 ## 2. What does it do?
 
 **2.1) Describe the function of each block in the chart below. If the block accepts arguments (contains values that you can change), be sure to test out a few different ones to make sure you fully understand what those values mean. The first one is already filled in for example.**
 
 | Block | Function |
 | -- | -- |
-|![point in direction]()| *Changes the direction that the sprite is facing. The argument indicates the number of degrees the sprite turns clockwise from pointing upwards. When the argument is "90", the sprite points right, and so on.* |
-|![think]()||
-|![play notes]()||
-|![set pen color]()||
-|![glide]()||
-|![repeat]()||
-|![change pen size]()||
-|![set effect]()||
-|![go to x-y]()||
-|![set size]()||
-|![rest for beats]()||
-|![point towards]()| |

 **2.2) At this point, you may be noticing some patterns. Use what you've learned from exploring these blocks to answer the questions below about each block category.**
