how they can be used for callbacks. There are a few code examples.

 # Warm-Up: Function Machine
 In JavaScript, [functions](https://javascript.info/function-basics) are a way to run a piece of code on-demand. Parameters are used as function input, and returns are used to give back an output. In math, the concept of functions is similar - often, math functions take some sort of input, and produce an output. In this warm-up, play a math-inspired function game to practice using input and output.

-The goal is to figure out the "code" for a math function based on its input and output.
-
-- Start with the **Beginner** mode, then move onto the **Advanced**
-- Click **Instructions** in the upper right to see some detailed instructions
-- Choose a difficulty with the numbers in the **Choose an Activity Level** box at the bottom
-- Try to figure out the **Advanced Level 3** - that's the hardest one!
-
-## Additional Games
-There are some additional math/code games that are not directly related to the concept of functions, but feel free to try them out:
-
-- [Follow the Code](https://www.mathplayground.com/follow_the_code.html)
-- [Equation Creations - Drawing with Math](https://www.mathplayground.com/equation_creations.html)
-- [Candy Challenge - Algebra](https://www.mathplayground.com/candy_challenge_game.html)
-- [Slyers](https://www.mathplayground.com/logic_slydrs.html)
+The goal is to use the proper function to match the input bubbles to the bubbles on the field already. Good luck!
