How to make a timer in Scratch:

1. create a variable called timer.
2. when the flag is clicked, initialize the timer to 10.
3. continually, wait 1 second and check if the timer = 0
1. output the current time either with a sprite or just show the variable
2. If the timer = 0 make either the background or a huge sprite say “Time’s Up”
4. When the flag is clicked, everything should start over.
5. Be creative as to what you want your program to look like.
6. Make sure the timer stops at 0 and does not continue into negatives.
